Description
Technical Field
The invention belongs to the technical field of building waterproof construction, and particularly relates to a construction method of a rubber asphalt waterproof coating.
Background
The traditional paint brushing process is that a constructor uses a coater to dip a proper amount of paint in a packaging barrel, the dipped paint is coated on a wall body according to the requirement, and the packaging barrel is filled with more paint, so the packaging barrel is heavier and labor-saving.
When the paint is brushed, as no special tool is used for placing the paint remainder, the coater is required to dip the paint on the packaging barrel and then brush again every 1-2 times of brushing, and the brushing time is too long due to repeated dipping and coating, and the brushing efficiency is low. Particularly, for waterproof paint with high viscosity and high coating temperature, in the process of material sticking and coating, redundant paint on a coater drips to cause paint waste, the difficulty in cleaning the paint dripping underground is increased due to the high viscosity of the paint, and in addition, the redundant paint on the coater can also fall onto the body of a construction worker to cause scald due to the overhigh coating temperature, so that potential safety hazards exist.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provides a construction method of rubber asphalt waterproof paint, which can improve the painting efficiency, save energy, protect environment, be safe and effectively maintain the tidiness of the construction environment.
In order to achieve the purpose, the invention adopts the technical scheme that:
the rubber asphalt waterproof paint construction method uses a hopper as an auxiliary coating tool, the hopper comprises a hopper body with fixed capacity and a handle connected with the hopper body, the upper part of the hopper body is provided with an opening, the front edge of the hopper body is provided with a material port enabling the hopper to be forced to lean upwards and lean on a vertical base surface, and the method comprises the following steps:
s1 glue melting: heating the rubber asphalt waterproof coating to the temperature of 180-250 ℃, and preserving heat for later use;
s2 charging: taking a proper amount of the rubber asphalt waterproof coating processed in the step S1 into the hopper body, holding a handle of the hopper by one hand, and leaning the material opening upwards and obliquely onto a vertical base surface to be coated;
s3 coating: and taking the coating device by the other hand to dip a proper amount of rubber asphalt waterproof coating from the opening of the hopper body, then starting the coating device from the opening to the material port, pushing and coating the coating device onto the vertical base surface right above the material port, after the dipped rubber asphalt waterproof coating is used up, dipping a proper amount of rubber asphalt waterproof coating from the opening of the hopper body again, repeating the pushing and coating process, and after the rubber asphalt waterproof coating in the hopper is used up, repeating the step S2 and the step S3 until the coating of the vertical base surface is finished.
A hopper preferably made of metal; the capacity and the weight of the hopper are smaller than those of the packaging barrel, and when the material opening is attached to the vertical base surface, the vertical base surface shares part of the weight of the hopper, so that too much physical power of construction workers is not consumed in the coating process; the hopper can be used for placing a proper amount of rubber asphalt waterproof paint, so that the process that construction workers repeatedly dip and coat from a packaging barrel is avoided, the brushing time is shortened, and the brushing efficiency is improved.
The rubber asphalt waterproof coating has overlarge viscosity at normal temperature, and needs to be heated and melted to reduce the viscosity so as to improve the coating workability such as leveling property, film forming property and the like of the rubber asphalt waterproof coating, so the heating and melting process of the step S1 is convenient for uniformly coating the rubber asphalt waterproof coating on a base surface; the melting temperature is preferably 180 ℃ to 250 ℃, and the rubber asphalt waterproof coating is melted at the temperature, so that the rubber asphalt waterproof coating can be prevented from being decomposed due to overhigh temperature, the construction viscosity can be quickly reached, and the melting time is shortened.
In step S2, the material opening of the hopper is tilted upward and attached to the vertical base surface to be coated, so that the rubberized asphalt waterproof coating flows backward and gathers at the rear part of the hopper body, and the center of gravity of the hopper is also gathered at the rear part, so as to prevent the rubberized asphalt waterproof coating in the hopper body from flowing out of the material opening when a constructor leans forward or is unstable due to unstable center of gravity of the hopper during the coating process; the rubber asphalt waterproof coating in the hopper body is concentrated to the rear part, so that the rubber asphalt waterproof coating is prevented from being wasted due to the fact that the contact area between the rubber asphalt waterproof coating and the inner surface of the hopper body is too large.
In step S3, hold the hopper on one hand, another hand is taken coating unit and is arrived the material mouth from the opening, and push away to scribble toward the vertical base face directly over the material mouth, coating process can be accomplished to the coordinated operation of both hands, because the coating scope is directly over the material mouth, so in the coating process, unnecessary rubber asphalt waterproof coating will follow the vertical base face directly over the material mouth and drip from the material mouth back to this internally of hopper, in order to avoid rubber asphalt waterproof coating to drip ground and cause the waste, and after avoiding the rubber asphalt waterproof coating that drips ground cools down, viscosity increase and increase the clearance degree of difficulty on ground, thereby can effectively maintain the clean and tidy of construction environment, energy-concerving and environment-protective, in addition, can also prevent that the rubber asphalt waterproof coating of high temperature from dropping to constructor and causing the scald on one' S body, thereby improve.
Preferably, the hopper body comprises a bottom surface, a rear side surface, a left side surface and a right side surface which can form a fixed capacity; the upper edges of the left side surface and the right side surface are inclined downwards, and the front edge of the left side surface, the front edge of the bottom surface and the front edge of the right side surface form a material opening; the handle is connected with the rear side surface; the upper edge of the left side surface, the upper edge of the rear side surface and the upper edge of the right side surface enclose an opening. Bottom surface, left surface, right flank, trailing flank and the preferred body coupling of handle of hopper body for the junction that forms each side of fixed capacity can not form the space, so this internal rubber asphalt waterproof coating of placing of hopper can not leak outward, and handle and hopper body coupling, makes the two connect more stably, thereby the handle is held more firmly, and in addition, the integrated type structure can also simplify machine-shaping's technology. In order to ensure that the hopper is more labor-saving to hold in the coating process, the handle is connected with the rear side surface, namely the handle is close to the gravity center of the hopper containing the rubber asphalt waterproof coating.
During coating, in order to prevent the rubber asphalt waterproof coating from leaking out of the material port, the rubber asphalt waterproof coating is gathered to the rear part of the hopper body, in other words, the front part of the hopper body does not play a role of containing the rubber asphalt waterproof coating, namely, the front part of the hopper body mainly plays a role of stably leaning on a vertical base surface, and if the capacity of the hopper is too large, the labor consumption of construction workers during coating is too large, so that the problems of labor saving and material saving need to be considered when the hopper is stably leaned on the vertical base surface, the construction process is relatively easy, the manufacturing cost is relatively low, namely, the hopper needs to limit the capacity, the upper edges of the left side surface and the right side surface incline downwards, the capacity of the hopper can be limited, the rubber asphalt waterproof coating placed at one time cannot be too much, and meanwhile, the material port formed by the front edge surfaces of the left side surface and the right side surface, make things convenient for coating unit to follow the mouth with this internal rubber asphalt waterproofing paint of hopper and coat to vertical base face on, also make the easy fall back of unnecessary rubber asphalt waterproofing paint on the coating ware in hopper body.
Further preferably, the front edges of the left and right side surfaces of the hopper body are inclined edges inclining inwards downwards, and the front orthographic projections of the left and right side surfaces are positioned in front of the front edge of the bottom surface, so that when the material opening is attached to the vertical base surface, the bottom surface is forced to incline upwards and lean against the vertical base surface.
When the front sides of the left side surface and the right side surface are arranged to enable the material port to lean against the vertical base surface, the bottom surface is forced to lean upwards and lean against the vertical base surface, namely when the vertical base surface is completely attached to the material port, the included angle beta formed between the vertical base surface and the lower surface of the bottom surface is less than 90 degrees, so that the rubber asphalt waterproof coating in the hopper body easily flows backwards along the bottom surface which is forced to lean and lean against, and is gathered at the rear part of the hopper body, so that the rubber asphalt waterproof coating in the hopper body flows out from the material port due to the fact that a constructor leans forwards or holds unstably in the coating process, and in addition, when redundant rubber asphalt waterproof coating on the coating device falls back; meanwhile, the front sides of the left side face and the right side face are arranged to enable the handle to incline upwards when the vertical base face is completely attached to the material opening, namely the height of the rear side face of the handle is smaller than that of the front side face, so that the problem that when the handle is held, the arm is lifted too high to cause that the arm is easily sore when coating is carried out, and the coating efficiency is affected is avoided.
Still further preferably, the bottom surface forced to lean upwards against the vertical base forms an angle beta of 15-65 ° with the vertical base. When beta is too large in the coating process of the vertical base surface, the upward inclination of the hopper body is too large, and when the rubber asphalt waterproof coating in the hopper body is too much, the rubber asphalt waterproof coating is easy to overflow from the rear side surface to pollute the construction environment; beta is too small, the upward inclination of the hopper body is too small, and the rubber asphalt waterproof coating is easy to leak from a material port during coating and can cause pollution. In addition, no matter whether beta is too big or too small, the effective capacity that can lead to the hopper body to hold rubber asphalt waterproof coating reduces to make the hopper body need add rubber asphalt waterproof coating repeatedly, reduce coating efficiency, so, the setting up of contained angle beta both ensures that this internal rubber asphalt waterproof coating of hopper can not spill over when the coating, also ensures that the effective capacity of hopper body is great.
Preferably, the rubber asphalt waterproof coating is a non-curing rubber asphalt waterproof coating. The non-curing rubber asphalt waterproof coating has the following advantages: (1) and (3) non-curing: the solid content is up to more than 98 percent, almost no organic substance exists, and the elastoplastic colloid is always kept in an application state; (2) excellent creep properties: the problems of cracking, flexural fatigue or advanced aging under a high stress state of the waterproof layer caused by the fact that the cracking stress of the base layer is transferred to the waterproof layer can be solved; (3) excellent adhesive properties: the adhesive can be bonded with the base surface of any material, and the viscosity of the adhesive can well seal capillary pores and cracks, so that the problem of difficult water channeling is solved; (4) excellent self-healing properties: when the waterproof layer is damaged by external force, the damage point cannot be expanded, and the creep action of the rubber asphalt waterproof coating can gradually repair the damage point; (5) excellent environmental protection performance: the paint does not contain organic solvent, has the solid content of more than 98 percent, and is an environment-friendly waterproof paint; (6) excellent elongation properties: the elongation is over 1000 percent, and the waterproof layer is not damaged due to dislocation and displacement of the base layer; (7) excellent temperature adaptability: the construction can be carried out in the environment below-10 ℃; (8) excellent chemical resistance and ageing resistance: the performance after immersion test in acid, alkali and salt medium and heat aging treatment is maintained above 90%.
Preferably, before step S1, a step of vertical basal plane cleaning and polishing is further included. Firstly, cleaning up sundries such as floating soil and the like on a base surface, secondly, shoveling off convex parts (such as cement blocks, iron nail heads and the like) of the base surface, filling concave parts of the base surface, making internal and external corners, pipe roots and crack parts of the base surface into arc shapes by using cement mortar, then, polishing the base surface to roughen the surface of a vertical base surface, thereby increasing the bonding area of the rubber asphalt waterproof coating and the base surface, enhancing the adhesive force of the rubber asphalt waterproof coating to the base surface, and finally, cleaning up floating dust and stains on the base surface.
Preferably, a step of applying a base layer treating agent is further included before step S2. The vertical base layer is usually an inorganic material layer such as a wall surface and the like, the main components of the rubber asphalt waterproof coating are organic materials such as rubber powder and asphalt, the compatibility of the rubber asphalt waterproof coating and the rubber powder is poor, the cohesive force is weak, but because the polished vertical base surface is a porous base surface, the permeability of the base layer treating agent to the porous base material is strong, and the compatibility of the organic base layer treating agent and the rubber asphalt waterproof coating is good, the binding force of the vertical base layer and the rubber asphalt waterproof coating can be effectively improved by coating a layer of the base layer treating agent on the surface of the vertical base surface; the base layer treating agent is preferably an acrylic base layer treating agent.
Further preferably, the coating thickness of the base layer treating agent is 1.0mm or less. The coated base layer treating agent is thin and uniform so as to prevent the base layer treating layer from being too thick, so that the volatilization time of liquid components in the base layer treating agent is too long and the coating period is prolonged, or the volatilization of the liquid components at the bottom layer of the base layer treating layer is insufficient so as to reduce the adhesive force between the waterproof rubber asphalt waterproof coating and a base surface, the coating thickness is preferably controlled to be below 1.0mm, and after the coating, no blank, pockmark and bubbles are left on a vertical base surface so as to avoid influencing the adhesive force between the rubber asphalt waterproof coating and the base surface; the base treatment is preferably applied by mechanical spraying.
Preferably, the push coating direction of the coating device in the step S3 is from the opening to the material opening, and is push coated on the side of the vertical base surface close to the material opening to the side of the vertical base surface far from the material opening. The rubber asphalt waterproof coating on the coating device which is just dipped with the rubber asphalt waterproof coating is the most, so the rubber asphalt waterproof coating is easy to drip, the rubber asphalt waterproof coating on the coating device is gradually reduced along with the progress of the push coating process, and the possibility of dripping the rubber asphalt waterproof coating is reduced. Push away and scribble the direction locking directly over the material mouth, push away width and material mouth width of scribbling and suit, and push away from the vertical base face one side that is close to with the material mouth and scribble to the vertical base face one side of keeping away from with the material mouth, push away under this kind of mode of scribbling, can inject the scope that rubber asphalt waterproof coating took place to drip in the material mouth and the vertical base face one side that is close to with the material mouth, reduce unnecessary rubber asphalt waterproof coating and drip and pollute the scope of vertical base face, and make in the rubber asphalt waterproof coating of drippage on vertical base face can drip back to the hopper fast, in order to avoid the rubber asphalt waterproof coating of drippage to cool off gradually because of dripping back stroke overlength of hopper, lead to the viscosity grow and can't.
Preferably, the step S3 further includes the step of applying the rubber asphalt waterproof coating while adhering the waterproof roll. The steps of coating and paving the waterproof coiled material simultaneously need two persons to cooperate to complete; the process of coating and paving the waterproof coiled material can enhance the bonding force between the rubber asphalt waterproof coating and the waterproof coiled material, so that the waterproof coiled material is easy to peel off, hollows and the like and even leak due to insufficient bonding strength or insufficient firmness in construction, and the integral waterproof effect of the vertical base surface is improved; the waterproof coiled material is preferably a thermoplastic polyolefin waterproof coiled material or an ethylene propylene diene monomer waterproof coiled material.
Compared with the prior art, the technical scheme of the invention has the beneficial effects that:
firstly, the metal material endows the hopper with excellent performances of wear resistance, heat resistance, corrosion resistance and the like, is suitable for rubber asphalt waterproof paint which needs high-temperature construction, and the hopper is not easy to be damaged and can be repeatedly used; the hopper can be used for placing a proper amount of rubber asphalt waterproof coating, so that the process that construction workers repeatedly dip and coat from a packaging barrel is avoided, the painting time is shortened, and the painting efficiency is improved;
secondly, a material port of the hopper is inclined upwards and is attached to a vertical base surface to be coated, so that the rubber asphalt waterproof coating in the hopper is concentrated to the rear part, and the rubber asphalt waterproof coating in the hopper is prevented from flowing out of the material port due to forward tilting coating of construction workers or unstable grasping caused by unstable gravity center of the hopper;
three, the coating scope is directly over the material mouth, unnecessary rubber asphalt waterproof coating will be along in the vertical base face directly over the material mouth drips the feed back fill from the material mouth, in order to avoid rubber asphalt waterproof coating to drip ground and cause the waste, and avoid the rubber asphalt waterproof coating cooling back on dripping ground, the viscosity increases and increases the clearance degree of difficulty on ground and increase, thereby can effectively maintain construction environment clean and tidy, energy-concerving and environment-protective, in addition, can also prevent that the rubber asphalt waterproof coating of high temperature from dropping to the construction worker and causing the scald on one's body, thereby improve the security of construction.

Detailed Description
In order to better understand the present invention, the following examples are further provided to illustrate the content of the present invention, but the present invention is not limited to the following examples.
Example 1
A rubberized asphalt waterproofing paint construction method, as shown in fig. 1 and 3, using a hopper as an auxiliary coating tool, the hopper comprising a hopper body 1 having a fixed capacity and a handle 2 connected to the hopper body 1, the upper part of the hopper body 1 being provided with an opening 9, and the front side being provided with a feed opening 7 for forcing the hopper to lean upward and lean on a vertical base surface 11, comprising the steps of:
s1 glue melting: heating the rubber asphalt waterproof coating 10 to the temperature of 180 ℃ and 250 ℃, and preserving heat for later use;
s2 charging: taking a proper amount of the rubber asphalt waterproof coating 10 processed in the step S1 into the hopper body 1, holding the handle 2 of the hopper by one hand, and inclining the material opening 7 upwards to lean on a vertical base surface 11 to be coated;
s3 coating: and taking the coating device with the other hand to dip a proper amount of rubber asphalt waterproof coating 10 from the opening 9 of the hopper body 1, starting the coating device from the opening 9 to the material port 7, pushing and coating the rubber asphalt waterproof coating 10 on the vertical base surface 11 right above the material port 7 until the dipped rubber asphalt waterproof coating 10 is used up, dipping a proper amount of rubber asphalt waterproof coating 10 from the opening 9 of the hopper body 1 again, repeating the pushing and coating process until the rubber asphalt waterproof coating 10 in the hopper is used up, and repeating the step S2 and the step S3 until the coating on the vertical base surface 11 is finished.
A hopper preferably made of metal; the capacity and the weight of the hopper are smaller than those of the packaging barrel, and when the material opening 7 is attached to the vertical base surface 11, the vertical base surface 11 shares part of the weight of the hopper, so that too much physical force of construction workers is not consumed in the coating process; the hopper can be used for placing a proper amount of the rubber asphalt waterproof coating 10, so that the process that construction workers repeatedly dip and coat from a packaging barrel is avoided, the brushing time is shortened, and the brushing efficiency is improved.
The rubber asphalt waterproof coating 10 has too high viscosity at normal temperature, and needs to be heated and melted to reduce the viscosity, so that the coating workability such as leveling property, film forming property and the like of the rubber asphalt waterproof coating 10 is improved, and therefore, the heating and melting process of the step S1 is convenient for uniformly coating the rubber asphalt waterproof coating 10 on a base surface; the melting temperature is easily 180 ℃ and 250 ℃, and the rubber asphalt waterproof coating 10 can be melted at the temperature, so that the rubber asphalt waterproof coating 10 can be prevented from being decomposed due to overhigh temperature, the construction viscosity can be quickly reached, and the melting time can be shortened.
In step S2, the material opening 7 of the hopper is tilted upward and attached to the vertical base surface 11 to be coated, so that the rubberized asphalt waterproofing paint 10 flows backward and gathers at the rear part of the hopper body 1, and the gravity center of the hopper is also gathered at the rear part, thereby preventing the rubberized asphalt waterproofing paint 10 in the hopper body 1 from flowing out of the material opening 7 due to forward tilting coating of a construction worker or unstable grasping of the hopper due to unstable gravity center during the coating process; the rubberized asphalt waterproof coating 10 in the hopper body 1 is concentrated to the rear part, so that the rubberized asphalt waterproof coating 10 is prevented from being wasted due to the fact that the contact area between the rubberized asphalt waterproof coating 10 and the inner surface of the hopper body 1 is too large.
In step S3, holding the hopper with one hand, holding the coating device with the other hand from the opening 9 to the material opening 7, and pushing up the vertical base surface 11 directly above the material opening 7 for coating, the coating process can be completed by coordinating the two hands, because the coating range is directly above the material opening 7, in the coating process, the redundant rubber asphalt waterproof coating 10 will drip back into the hopper body 1 from the material opening 7 along the vertical base surface 11 directly above the material opening 7, so as to prevent the rubber asphalt waterproof coating 10 from dripping onto the ground to cause waste, and avoid the rubber asphalt waterproof coating 10 dripping onto the ground from cooling down, the viscosity is increased to increase the difficulty of cleaning the ground, thereby effectively maintaining the cleanness of the construction environment, saving energy and protecting the environment, and in addition, preventing the high-temperature rubber asphalt waterproof coating 10 from falling onto the body of a constructor to cause scalding, thereby improving the safety of construction.
As shown in fig. 1, the hopper body 1 includes a bottom surface 3, a rear side surface 4, a left side surface 5, and a right side surface 6, which can form a fixed volume; the upper edges of the left side surface 5 and the right side surface 6 are inclined downwards, and the front edge of the left side surface 5, the front edge of the bottom surface 3 and the front edge of the right side surface 6 enclose a material opening 7; the handle 2 is connected with the rear side surface 4; the upper edge of the left side 5, the upper edge of the rear side 4 and the upper edge of the right side 6 enclose an opening 9. Bottom surface 3, left surface 5, right flank 6, trailing flank 4 and the preferred body coupling of handle 2 of hopper body 1 for the junction that forms each side of fixed capacity can not form the space, so rubber asphalt waterproof coating 10 of placing in the hopper body 1 can not leak outward, and handle 2 and hopper body 1 body coupling, makes the two connect more stably, thereby handle 2 holds more firmly, and in addition, the integral type structure can also simplify the technology of machine-shaping. In order to make the holding of the hopper more labor-saving in the coating process, the handle 2 is connected with the rear side surface 4, namely the handle 2 is close to the gravity center of the hopper containing the rubber asphalt waterproof coating 10.
During coating, in order to prevent the rubber asphalt waterproof coating material 10 from leaking out of the material opening 7, the rubber asphalt waterproof coating material 10 is gathered to the rear part of the hopper body 1, in other words, the front part of the hopper body 1 does not play a role of containing the rubber asphalt waterproof coating material 10, namely, the front part of the hopper body 1 mainly plays a role of stably leaning on the vertical base surface 11, and if the capacity of the hopper is too large, the labor consumption of construction workers during coating is too large, so that the problems of labor saving and material saving need to be considered when the hopper stably leans on the vertical base surface 11, the construction process is relatively easy, the manufacturing cost is relatively low, namely, the hopper needs to limit the capacity, the upper sides of the left side surface 5 and the right side surface 6 incline downwards, the capacity of the hopper can be limited, the rubber asphalt waterproof coating material 10 placed at one time cannot be too much, and simultaneously, the 7 formed by the front side surfaces of the left side surface 5 and the right side surface 6 and the front, the rubber asphalt waterproof coating 10 in the hopper body 1 is conveniently coated on the vertical base surface 11 from the material opening 7 by the coating device, and the redundant rubber asphalt waterproof coating 10 on the coater is easily fallen back into the hopper body 1.
Specifically, as shown in fig. 1 and 2, the front edges of the left and right sides of the hopper body 1 are inclined edges 8 which incline inwards downwards, and the front orthographic projections of the left and right sides are positioned in front of the front edge of the bottom surface 3, so that when the material opening 7 abuts against the vertical base surface 11, the bottom surface 3 is forced to incline upwards and lean against the vertical base surface 11. When the material opening 7 leans against the vertical base surface 11, the bottom surface 3 is forced to lean upwards and lean against the vertical base surface 11, namely when the vertical base surface 11 is completely attached to the material opening 7, an included angle beta formed by the vertical base surface 11 and the lower surface of the bottom surface 3 is less than 90 degrees, so that the rubber asphalt waterproof coating 10 in the hopper body 1 can easily flow backwards along the bottom surface 3 which is forced to lean upwards and is gathered at the rear part of the hopper body 1, and in the coating process, a constructor can prevent the rubber asphalt waterproof coating 10 in the hopper body 1 from flowing out of the material opening 7 due to forward leaning or unstable holding, and in addition, when the redundant rubber asphalt waterproof coating 10 on a coating device falls back, the redundant rubber asphalt waterproof coating can also quickly flow to the rear part of the hopper body 1; meanwhile, the front sides of the left side surface and the right side surface are arranged to ensure that when the vertical base surface 11 is completely attached to the material opening 7, the handle 2 is also inclined upwards, namely the height of the rear side surface 4 of the handle 2 is smaller than that of the front side surface, so that the problem that when the handle 2 is held, the arm is lifted too high to cause that the arm is easy to ache during coating and the coating efficiency is influenced is avoided.
More specifically, as shown in fig. 1 and 3, the bottom surface 3 which is forced to lean upwards and obliquely against the vertical base surface 11 forms an included angle beta of 15-65 ° with the vertical base surface 11. In the process of coating the vertical base surface 11, beta is too large, the upward inclination of the hopper body 1 is too large, and when the rubber asphalt waterproof coating 10 in the hopper body 1 is too large, the rubber asphalt waterproof coating 10 is easy to overflow from the rear side surface 4, so that the construction environment is polluted; beta is too small, the upward inclination of the hopper body 1 is too small, and the rubber asphalt waterproof coating 10 is easy to leak from the material opening 7 during coating, which also causes pollution. In addition, no matter whether beta is too large or too small, the effective capacity that hopper body 1 can hold rubber asphalt waterproof coating 10 is reduced, so that rubber asphalt waterproof coating 10 needs to be repeatedly added to hopper body 1, the coating efficiency is reduced, and therefore, the arrangement of included angle beta ensures that rubber asphalt waterproof coating 10 in hopper body 1 cannot overflow during coating and that the effective capacity of hopper body 1 is large.
Wherein, the rubber asphalt waterproof coating 10 is a non-curing rubber asphalt waterproof coating 10. The non-curable rubber asphalt waterproof coating 10 has the following advantages: (1) and (3) non-curing: the solid content is up to more than 98 percent, almost no organic substance exists, and the elastoplastic colloid is always kept in an application state; (2) excellent creep properties: the problems of cracking, flexural fatigue or advanced aging under a high stress state of the waterproof layer caused by the fact that the cracking stress of the base layer is transferred to the waterproof layer can be solved; (3) excellent adhesive properties: the adhesive can be bonded with the base surface of any material, and the viscosity of the adhesive can well seal capillary pores and cracks, so that the problem of difficult water channeling is solved; (4) excellent self-healing properties: when the waterproof layer is damaged by external force, the damage point cannot be expanded, and the creep action of the rubber asphalt waterproof coating 10 can gradually repair the damage point; (5) excellent environmental protection performance: the paint does not contain organic solvent, has the solid content of more than 98 percent, and is an environment-friendly waterproof paint; (6) excellent elongation properties: the elongation is over 1000 percent, and the waterproof layer is not damaged due to dislocation and displacement of the base layer; (7) excellent temperature adaptability: the construction can be carried out in the environment below-10 ℃; (8) excellent chemical resistance and ageing resistance: the performance after the immersion test in acid, alkali and salt media and the thermal aging treatment is kept above 90 percent; the non-curing rubber asphalt waterproof coating 10 used in the invention is the non-curing rubber asphalt waterproof coating 10 which meets the building material industry standard (standard number: JC/T2428-.
Before step S1, the method further includes the steps of cleaning and polishing the vertical base surface 11. Firstly, cleaning up sundries such as floating soil on a base surface, secondly, shoveling off convex parts (such as cement blocks, iron nail heads and the like) of the base surface, filling concave parts of the base surface, making internal and external corners, pipe roots and crack parts of the base surface into arc shapes by using cement mortar, then, polishing the base surface to roughen the surface of a vertical base surface 11, thereby increasing the bonding area of the rubber asphalt waterproof coating 10 and the base surface, enhancing the adhesive force of the rubber asphalt waterproof coating 10 to the base surface, and finally, cleaning up floating dust and stains on the base surface.
Wherein, before step S2, a step of applying a layer of base layer treating agent is further included. The vertical base layer is usually an inorganic material layer such as a wall surface, the main components of the rubber asphalt waterproof coating 10 are organic materials such as rubber powder and asphalt, the compatibility of the rubber asphalt waterproof coating and the rubber powder is poor, the cohesive force is weak, but because the polished vertical base surface 11 is a porous base surface, the permeability of the base layer treating agent to the porous base material is strong, and the compatibility of the organic base layer treating agent and the rubber asphalt waterproof coating 10 is good, the adhesion force of the vertical base layer and the rubber asphalt waterproof coating 10 can be effectively improved by coating a layer of the base layer treating agent on the surface of the vertical base surface 11; the base layer treating agent is preferably an acrylic base layer treating agent.
Specifically, the coating thickness of the base layer treating agent is 1.0mm or less. The base layer treating agent is thin and uniform so as to prevent the base layer treating layer from being too thick, so that the volatilization time of liquid components in the base layer treating agent is too long and the coating period is prolonged, or the volatilization of the liquid components at the bottom layer of the base layer treating layer is insufficient so as to reduce the adhesive force between the waterproof rubber asphalt waterproof coating 10 and a base surface, the coating thickness is preferably controlled to be below 1.0mm, and after the base layer treating agent is coated, no blank, pockmarks and bubbles are left on the vertical base surface 11 so as to avoid influencing the adhesive force between the rubber asphalt waterproof coating 10 and the base surface; the base treatment is preferably applied by mechanical spraying.
As shown in fig. 1 and 3, the coating device in step S3 has a push-coating direction from the opening 9 to the material opening 7, and pushes-coats the side of the vertical base surface 11 close to the material opening 7 to the side of the vertical base surface 11 far from the material opening 7. The rubber asphalt waterproofing paint 10 on the coating device which has just been dipped with the rubber asphalt waterproofing paint 10 is the most, and at this time, the rubber asphalt waterproofing paint 10 is most likely to drip, and as the push coating process proceeds, the rubber asphalt waterproofing paint 10 on the coating device is gradually reduced, and the possibility of the rubber asphalt waterproofing paint 10 dripping is also reduced. The direction locking of will pushing away to scribble is directly over material mouth 7, the width that pushes away to scribble suits with material mouth 7 width, and push away from the vertical base face 11 one side that is close to with material mouth 7 and scribble to the vertical base face 11 one side of keeping away from with material mouth 7, under this kind of push away scribbles the mode, can inject the scope that rubber asphalt waterproof coating 10 takes place to drip in material mouth 7 and the vertical base face 11 one side that is close to with material mouth 7, reduce unnecessary rubber asphalt waterproof coating 10 and drip and pollute the scope of vertical base face 11, and make rubber asphalt waterproof coating 10 that drips on vertical base face 11 can drip back to the hopper fast in, so that the rubber asphalt waterproof coating 10 that drips cools off gradually because of the return stroke overlength that drips back to the hopper, lead to the viscosity grow and can's in can't dripping.
Wherein, in the step S3, the method further includes the step of spreading the waterproof roll while applying the rubber asphalt waterproof coating 10. The steps of coating and paving the waterproof coiled material simultaneously need two persons to cooperate to complete; the process of coating and paving the waterproof roll can enhance the bonding force between the rubber asphalt waterproof coating 10 and the waterproof roll, so that the waterproof roll is easy to peel off, hollows and the like due to insufficient bonding strength or insufficient firmness in construction, and even leaks, thereby improving the overall waterproof effect of the vertical base surface 11; the waterproof coiled material is preferably a thermoplastic polyolefin waterproof coiled material or an ethylene propylene diene monomer waterproof coiled material.
