Abstract
The invention discloses the construction method of a kind of water-based uncured coating and coiled material composite waterproof system, comprise the following steps：S1：Water-based uncured coating is sprayed on substrate layer；S2：Waterproof roll layer is pasted in S1 coating surfaces.The construction method of the water-based uncured coating coiled material composite waterproof system of the present invention sprays water-based uncured coating in substrate surface first, the waterproof layer of integral seamless is formed in substrate surface, then the adhesive property of the water-based uncured coating is utilized, waterproof roll is directly bonded in the upper end of water-based uncured coating, to increase the rigidity of waterproof system, compared with prior art, work progress is without heating, dry and wet degree no requirement (NR) to construction surface, cold construction and rainy day construction can be achieved.
Description
Technical field
The present invention relates to waterproof construction technology field, and in particular to a kind of water-based uncured coating and coiled material composite water-proof system
The construction method of system.
Background technology
The water-based uncured coating of uncured rubber asphalt and coating have good adhesion, extensibility, self-healing property, low temperature
It is flexible, jointless construction can be realized in waterproof construction, is a kind of new asphalt waterproofing material.In existing roofing, underground
Waterproof material, buildings waterproof construction in the related specifications of waterproofing work, code to more than, construction method, the acceptance of work have
Relatively clearly provide.The construction of a kind of uncured rubber-asphalt coating and coiled material complex waterproof layer is disclosed in CN103465540A
Method, its content are included after uncured rubber-asphalt coating is heated into set point of temperature, are existed by the method construction for scratching, spraying
The surface of basic unit, in the waterproof roll layer that surface mount and the uncured rubber-asphalt coating of hot coating mix.This document is said
Referred in bright book, technical problem to be solved is self-adhesive coiled material waterproof layer and basic unit in wet-laying engineering method of the prior art
The channeling water and drainage gone between (or structure sheaf) into " Sandwich biscuit type ", moreover it is possible to which solution is led because worker's constructing operation is lack of standardization
The waterproof layer hollowing phenomenon of cause.Uncured rubber-asphalt coating in such scheme needs to be coated with after heating, in construction environment
Solvent volatile quantity is larger, to fire-fighting requirements height；Substrate surface must be dried, and can not be constructed under wet condition.
Improved technical scheme also includes connecing waterproof roll using melt viscosity in the prior art, but the use of PUR is same
Sample needs to heat, and clean-up performance to waterproof construction face and degree of drying require higher, and working procedure is cumbersome.
In addition, although coiled material seam crossing passes through much time using, seam crossing easily seeps water through water-proofing treatment
Phenomenon, so as to further influence the bonding stability between coiled material and base material.
The content of the invention
It is an object of the invention to overcome defect present in prior art, there is provided a kind of to construction substrate and environmental requirement
The construction method of low water-based uncured coating and coiled material composite waterproof system.
To realize above-mentioned technique effect, the technical scheme is that：A kind of water-based uncured coating is compound anti-with coiled material
The construction method of water system, it is characterised in that comprise the following steps：
S1：Water-based uncured coating is sprayed on substrate layer；
S2：Waterproof roll layer is pasted in S1 coating surfaces.
In order to optimize the compatibility of water-based uncured coating and coiled material, preferable technical scheme is that waterproof roll layer is certainly
The polymer modified waterproof roll of adhesive aggregation, SBS/APP modified asphalt waterproof coiled materials and the non-bituminous base waterproof roll of macromolecule.
Further preferred technical scheme is that the material of the non-bituminous base waterproof roll of macromolecule is TPO, HDPE, PVC, three
First EP rubbers.
Preferable technical scheme is that the main composition of water-based uncured coating is：Anion rubber elastomer modified emulsifying
Pitch, modified resin emulsion, filler, auxiliary agent, wherein auxiliary agent be selected from defoamer, dispersant, stabilizer, vulcanizing agent, age resistor,
Combination more than one or both of wetting agent and antifreezing agent, water-based uncured coating is using exterior mixing two-component spray gun with promoting
Solidifying agent solution sprays simultaneously.Coagulant and water-based uncured coating are sprayed simultaneously, it is ensured that two kinds of solution are dropping down onto spraying
Mix in front, promote demulsification to accelerate de-emulsification speed by inside dope layer, it is above-mentioned anti-under rainy day or cryogenic conditions
Water construction can be also normally carried out, in addition, the phenomenon for being applied directly to cause in coating shower nozzle to block coagulant can be avoided.
Preferable technical scheme is that the key component of water-based uncured coating is：Anion rubber elastomer modified emulsifying
70~80 parts of pitch, 8~13 parts of the modified resin emulsion that solid content is 42~70%, 5~20 parts of filler, auxiliary agent 0.005~12
Part.With cationic emulsified bitumen de-emulsification speed soon compared with, anionic emulsified bitumen is relatively slow, but has stronger bonding force,
The demulsification process of coating can realize the wetting and infiltration with waterproof roll, and waterproof roll can directly be bonded in water-based uncured coating
Surface, Quick cross-linking occurs between two layers, so as to ensure larger adhesive strength between two layers of waterproof system.
Preferable technical scheme is that the composition and parts by weight of anion rubber elastomer modified emulsifying asphalt are：Matrix
