Description
Technical field
The insulation that the present invention relates to external wall and roofing is handled material and technology, particularly a kind of thermal insulation mortar and based on the external wall construction technology of this thermal insulation mortar.
Background technology
Applying of external wall outer insulation engineering plays a positive role to the practicable of energy-saving and emission-reduction policy in recent years.But also exposed the fire safety of certain problem, particularly lagging material in the engineering construction process, especially the fire safety problem in the construction of Highrise buildings heat insulating work is more outstanding.Betide Shanghai and Shenyang big fire in 2010, make Chinese Government to the fire resistance of lagging material, rise to the A level, and formulated strict declaration and acceptance process for this reason, this just uses for the engineering of inorganic non-combustible thermal insulation mortar unprecedented opportunity is provided.
In existing A level lagging material, having only rock wool, glass wool, inorganic heat insulation mortar is the product that meets the fire-protection rating of regulations for fire fighting.Existing inorganic heat insulation mortar main technological route is to adopt the light skeletal of inorganic coagulation material, suitable proportion, and doses admixtures such as redispersable latex powder, ether of cellulose, mixes the back packing.Most inorganic heat insulation mortars adopt the single-component package form, and the minority product is packed light skeletal separately, adopt the bi-component package form.Gelling material in the inorganic heat insulation mortar is main component with cement, adds materials such as a spot of flyash, ground slag powder.Light skeletal mainly comprises porousness mineral grains such as glass bead, pearlstone.The inner air content in existing inorganic coagulation material slurry construction back is low, and water resistance is undesirable, thereby heat-insulating property descends greatly after causing inorganic heat insulation mortar to meet water.
Existing thermal insulation mortar adopts artificial plastering method construction, and speed of application is slow on the one hand, and long construction period is to the requirement height of workman's technology.On the other hand owing to adopt the artificial construction, need to increase the workability of mortar, and the approach of increase workability, often adopt and improve the gelling material ratio, reduce the method for light skeletal ratio, certainly will improve the thermal conductivity of thermal insulation mortar, and the raising of the thermal conductivity of thermal insulation mortar, certainly will influence the heat-insulating property of buildings, thereby reduce building energy conservation efficient.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of thermal insulation mortar is provided, it can effectively improve heat-insulating property and the water resistance of thermal insulation mortar.
The present invention solves the problems of the technologies described above and takes following technical scheme to realize:
A kind of thermal insulation mortar is characterized in that: it is made of following components in weight percentage:
Ordinary Portland cement 40-58%;
Glass bead/pearlstone 40-58%;
Water-holding agent 0.3-1%;
Air entrapment agent 0.005-0.02%;
Anti-fall dose of 0.02-0.05%;
Hydrophober 0.2-1%;
Suds-stabilizing agent 0.1-0.3%;
Redispersable latex powder 1-2%.
The present invention also aims to provide a kind of external wall construction technology based on thermal insulation mortar, it can improve the thermal insulation mortar operating efficiency, reduces gel material content in the thermal insulation mortar.
The present invention solves the problems of the technologies described above and takes following technical scheme to realize:
A kind of external wall construction technology based on described thermal insulation mortar, it is characterized in that: processing step is:
(1). the preparation compound:
According to thermal insulation mortar: water is 1: 0.8～1 ratio, thermal insulation mortar is added water mix;
(2). adopt the mortar spraying equipment that compound is sprayed into skin;
(3). treat to carry out after thermal insulation mortar hardens the spraying application of next layer thermal insulation mortar, spray altogether three times that each coating thickness is 15～25mm;
(4). the second time thermal insulation mortar spraying application finish and thermal insulation mortar sclerosis after, set up one deck hot-galvanized steel silk screen sheet enhancement layer, adopt the insulation dedicated expansion screw bolt with hot-galvanized steel silk screen sheet and basic unit's body of wall fixation, carry out follow-up thermal insulation mortar spraying application then;
(5). when thermal insulation mortar construction thickness reaches design thickness, that the thermal insulation mortar surface is floating with floating instrument.
Advantage of the present invention and positively effect are:
1. thermal insulation mortar of the present invention is gelling material with the ordinary Portland cement, is light skeletal with glass bead, pearlstone etc., and adds water-holding agent, air entrapment agent, anti-fall dose, hydrophober, suds-stabilizing agent, redispersable latex powder.This thermal insulation mortar is main component with the inorganic materials, and combustionproperty reaches the A grade standard, has heat insulation effect preferably simultaneously.Owing to added air entrapment agent in the thermal insulation mortar prescription, exist a large amount of pores in the inorganic coagulation material slurry, improved the heat-insulating property of inorganic coagulation material slurry, inorganic coagulation material has not only played the effect that light skeletal is bonded to an integral body like this, and the inorganic coagulation material slurry of vesicular structure itself also has insulation effect.Thereby avoided the single heat-insulating property of only improving material by the addition of control light skeletal.The heat insulation effect of thermal insulation mortar is further enhanced.The adding of hydrophober has improved the water resistance of thermal insulation mortar, has overcome traditional thermal insulation mortar back phenomenon of reducing greatly of heat insulation effect of making moist.
2. thermal insulation mortar of the present invention is by adjusting its proportioning and admixture (water) addition content, make the workability of this material to improve, this material can adopt the automatic arc spraying construction technology, when adopting the mortar spraying equipment to be sprayed into metope, have good adhesivity, do not produce the phenomenon of landing, changed traditional manual plastering technique, improve speed of application greatly, reduced the waste of material simultaneously.
3. construction technology of the present invention installs hot-galvanized steel silk screen sheet enhancement layer additional after second layer thermal insulation mortar sclerosis, is connected with the basic unit integrality of wall in the time of can improving thermal insulation mortar construction thickness and surpass 40mm.
4. thermal insulation mortar of the present invention is added with air entrapment agent and hydrophober, and reasonable ratio can be so that the inorganic coagulation material slurry has comparatively ideal waterproof effect existing under the prerequisite of a large amount of pores.Based on thermal insulation mortar of the present invention, can realize the automatic arc spraying construction, thereby significantly improve speed of application, reduce gel material content in the thermal insulation mortar, reduce cost, be a kind of heat preservation construction technology that has than high innovation character, have good popularizing application prospect.
