Abstract
The invention discloses elastic coating used for repairing the cracking of the exterior thermal insulation layer of an exterior wall, which aims to solve the problems that the priror cracking of the exterior thermal insulation layer of an exterior wall is repaired by the constructors through the methods such as reinforcing and controlling the constructing quality and the like, but the effect is not ideal. Each component and the weight percentage of the elastic coating are as follows: water accounting for 15 percent to 20 percent, LD super hydrophobic interface agent accounting for 0.15 percent to 0.25 percent, fluorous leveling agent accounting for 0.15 percent to 0.2 percent, dispersing agent accounting for 0.2 percent to 0.5 percent, antifoaming agent accounting for 0.2 percent to 0.4 percent, propylene glycol accounting for 2.0 percent, white titanium pigment accounting for 20 percent to 23 percent, quarried calcium carbonate accounting for 7 percent to 9 percent, benzene dibutyl acid dibutyl ester accounting for 5 percent to 7 percent, modified pure acrylic elastic emulsion accounting for 40 percent to 45 percent, lauryl alcohol ester accounting for 0.8 percent to 1.2 percent, anticorrosion agent accounting for 0.1 percent to 0.2 percent and thickening agent accounting for 0.6 percent to 0.9 percent, and the surplus is color paste. The elastic coating can ensure that the function of the exterior thermal insulation layer of the exterior wall can be exerted normally.
Description
Technical field
The present invention relates to paint field, specifically a kind of ultra low temperature elastic paint that is used for renovating external thermal insulation dehiscence of exterior wall.
Background technology
China's building energy consumption accounts for more than 40% of total energy consumption, and country has proposed concrete requirement to building energy conservation, has formulated relevant policy and technological standard, and increasing building has adopted external wall insulating layer.At present, domestic external wall insulating layer has adopted organic materials mostly.Owing to the reasons such as contraction of construction quality, material self have caused a large amount of external wall insulating layers cracking phenomena to occur, and the cracking of external thermal insulation can cause water regain to increase, and heat-insulating property descends; Cracking also can cause the blast of external thermal insulation and deadweight to strengthen simultaneously, and external thermal insulation is easily come off, and jeopardizes personnel safety.
At the cracking of external wall insulating layer, the workmen adopts methods such as reinforcing (as using grid cloth, increasing holdfast etc.), control construction quality, but effect is unsatisfactory.
Summary of the invention
Technical problem to be solved by this invention is to overcome the defective that above-mentioned prior art exists, and a kind of ultra low temperature elastic paint that is used for renovating external thermal insulation dehiscence of exterior wall is provided.
For this reason, the technical solution used in the present invention is as follows: ultra low temperature elastic paint, its each component and weight percent thereof are as follows: water 15%-20%, LD super-hydrophobicity interfacial agents 0.15%-0.25%, fluorine-containing flow agent 0.15%-0.2%, dispersion agent 0.2%-0.5%, defoamer 0.2%-0.4%, propylene glycol 2.0%, titanium dioxide 20%-23%, water-ground limestone 7%-9%, adjacent benzene two butyric acid dibutylester 5%-7%, modification elastic pure acrylic acid emulsion 40%-45%, ten diester alcohol 0.8%-1.2%, sanitas 0.1%-0.2%, thickening material 0.6-0.9%, surplus is a mill base.
The present invention is a base-material by the elastic pure acrylic acid emulsion of modification, adds alkaline conditioner, nano assistant, dispersion agent, and auxiliary agents such as pigment, filler, mill base, mould inhibitor mix.The effect of water is a dispersion agent, i.e. dispersion medium; The effect of fluorine-containing flow agent is the flowability of increase system; The effect of dispersion agent is that color stuffing is uniformly dispersed in whole system; Titanium dioxide and water-ground limestone are to use as face, filler, increase the hiding rare and the appearance tactile impression of coating; The main effect of modification pure acrylate elastic emulsion is the caking agent as coating, and total system is mediated together; Ten diester alcohol (Texanol) and propylene glycol are film coalescence aid, promote the coating film forming; The main effect of defoamer is the bubble of eliminating in the coating, avoids holiday; Sanitas mainly is to prevent that coating from going mouldy in storage process; Thickening material mainly is to improve dope viscosity, and workability is provided; LD super-hydrophobicity interfacial agents is the multifunctional nano auxiliary agent, mainly is contamination resistance and the ageing resistance that improves coating; The increase system that the act as plasticity of adjacent benzene two butyric acid dibutylesters.
Above-mentioned ultra low temperature elastic paint, LD super-hydrophobicity interfacial agents are a kind of organosilicon materials (commercially available prod, manufacturer is Zhejiang Academy of Building Research ﹠ Design Redya. Ltd.) of nano modification; Thickening material is selected thickening material TT-935 and thickening material TT-615 for use.
The present invention has overcome poor, the deficiencies such as low temperature elasticity is bad, easy cracking of poor water resistance, the water-repellancy of traditional elastic coating, have the following advantages: excellent water resistance, contamination resistance energy, good low temperature elasticity, can significantly improve the waterproof of external thermal insulation, anti-contamination, resistance to cleavage; Prevent and cover because the cracklin that causes of external wall insulating layer, guaranteed the skin surface energy complete surface that keeps clean muchly, also guaranteed the normal performance of external wall outer insulation layer function; Coating is nonpoisonous and tasteless pollution-free, easy construction, and implement is also very convenient.
The invention will be further described below in conjunction with embodiment.
