Description
Technical field
The invention belongs to the exterior wall heat-insulating paint preparing technical field, particularly relate to a kind of exterior-wall heat insulation anti-cracking waterproof coating anti-fissuring agent and preparation method thereof.
Background technology
At present, traditional brick and tile building material owing to strive ground with the farmland, expends the energy, and it is excessive conduct oneself with dignity, the increase transport power, thermal insulation differences etc. are former thereby be restricted, generation and be frame light structure and steel framed structure.These structures all there is individual insulation problem,, the problem of a thickness of wall body is arranged also even brick mix structure will reach certain heat insulation effect.In this case, thermal insulation coatings arises at the historic moment, use thermal insulation coatings, take strict operational procedure, reach same heat insulation effect, can reduce thickness of wall body, be equally applicable to the insulation that frame gently reaches the steel framed structure body of wall, so not only reduced the buildings deadweight, and saved the energy, transport power and land resources, therefore had a extensive future.Thermal insulation coatings development in recent years is very fast, and application example is also a lot, but after wall is used on the thermal insulation coatings, the different crackle of degree all occurs.This has influenced the waterproof and the heat-insulating property of coating to a certain extent.
Summary of the invention
The present invention provides a kind of exterior-wall heat insulation anti-cracking waterproof coating anti-fissuring agent and preparation method thereof for solving the technical problem that exists in the known technology.
After adopting the anticracking grout and flexible putty drying of anti-fissuring agent of the present invention preparation, expose to the weather and do not split, thereby guaranteed the waterproof and the heat-insulating property of coating through the several months.
Anti-fissuring agent of the present invention is to adopt elastic pure acrylic acid emulsion, the filamentary material that glass microballon is different with length, Young's modulus is different that cooperates wetting agent, frostproofer, water-holding agent, defoamer, sanitas, different grain warps, a kind of sizing material of making by dispersed with stirring.
Adopt elastic pure acrylic acid emulsion, can be made into anti-fissuring agent, and then can be mixed with prolonged anticracking grout that does not split and flexible putty with excellent resistance to cleavage.
The prescription batching of anti-fissuring agent is to have utilized glass microballon before and after solidifying, and the principle of constancy of volume is to reduce the volumetric shrinkage of anticracking grout and flexible putty.Utilize the length difference, the filamentary material that Young's modulus is different, and the reticulated structure that forms plays the effect of stiffening web, avoids cracking with the pull resistance that strengthens anticracking grout and flexible putty, has also reduced its volumetric shrinkage.Certainly the elastic pure acrylic acid emulsion as binder main body has certain elasticity owing to after the film forming, and the crackle that can bear certain deformation also is the major reason that prevents that coating from cracking.Methylcellulose gum, ethylene glycol can prevent as water-holding agent that the rapid evaporation of moisture content is existing and volume that produce acutely shrinks, and can prevent that also anticracking grout and flexible putty from cracking.
The technical scheme that exterior-wall heat insulation anti-cracking waterproof coating of the present invention is taked with anti-fissuring agent is:
Exterior-wall heat insulation anti-cracking waterproof coating anti-fissuring agent, form by water, film forming material, wetting agent, frostproofer, water-holding agent, defoamer, sanitas, the weight part of anti-fissuring agent consists of: water 10-30, elastic pure acrylic acid emulsion 20-50, OP-100.1-0.4, ethylene glycol 0.5-5, defoamer 0.05-0.2, sanitas 0.01-0.2, methylcellulose gum 0.01-1.5,40-80 order glass microballon 10-40,80-120 order glass microballon 10-40,0.5-2mm glass fibre 0.1-1,2-4mm glass fibre 0.2-1.5,0.5-5mm xylon 0.1-1.5.
Exterior-wall heat insulation anti-cracking waterproof coating of the present invention can also adopt following technical measures with anti-fissuring agent:
Described exterior-wall heat insulation anti-cracking waterproof coating anti-fissuring agent, its weight part consists of: water 15-25, elastic pure acrylic acid emulsion 20-40, OP-10 0.1-0.2, ethylene glycol 1-3, defoamer 0.1-0.15, sanitas 0.01-0.1, methylcellulose gum 0.1-1,40-80 order glass microballon 20-35,80-120 order glass microballon 15-35,0.5-2mm glass fibre 0.3-0.6,2-4mm glass fibre 0.5-1.0,0.5-5mm xylon 0.5-1.0.
Exterior-wall heat insulation anti-cracking waterproof coating of the present invention adopts following technical scheme with the preparation method of anti-fissuring agent:
The exterior-wall heat insulation anti-cracking waterproof coating preparation method of anti-fissuring agent comprises following technological process:
(1) preparation of methocel solution
In stirred vessel, add entry, under agitation condition, add methylcellulose gum, until all being dissolved into sub-translucent solution;
(2) preparation of anti-fissuring agent
Under agitation condition, in container, add entry and elastic pure acrylic acid emulsion, add OP-10, ethylene glycol, defoamer, sanitas, methocel solution, 40-80 order glass microballon, 80-120 order glass microballon, 0.5-2mm glass fibre, 2-4mm glass fibre, 0.5-5mm xylon then, stir and make anti-fissuring agent.
Exterior-wall heat insulation anti-cracking waterproof coating of the present invention can also adopt following technical measures with the preparation method of anti-fissuring agent:
The described exterior-wall heat insulation anti-cracking waterproof coating preparation method of anti-fissuring agent comprises following technological process:
