Description
Technical field
The present invention relates to building material technical field more particularly to a kind of insulation putty for architectural exterior wall.
Background technology
Putty is a kind of decoration type material of smooth surface of wall, is a kind of thick slurry coating material, and being must not before coating paints
A kind of product that can lack.Painting is imposed on priming paint or is directly applied and imposes on object, rugged on coated article surface to remove
Defect.
Putty needs are bonded together with wall securely, while coating being made to be easy to cover with paint, lacquer, colour wash, etc. in the above again.Therefore, greasy
Sub- essence is a kind of interface treating agent, should be solved and wall connecting, and is solved compatible with coating.Wall is a complicated base
Layer, it may be possible to brick wall, cob wall, concrete walls and all kinds of walls.For these walls although form differs, composition is with inorganic
Material based on silicate.Enhance putty and its adhesion strength, needs to mix cement in putty and sand, putty connect with water
The silicate cement compound formed after touch has gelling, and similar to base material physical property, thus can be bonded on metope play it is flat
Whole effect.
Authorization Notice No. CN 1300264C disclose " a kind of aqueous putty powder ", by cement, powder lime carbonate and cellulose
Composition, cellulose can be methylcellulose, hydroxypropyl cellulose or carboxymethyl cellulose, and the powder of lacquer putty for use on is with water mix at mortar
Or rock ballast slurry, then smearing makes wall leveling on metope, the wall facing that this powder of lacquer putty for use on is smeared is easy to crack, fall off, change colour and
Durability is poor.
Publication No. CN101434762A is disclosed " a kind of shale heat-preserving heat-insulating wall putty ", including following mass parts at
Point：80-90 parts of white cement, clean 75-85 parts of shale sand, 13-16 parts of slate flour, 1.4-1.7 parts of redispersable latex powder, powder
0.6-0.7 parts of shape organosilicon, 4.5-5 parts of fiber, 68-77 parts of water, 44-50 parts of latex solution, 2.3-2.7 parts of cellulose ether, wetting
0.6-0.7 parts of agent, 0.7-0.8 parts of antifoaming agent, 1.5-1.7 parts of microbicide.The shale heat-preserving heat-insulating putty, which has, to be bonded by force
Degree is high, weatherability is strong, insulation function, but flexible poor, and frequent cracking phenomenon drastically influences the painting of later stage coating
Swiped through journey is normally carried out.
Invention content
In order to solve flexible poor, the cracking problem during use of putty in the prior art, the purpose of the present invention is
A kind of insulation putty for architectural exterior wall is provided.
To achieve the goals above, the present invention adopts the following technical scheme that：A kind of insulation putty for architectural exterior wall, by A and B two parts
Composition, the part A includes the following component of parts by weight：56-74 parts of white cement, 20-30 parts of acrylate monomers,
8-10 parts of powdered whiting, 6-13 parts of dispersant, 40-50 parts of water, 4-7 parts of hollow glass micropearl, 0.5-1 parts of hydroxyl
Propyl methocel, the part B are isocyanates, and the mass ratio of the A and B are 5:1-8:1.
Hollow glass micropearl is structure that is hollow, having rigid shell, and the hollow structure coefficient of heat conduction is low, in the coating of formation
It is middle to constitute adiabatic cavity, play thermal insulation function.
The used in amounts of hollow glass micropearl will be controlled strictly, and when the dosage of hollow glass micropearl is smaller, hollow glass is micro-
The heat insulation unobvious of pearl；When the dosage of hollow glass micropearl is larger, it is coarse to lead to be formed by coating surface, durability
It is deteriorated with contamination.
Preferably, the dispersant is the BYK191 dispersants of Bi Ke.
Preferably, the grain size of the hollow glass micropearl is 50-100 μm.
Preferably, the part A further includes the following component of parts by weight：0.1-0.2 parts of pH adjusting agent, 0.1-
The levelling agent of 0.15 part of antifoaming agent and 0.4-0.5 part.
Preferably, the pH adjusting agent is the Dow Chemical Company pH adjusting agent AMP-95.
Preferably, the antifoaming agent is dimethyl silicone polymer.
Preferably, the levelling agent is Nuo Pu sections thickening leveling agent 612.
Before use, part B is added in part A, the isocyanates in acrylate monomers and part B in part A
It reacts and generates reticulated polyurethane structure, increase the compactness of formed film, improve the water resistance of film；Gather simultaneously
Urethane structural glass temperature is low, far below the environment temperature used so that the soft film coating being formed by avoids film cracking
The generation of phenomenon improves the crack resistance of film.
Compared with prior art, the advantageous effect that the present invention realizes：Insulation putty for architectural exterior wall of the present invention is by white cement and hydroxypropyl
Ylmethyl cellulose is combined, and improves the caking property between putty and cavity, white cement is main binder, hydroxypropyl methyl cellulose
For additional adhesive, white cement is used in compounding with hydroxypropyl methyl cellulose, improves phase of the white cement with other organic components
Capacitive；Hollow glass micropearl is added in insulation putty for architectural exterior wall of the present invention, improves the heat preservation and insulation of formed film；The present invention
Insulation putty for architectural exterior wall uses two-component, and the isocyanates in acrylate monomers and part B in part A reacts generation
Reticulated polyurethane structure improves the compactness for being formed by film, improves water-fast, the anti-pollution characteristic of film；Polyurethane simultaneously
Structural glass temperature is low so that soft film coating avoids the generation of cracking phenomena；The present invention is compounded using multiple components,
The excellent insulation putty for architectural exterior wall of heat-insulation and heat-preservation, water resistance, crack resistance is obtained, the scope of application of putty is expanded.
