specific Embodiment approach

[0021] Get 38 kilograms of hydroxyl acrylic resin, 0.2 kilogram of anti-settling agent (organic bentonite), 10 kilograms of organic solvent (ethyl acetate), 1.8 kilograms of auxiliary agent (dispersant efka-4050, defoamer BYK141 or their mixture), pigment ( Titanium dioxide) 30 kilograms, talcum powder 25 kilograms. Take 16 kg of the adduct of toluene diisocyanate (TDI) and trimethylolpropane, 4 kg of butyl acetate, and then pour it into a high-speed disperser and mix evenly to meet the ratio of component A and component B at 5:1 Mix and match. During construction, an appropriate amount of solvent can be added to adjust the viscosity according to specific conditions.

[0022] The painting process of the present invention requires that the synthetic resin imitation curtain wall middle layer paint be adjusted and constructed by spraying or brushing.

Abstract

The invention relates to a synthesis resin curtain-wall-imitation interlayer coating. The synthesis resin curtain-wall-imitation interlayer coating is composed of a component A and a component B at aratio of 4-6:1 through mixing; the component A is composed of, by weight, 30.0 to 50.0% of hydroxy acrylic resin, 0.1 to 0.6% of an anti-settling agent, 5.0 to 15.0% of an organic solvent, 1.8 to 3.8%of an auxiliary agent, 5.0 to 35.0% of a pigment, and 23.0 to 43.0% of powdered steatile; the component B is composed of, by weight, 35.0 to 80.0% of a toluene diisocynate (TDI) and trimethylolpropane adduct or a tripolymer of TDI or a mixture of the adduct and the tripolymer, and 15.0 to 45.0% of butyl acetate. The advantages of the synthesis resin curtain-wall-imitation interlayer coating are that: the synthesis resin curtain-wall-imitation interlayer coating can be used for connection of a substrate layer with a finish, and improving the clunging force of finish with the building base layer (connecting effect between the preceding and the following).

Description

technical field [0001] The invention relates to an architectural paint, in particular to a synthetic resin imitation curtain wall intermediate layer paint. Background technique [0002] At present, building materials such as latex paint and solvent-based exterior wall paint are usually used for decoration on the surface of buildings, and are constructed according to the process of "one base and two sides". Easy to fade etc. Contents of the invention [0003] The purpose of the invention is to solve the existing problems of building materials such as latex paint and solvent-based exterior wall coatings in the prior art, and provide a kind of middle coating that can connect the base layer and the finish paint and improve the adhesion between the finish paint and the building base layer (connecting the preceding and the following) role). The present invention designs a kind of synthetic resin imitation curtain wall middle coating, it is characterized in that: be made of two...
