By the colorful building coating of elastic water with reflective insulation effect that the technological process is produced, it is many that performance had both met water
The aeroelastic requirements of color building coating HG/T 4343-2012, reflective insulation performance meets the requirement of GB JG/T235-2014.This
3 kinds of excellent functions above that patent is provided are solved by the following method:
1) reflective insulation function.The reflective insulation effect of the product is to adopt reflection about by reflective insulation multi-color first
The infrared ray of more than 50&, followed by by reflective insulation floating coating reflection about 30% infrared ray, both and together can be by
To in air, performance meets JG/T235-2014 standards to 80% infrared reflection in sunshine, will with reach energy-conserving and environment-protective
Ask.
2) performance of aqueous colorful paint.By from the excellent protection rubber powder of protectiveness, from pliability and excellent weather resistance and hard
The different colorful emulsion of dispersed phase and continuous phase, and the cooperated technique for producing for passing through science, the aqueous colorful paint performance being made meet
HG/T 4343-2012 aeroelastic requirements;
3) anti-cracking function.The anti-cracking function of the patented product is mainly what is realized by following two aspects:During one is elasticity
Apply, performance meets JG/T and reaches GB outer wall building coating JG/T172-2014 II type requirements, and elongation percentage is more than 150%, has
Suitable cracking resistance;Two is the colorful mian paint of water, the emulsion selected by continuous phase and dispersed phase in addition to excellent weatherability,
Also there is certain elasticity, liquid has the ability for covering crackle.Both coordinate together, play the function of effectively covering crackle.
Preferred embodiment of the invention described in detail above.It should be appreciated that one of ordinary skill in the art without
Need creative work just can make many modifications and variations with design of the invention.Therefore, all technologies in the art
Personnel are available by logical analysis, reasoning, or a limited experiment on the basis of existing technology under this invention's idea
Technical scheme, all should be in the protection domain being defined in the patent claims.
