Problems solved by technology

[0002] Traditional coatings are currently divided into two types: organic and inorganic. Organic coatings have low coating strength, poor heat resistance and weather resistance, while inorganic coatings have disadvantages such as poor decorative effects and weak elasticity.
After traditional coatings are applied to the wall, the service life is short, generally about 3-4 years. Due to the harsh external environment, the service life of exterior wall coatings is even shorter. The main reason is that the coating is gradually aging due to the erosion of external ultraviolet rays. , discoloration, depigmentation and peeling

Embodiment Construction

[0015] The present invention is described in detail below in conjunction with embodiment:

[0016] The main structure of nanometer interior and exterior wall modified coatings is divided into film-forming substances, dispersion media, pigments and fillers, and additives. The weight percentages of the raw material formulas are:

[0017] Acrylic emulsion 45%;

[0018] Disperse wetting agent 0.2%;

[0019] Titanium dioxide 6%;

[0020] Lithopone 6%;

[0021] Talc 4%;

[0022] nano-SiO 2 3%;

[0023] Nano-TiO 2 3%;

[0024] PH regulator 0.2%;

[0025] Water 27.6%;

[0026] The raw material water, additives, and filler pigments are prepared, stirred, and sanded, and additives are added again for deployment, and finally the materials are filtered and discharged. Among them, nano-SiO 2 、TiO 2 The particle size is about 45-55nm, preferably about 50nm. Since ultraviolet light is an electromagnetic wave shorter than the wavelength of visible light, its w...

Abstract

The main structure of said invented internal and external wall coating material respectively includes film-forming substance, dispersion medium, pigment filler and adjuvant, and its raw material formula is formed from (wt%) 35-55% of acrylic resin emulsion, 0.1-0.3% of dispersion moistening agent, 4-8% of titanium white powder, 4-8% of lithopone, 2-6% of talcum powder, 1.5-4.5% of nano SiO2, 1.5-4.5% of nano Tio2, 0.1-0.3% of pH regulating agent and 20-30% of water. The above-mentioned materials are stirred, ground and filtered so as to obtain the invented coating material with improved water-proofing property, contamination resistance, ageing resistance, UV ray resistance and bacteria-resisting property. Said coating material can be washed for above 11000 times, and its service life can be up to above 10 years.

Description

technical field [0001] The invention is a nanometer interior and exterior wall modified paint. Background technique [0002] Traditional coatings are currently divided into two types: organic and inorganic. Organic coatings have low coating strength, poor heat resistance and weather resistance, while inorganic coatings have disadvantages such as poor decorative effects and weak elasticity. After traditional coatings are applied to the wall, the service life is short, generally about 3-4 years. Due to the harsh external environment, the service life of exterior wall coatings is even shorter. The main reason is that the coating is gradually aging due to the erosion of external ultraviolet rays. , discolouration, discolouration and peeling. Contents of the invention [0003] In order to solve the above problems, the present invention provides a nanometer interior and exterior wall modified coating. It effectively improves the aging resistance of the coating, avoids the eros...
