Embodiment 1

[0015] Embodiment 1: A special additive for adhesives, coatings and anti-mildew coatings, characterized by (percentage by weight): 48-52% of acrylic emulsion, 28-32% of titanium dioxide (TIO2), 14-16% of foam stabilizer , thickener 1.8-2.2%, anti-mildew additive 0.8-1.2%, ammonia 0.8-1.21%, color fixing agent 0.8-1.21%.

[0016] The anti-mold additive uses nano-silver antibacterial and anti-mold additives. Because the first is that nano-silver can easily enter pathogens because its structural unit size is between macroscopic substances and microscopic atoms and molecules, showing special surface effects, small size effects, quantum size effects and macroscopic quantum tunneling effects; Nano-silver particles are small in size, the volume percentage of the surface is large, the bonding state and electronic state of the surface are different from those inside the particle, and the incomplete coordination of surface atoms leads to an increase in the active sites on the surface, w...

Embodiment 2

[0020] Example 2: On the basis of Example 1, 50% of acrylic emulsion, 30% of titanium dioxide (TIO2), 15% of foam stabilizer, 2% of thickener, 1% of anti-mildew additive, 1% of ammonia water, fixing agent 1 %.

Embodiment 3

[0021] Example 3: On the basis of Example 1, in 100 parts of acrylic emulsion, add 28 parts of titanium dioxide (TIO2), 14 parts of foam stabilizer, 1.8 parts of thickener, 0.8 parts of anti-mold additives, 0.8 parts of ammonia water, 0.8 parts color fixing agent.

Abstract

The invention relates to a special additive of adhesive and paint mildew-resistant coating and a manufacturing method thereof. The special additive can effectively prevent mildew of paint and adhesive, can be produced in a natural environment, and will not give off harmful gas. The special additive is composed of the following components in percentage by weight: 48 to 52% of acrylic emulsion, 28 to 32% of titanium dioxide (TiO2), 14 to 16% of foam stabilizing agent, 1.8 to 2.2% of thickening agent, 0.8 to 1.2% of mildew resistant additive, 0.8 to 1.21% of ammoniacal liquor, and 0.8 to 1.21% of color fixing agent. The provided additive can effectively prevent products from mildewing in severe environment and prolongs the service life of products.

Description

technical field [0001] The invention relates to a special additive for adhesives and coatings, which can effectively prevent mildew of adhesives and coatings, and can be produced in a natural environment without volatilization of harmful gases, and a production method, which belongs to additives manufacturing field. Background technique [0002] CN104327568A, the name "a water-based paint for antibacterial, sterilizing and air-purifying glass doors", is characterized in that it is made of the following raw materials in parts by weight: water-based hydroxyl acrylic resin 30-34, water-based film-forming aids 7-9, organic Silicone polyester resin emulsion 13-15, water-based polyurethane resin 12-14, methyltrimethoxysilane 0.6-1.2, tributyl citrate 0.7-1.3, selenous nitrate 1-2, rare earth chloride 0.2-0.3, rosin Acid polyoxyethylene ester 0.3-0.5, dipropylene glycol monomethyl ether 2-3, polytetrafluoroethylene 1-2, m-phenylenediamine 2-3, pigment 1-2, N-methyldiethanolamine 1...
