Embodiment Construction

[0014] 1. Preparation:

[0015] rutile nano-TiO 2 Process it until the average particle size is 80nm, and then use it.

[0016] Weigh 12kg of styrene-acrylic emulsion, 2.6kg~3.0kg of nano-TiO 2 , 2.2 kg SiO 2 , 0.5 kg inorganic antibacterial and antifungal agent, 1.2 kg negative ion generating powder, 0.2 kg cellulose, 2.9 kg AS881 superfine aluminum silicate, 40 kg filler, 0.8kg film-forming aid, 0.6kg dispersant, 0.4kg thickener , 0.5kg stain resistance agent and 0.7kg viscosity stabilizer.

[0017] The raw material inorganic antibacterial antifungal agent contains Ag + and Cu 2+ , Ag + Accounting for 2.8% of the mass of inorganic antibacterial and antifungal agents, Cu 2+ It accounts for 1.7% of the mass of inorganic antibacterial and antifungal agents.

[0018] 2. Processing technology:

[0019] First, the styrene-acrylic emulsion, additives (composed of film-forming additives, dispersants, thickeners, stain-resistant agents and viscosity stabilizers), nano-TiO 2...

Abstract

The invention discloses a production technology of a super stain-resistant waterborne compound coating, and relates to the technical field of production of a coating for a building wall. The production technology comprises the following steps: firstly, mixing and grinding styrene-acrylic emulsion, an assistant, nano TiO2, SiO2, negative ion powder, cellulose and water; adding a part of AS881 ultra-fine aluminum silicate; adding an inorganic antibacterial and anti-enzyme agent after grinding; adding a filler and another part of AS881 ultra-fine aluminum silicate after mixing; and evenly mixing to form the waterborne compound coating. By adopting the production technology, the problems of unsound coating structure and poor hydrophobicity of the coating structure are avoided; the puzzle of poor stain resistance of the coating is solved; the production technology also has the characteristics of being good in resistance to washing, small in hygroscopicity and good in stain resistance; the coating cost is reduced; the super stain-resistant waterborne compound coating is the coating for inner and outer walls of a building, which is good in super stain resistance, crazing resistance and hydrophobicity, good in ceramic imitating property, and high in hiding rate.

Description

technical field [0001] The invention relates to the technical field of production of coatings for building walls. Background technique [0002] Most of the exterior walls of buildings are decorated with coatings. The current coating film structure is not dense, the water repellency is poor, and the antifouling property is poor. To have a certain impact. Contents of the invention [0003] The object of the invention is to propose a production process of a super-stain-resistant and water-resistant composite coating that is not easily polluted. [0004] In the present invention, styrene-acrylic emulsion, additives, nano-TiO 2 , SiO 2 , Negative ion generating powder, cellulose and water are mixed and ground, then add part of AS881 superfine aluminum silicate, after grinding, add inorganic antibacterial and antifungal agent, after mixing, add filler and another part of AS881 superfine aluminum silicate, mix well , Serve. [0005] Nano-TiO with shielding, absorption and sc...
