Embodiment 1～5

[0055] This example provides a water-based silicate composite heat-insulating and flame-retardant coating, the formula of which is shown in Table 1 below. The water-based silicate composite heat-insulating and flame-retardant coating is prepared by the following method: put each component into a dispersing kettle and disperse for 15-20 minutes at a speed of 1000-1200 r / min, and finally form a colored paste, which is qualified after inspection and ready for use.

[0056] The formula (unit: g) of table 1 embodiment 1~5

[0057]

[0058] The auxiliary agent is composed of: defoamer (NXZ): 1g, preservative (LXE): 9g.

[0059] The composition of pigment and filler (370g) is: barium sulfate: 50g, kaolin: 150g, rutile titanium dioxide 100g, natural marble powder 50g, sericite powder 20g.

[0060] The composition of pigment and filler (600g) is: barium sulfate: 80g, kaolin: 240g, rutile titanium dioxide 160g, natural marble powder 80g, sericite powder 40g.

Abstract

The invention relates to a water-based silicate composite heat-insulating and flame-retardant coating and a preparation method thereof. The coating is composed of the following components in parts by mass: 30-40 parts of inorganic nano silicate resin; 0.7-5 parts of silicate water-based thixotropic agent; 5-7 parts of polycarbodiimide crosslinking agent; 5-10 parts of airgel powder; 0.5-2 parts of organically modified bentonite; 37-60 parts of pigments and fillers; 1-3 parts of film-forming aids; 10-20 parts of hollow ceramic beads; 0.5-1 part of agent; 15-20 parts of water. The coating is a water-based inorganic coating, which does not contain organic solvents and residual monomers, and has the advantages of no pollution and no waste; in addition, the coating has excellent adhesion, good alkali resistance, good weather resistance, heat insulation and flame retardancy , antibacterial function and hardness, multi-functional, convenient construction and low cost.

Description

technical field [0001] The invention belongs to the technical field of coatings, and more specifically relates to a water-based silicate composite heat-insulating and flame-retardant coating and a preparation method thereof. Background technique [0002] The modern world's economic leap and the high-speed development of world industrialization have led to a sharp deterioration of the earth's environment, and serious pollution threatens the living space of human beings. "Green" and "environmental protection" are new requirements for the coatings industry after people attach great importance to environmental protection, and they are also the development direction of coatings. [0003] In the prior art, due to the large amount of by-products, volatile solvents and residual monomers produced by architectural coatings, both environmental pollution and a waste of a large amount of resources and energy have been caused. Secondly, the coatings are applied to the surface of the wall....
