Embodiment 1

[0042] Embodiment one: the calcium silicate hydrate nano coating of the present invention contains the following components calculated by mass percentage:

[0043] Acrylic film-forming emulsion: any value between 37.0 and 39.0%;

[0044] Pigment: any value between 5.07% and 6.20%;

[0045] Talc powder: any value between 6.50% and 7.50%;

[0046] Calcium silicate hydrate powder: any value between 10.5% and 11.0%;

[0047] Coalescing aids: Any value between 0.38% and 0.88%;

[0048] Defoamer: any value between 0.4% and 0.9%;

[0049] Water: any value between 34.52% and 40.5%.

[0050] The above-mentioned acrylic film-forming emulsion can be pure acrylic emulsion, styrene-acrylic emulsion or silicone-acrylic emulsion. This ratio uses pure acrylic emulsion, for example: XG-2002 construction emulsion adhesive.

[0051] In addition to the above components, the paint can also contain 0-3% dispersant, and the dispersant can be selected from sodium hexametaphosphate or sodium pol...

Abstract

The nanometer hydrated calcium silicate paint consists of filming emulsion 37.0-39.0 wt%, pigment 5.07-6.20 wt%, talcum powder 6.50-7.50 wt%, hydrated calcium silicate powder 10.15-11.0 wt%, filming assistant 0.38-0.88 wt%, defoaming agent 0.4-0.9 wt% and water 34.52-40.50 wt%. The hydrated calcium silicate powder is prepared with cheap diatomite as siliceous material and lime as calcium material, and through dynamic hydrothermal process, and has low crystallization degree and very great specific surface area. Using the nanometer hydrated calcium silicate as stuffing for building paint can raise the adhesion force, water resistance, alkali resistance, water resistance, ageing resistance and antifouling performance of paint greatly and is favorable environment protection.

Description

(1) Technical field [0001] The invention relates to an architectural coating and a production method thereof. (two), background technology [0002] Existing architectural coatings generally contain film-forming emulsions (base materials), pigments, fillers, film-forming aids, defoamers, and water, among which the fillers are mostly inert substances such as talcum powder. Existing fillers such as talcum powder mainly play a covering role, and the performance of the coating mainly depends on the performance of the base material. At present, the research on high-performance coatings at home and abroad mainly focuses on the use of base materials with excellent properties, but often because of their high prices, they cannot be mass-produced and applied. Due to the limitations of the existing base materials, the adhesion, scrub resistance, alkali resistance, water resistance, aging resistance and pollution resistance of the existing architectural coatings are not satisfactory and...
