Description

The colorful stone-like coating of a kind of water burnt-in sand

Technical field

The present invention relates to a kind of stone-like coating, particularly the colorful stone-like coating of a kind of water burnt-in sand, belongs to building material field.

Background technology

Water-water multicolor finish is a kind of novel stone-like coating, this coating utilizes two or more the emulsion with different surfaces tension force in same system to co-exist in together but mutual exclusive principle, pass through spraying coating process, according to the needs of performance, the multi colour effect of various imitative stone type can be sprayed, beautiful in colour, be also called water-water multicolor spray paint.Along with continuous maturation and the popularization of technology, use very popular at present.Water-water multicolor finish is from past oil-in-water, and water-in-oil paint development, the color representation that it inherits oiliness multicolor finish has accomplished again environmental protection, healthy result.Compared with traditional stone-like coating, the advantage that water-water multicolor finish has the spraying of single rifle, once shaped, construction simply, are greatly saved the engineering time, reduced costs.Although water-water multicolor finish has many advantages, also come with some shortcomings part, and main manifestations has:

1, coating is too thin, and what " water-water " adopted is that basic emulsion coating is mixed colours as look grain, and coat-thickness only has about 0.3mm, often needs to carry out bottoming together with true mineral varnish spraying to strengthen texture.And because water-water coating is thinner, construction bottom is easily subject to external impacts, once be subject to external force to occur the phenomenons such as cracking, peeling possibly.

2, poor water resistance, the critical materials gelling material that water-water multicolor finish is formed is a kind of strong water-swelling type material, and containing a large amount of water miscible cellulose thickeners, so all can affect the water tolerance of the colorful exterior coating of water-water.

3, storage stability is poor, and the ripening degree of the whole system of water-water multicolor finish and stability need to improve, especially hot storage stability, easy layering, go bad, to cause spraying rear coating smudgy.

For the above problem of water-water multicolor finish, providing that a kind of thick coating, cohesive strength are high, water-tolerant, the colorful stone-like coating of water burnt-in sand that ageing-resistant, stability in storage is good, is a kind of technical progress in coating industry.

Summary of the invention

Technical problem to be solved by this invention, on the basis of water-water multicolor finish, by adding special linking agent and technique, utilize natural colour sand to make a kind of colorful stone-like coating of water burnt-in sand with wear-resisting, waterproof, anticorrosion, nontoxic, the cohesive force feature such as lucuriant in design by force, solve water-water multicolor finish poor water resistance, store instability, coating bag, deficiency that difficulty of construction is large.
