Abstract

The invention provides a polyurethane rubber texture coating which is characterized by comprising the following components by mass percent: 25.0%-30.0% of an emulsion, 60%-65% of EPDM color particles, 0%-0.5% of a neutralizing agent, 0.1%-0.2% of an organic silicon defoaming agent, 0%-0.5% of a preservative, 0.1%-3.0% of a thickening agent, 1.0%-5.0% of a film-forming aid, 1.0%-4.0% of an antifreezing agent and 0.5%-10% of water. According to the texture coating, the defects that an external wall real stone paint coating is not environmental friendly, not uniform in color, inconvenient to transport, easy to crack when in construction and the like can be effectively overcome. The texture coating has the characteristics of no fading within continuous 3-5 years, no crack, stability, no toxicity, no smell and greenness. The invention further provides a preparation method of the texture coating. The preparation method is simple in process, green and suitable for large-scale industrialized production, and no toxic materials are generated during production.

Description

technical field [0001] The invention relates to the field of coatings, in particular to polyurethane coatings, in particular to a polyurethane rubber texture coating and a preparation method thereof. Background technique [0002] Traditional real stone paint is mainly made of high molecular polymer, natural colored stone sand and related additives. After drying and curing, it is as hard as stone and looks like natural real stone. Some real stone paint coatings will turn white every time it rains, and the coating will become loose, and after the rain stops, the coating will return to its original color after the sun stops. The reason is that the water resistance of the coating is not good. Absorbed water, it may also be that the high molecular polymer, that is, the emulsion, is not completely dry, and the film is not formed in time, causing the emulsion to turn white when it meets water. But the biggest reason is that the traditional real stone paint does not have any filler...
