Problems solved by technology

At present, there are existing coatings with thermal insulation effect used on outdoor textiles. On the one hand, the thermal insulation effect is not ideal (heat insulation temperature difference is 10-15°C), and the link between the coating and the textile is not strong enough, resulting in a greatly reduced thermal insulation life. (After using for a period of time, the heat insulation temperature difference will be reduced to 0-5 ℃), on the other hand, the preparation method is complicated

Abstract

The invention relates to the technical field of coatings and particularly relates to a thermal insulation coating for outdoor textiles. The thermal insulation coating comprises 12-15% of titanium dioxide, 3-5% of coalescing agent, 37-45% of waterborne polyurethane resin, 17-25% of waterborne polyester resin, 3-5% of glass beads, 3-5% of auxiliary and water. The substances are added at different times and are prepared into a finished product under the control of different stirring rotation numbers. When coated on a textile, the thermal insulation coating not only has water resistance, ultraviolet resistance and other basic physical and chemical functions, but also is environment-friendly, free of generating organisms harmful to human bodies, particularly favorable in thermal insulation effect and long in thermal insulation life; after the thermal insulation coating is used in a rugged environment for a period of time, the inside and outside thermal insulation difference can be still kept at 23+ / -2 DEG C.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a heat-insulating coating and a preparation method thereof; it is mainly used in outdoor waterproof canvas, rubberized cloth, varnished cloth, flame-retardant cloth, plastic-coated cloth, textile awning, awning, tent or on textiles such as awnings made of synthetic materials. Background technique [0002] Coating is a general term for liquid or solid materials that can form a solid coating film with protection, decoration or special properties (such as insulation, anti-corrosion, signs, etc.) when applied to the surface of an object. [0003] With the improvement of people's living standards, the functional requirements of coatings are becoming more and more stringent. Among them, heat insulation coating is one of them. At present, there are two main types of coatings with heat insulation function in terms of characteristics and principles: [0004] 1. Isolated conduction type...
