AI Technical Summary

Problems solved by technology

Coated blackout curtains mainly use multi-layer water-based coatings for direct knife coating, which feels stiff, or use solvent-based products with a plastic feeling, and the appearance effect is not ideal
The fabric coating technology of the prior art is all developed with waterproofing and fireproofing as the basic requirements. The publication number disclosed in the Chinese patent publication is CN103526544A, and the name is a coating of a velvet-free light-shielding coated cloth. Although it is fireproof and The waterproof performance is better, but due to the need for multi-layer coating, there are many ingredients, the process is more complicated, and the cost is higher, and the multi-layer structure is prone to seeping, sticking, insufficient shading, serious nest edge, and poor flatness And other problems, the yield rate is low

Abstract

A light-shielding coating for curtains, which comprises the following components in weight percentage: 40% to 44% of soft latex, 7% to 11% of hard latex, 19% to 21% of foam stabilizer, and 1.2% to 1.8% of crosslinking agent , fireproof glue 24%~28%, ammoniacal liquor 0.3%~0.7%, talcum powder 0.5%, thickener 0.5%; Described soft latex is the latex that viscosity is≤150mPa·s, and described hard latex is that viscosity is Latex <500mPa·s and >200mPa·s; 1), mixing and stirring; 2), foaming; 3), coating; 4), drying; 5), winding; compared with the prior art, this Under the premise of ensuring the original waterproof and fireproof performance, the invention has the characteristics of relatively few ingredients, simple process, good shading, high flatness, high yield and low cost.

Description

technical field [0001] The invention relates to a light-shielding coating for curtains and a using method thereof. Background technique [0002] At present, with the improvement of people's living standards, people have higher and higher requirements for the quality of curtains, and coating is one of the main factors affecting the quality of curtains. Research has found that in domestic or public fires, more than half of the deaths and one-third of the injuries are caused by the burning of decorative fabrics, home accessories and other textiles. Fabric flame retardancy is closely related to human life safety. [0003] Coating is a thin layer of plastic coated on metal, fabric, plastic and other substrates for the purpose of protection, insulation, decoration, etc. Coated blackout curtains mainly use multi-layer water-based coatings for direct knife coating, which feels stiff, or use solvent-based products with a plastic feeling, and the appearance effect is not ideal. The ...
