Problems solved by technology

Coated fabrics are coated on the selected fabrics by using coating equipment. It needs to be painted 2-3 times to achieve the required functional effect. Moreover, the coating slurry on the fabrics contains harmful solvents such as benzene series, so that it can be used The surface of the coating is smooth and smooth, and the coating slurry is composed of a variety of chemical raw materials, which seriously endangers the health of operators and users, and the curtain roller blinds made of coated fabrics are easy to age, fall off, not resistant to water washing, dry cleaning, and are not durable. It is beneficial for later cleaning and affects the appearance; the woven fabric is woven with a jacquard machine, using the bottom layer of the fabric, the surface layer, and a row of black shading silk in the middle to weave. The fabric has a high weight and a high cost of raw materials

Abstract

The invention provides a TPU (thermoplastic polyurethane) curtain lining layer and a preparation method thereof. The TPU curtain lining layer is prepared from 45 to 60 parts of dihydric alcohol, 35 to 50 parts of isocyanate, 0.05 to 0.25 part of dibutyltin dilaurate and 1.25 to 6.5 parts of inorganic filler. The dihydric alcohol is one or more of polytetrahydrofuran ether glycol, polycarbonate glycol and 1, 4-butanediol; the isocyanate is one or more of toluene diisocynate and 4, 4 '-diphenylmethane diisocyanate; the inorganic filler comprises carbonate, silicate and a carbon material; the carbonate comprises one or two of nano calcium carbonate and light calcium carbonate; the carbon material is one or more of carbon black, graphite, carbon nanotubes and graphene oxide. The polyurethane TPU curtain lining layer disclosed by the invention has the advantages of good shading effect, strong heat resistance, obvious sound insulation, water resistance, air permeability, aging resistance, excellent product overall quality and low processing cost, and is beneficial to environmental protection.

Description

Technical field [0001] The present invention relates to a curtain rollerine liner layer and a preparation method thereof, in particular to a polyurethane TPU curtain liner layer and a preparation method thereof. Background technique [0002] With the continuous improvement of technology development and living standards, people's environmental requirements in the living are also increasingly high, and curtains have become an indispensable supplies in family or office space. It plays an indoor lighting intensity, sunshade, and landscape indoor environment. Waiting for functions. [0003] Currently, the common light shielding layers of the curtain roller blinds on the market mainly include coating fabrics and shading fabrics. The coating fabric is a coating applying a coating apparatus on the selected fabric, and it is necessary to apply 2-3 times to achieve the desired functional effect, and the coated slurry on the fabric is a benzene product such as a hazardous solvent. The surfa...
