Problems solved by technology

The brightness of the surface of the textile coating is relatively poor, so it is necessary to solve the problem of brightness by using bright adhesive resin, but most of the existing bright adhesive resins for textile coatings are resins synthesized by ordinary polyester polyols. When using it, the surface brightness is not bright enough and the transparency is not strong enough.

Abstract

The invention provides a castor oil modified high-gloss resin for a textile coating and a preparation method of the high-gloss resin. The high-gloss resin is prepared from the following components: polymeric diol, refined castor oil, ethylene glycol, isocyanate, AS (acrylonitrile-styrene) resin, dimethylformamide and the like. According to the invention, mixed polyols of different polyester polyols and refined castor oil are adopted to prepare the high-solid high-gloss surface glue resin for the medium-hard textile coating, wherein the solid content of the high-solid high-gloss surface glue resin is about 60%, the product viscosity is 60000-90000 CPS / 25 DEG C, and the 100% modulus is 60 + / -10. When the high-gloss resin is coated on the surface of a textile, the resin has good film-forming property and high gloss, so that a coating product is not too stiff and has good surface dryness, and the phenomenon that the product is abnormally adhered due to the high-gloss coating is avoided.

Description

technical field [0001] The embodiments disclosed in the present invention generally relate to the technical field of chemical engineering, and more specifically, relate to a castor oil-modified glossy resin for textile coatings and a preparation method thereof. Background technique [0002] Textile coating finishing agent, also known as coating glue, is a polymer compound that is evenly coated on the surface of the fabric. The original textile coating is mainly to solve the waterproof problem, but it has the defect of being impervious to moisture. The coated fabric has a stuffy feeling and poor comfort when used. In order to improve the air and moisture permeability of the coating adhesive, since the 1970s, researchers have developed a series of coating adhesives for waterproof and moisture-permeable fabrics by modifying the chemical structure of the coating adhesive and changing the coating processing method. . [0003] In recent years, functional coating adhesives and co...
