Embodiment 1

[0031] According to the synthetic leather of this embodiment, the foaming resin for rubbing scorched yambuck with upside-down wool is composed of the following raw materials in weight ratio: 45 parts of solvent-based PU resin, fine high-temperature yambuck powder (model F -50D) 1.6 parts, coarse low-temperature yangbuck powder (model F-48D) 0.9 parts, butanone 40 parts, toluene 10 parts and silicone oil 2.5 parts.

[0032] The preparation method of the foamed resin is as follows: according to the above components and proportions, add fine high-temperature yambuck powder, coarse low-temperature yambuck powder, methyl ethyl ketone, toluene and organic silicone oil to the PU resin, stir at high speed until the dispersion is uniform, Filter, that is. The performance index of the foamed resin obtained is: appearance: milky white viscous liquid; viscosity 1500-2500CPS / 25°C; solid content 20±1%.

Abstract

The invention relates to nap-up and nap-down brushed yarn buck foaming resin for synthetic leather and a preparation method thereof. The yarn buck foaming resin consists of the following raw materials in parts by weight: 40-50 parts of solvent type PU (Poly Urethane) resin, 1-2 parts of refined high-temperature yarn buck powder, 0.5-2 parts of coarse low-temperature yarn buck powder, 30-50 parts of butanone, 5-15 parts of methylbenzene and 1-3 parts of organic silicone oil. The preparation method of the foaming resin comprises the following steps of: adding the refined high-temperature yarn buck powder, the coarse low-temperature yarn buck powder, the butanone, the methylbenzene and the organic silicone oil into the solvent type PU resin according to formula amounts; stirring at a high speed till the raw materials are dispersed uniformly; and filtering to obtain the nap-up and nap-down brushed yarn buck foaming resin. The foaming resin has the advantages of remarkable nap-up and nap-down effects, smooth handfeel, good touch feel, easiness for brushing, oil coke feel and the like, and can be used for preparing leather in the classic style, and the like.

Description

technical field [0001] The invention belongs to the technical field of preparation of yambuck foaming resin for synthetic leather, in particular to a yambuck foaming resin and a preparation method thereof. Background technique [0002] At present, the surface treatment methods of leather products including luggage, clothing, shoes, etc. are various, and the effect styles are varied: high-gloss high-solid, oily leather style, polished style, crazy horse discoloration, yangbuck, etc., whether it is in surface effects or in In terms of feel, it is still pursuing the imitation leather effect. [0003] Yangbuck foaming resin occupies a large proportion in the leather market in recent years. It uses Yangbuck powder to expand and foam, forming a fluffy effect on the surface of synthetic leather. The post-production process can make different styles of leather products similar to real fur. Yangbuck powder is a special microsphere foaming agent for leather provided by Japan Matsumo...
