Calcium magnesium silicate/polyacrylic resin composite material as well as preparation method and application thereof

Abstract

The invention discloses a calcium magnesium silicate / polyacrylic resin composite material as well as a preparation method and application thereof. The calcium magnesium silicate / polyacrylic resin composite material comprises 3-30 parts of superfine calcium magnesium silicate powder, 100 parts of polyacrylic resin, 1-5 parts of sodium tripolyphosphate, 1-5 parts of sodium carboxymethyl cellulose and 1-5 parts of a silane coupling agent. The water absorption rate of the calcium magnesium silicate / polyacrylic resin composite material can be reduced from more than or equal to 100% to 40-70% compared with that of acrylic resin, meanwhile, the hand feeling of a coating is improved, and finished leather is endowed with smooth hand feeling.

Description

technical field

[0001] The invention relates to the technical field of tanning, in particular to a calcium magnesium silicate / polyacrylic acid resin composite material and a preparation method and application thereof. Background technique

[0002] Synthetic resins are commonly used in the retanning and finishing stages of the tanning industry. The synthetic resin used in the finishing section has higher requirements on the physical and mechanical properties and water and solvent erosion properties of the resin after film formation. Adding inorganic fillers and crosslinking agents to enhance the physical and mechanical properties of synthetic resins is a common method to improve the overall performance of synthetic resins. At present, inorganic fillers such as silica and talc are commonly used to reinforce synthetic resins. Usually, inorganic fillers are obtained from natural minerals through ball milling or laser cutting. However, the composition of natural minerals is com...
