Embodiment 1

[0022] An adhesive for artificial leather, made of the following components in parts by weight: 72 parts of polyvinyl acetate, 11 parts of polydimethylsiloxane, 0.65 parts of potassium persulfate, γ-aminopropyl triethoxy 0.9 parts of silane, 2.8 parts of hydroxyethyl methylcellulose, 1.1 parts of sodium sulfate, 1.6 parts of magnesium chloride, 5.5 parts of water glass, 4.2 parts of triethanolamine, 38 parts of acetone, 1.6 parts of H-66 surfactant, 75 parts of deionized water 13 parts, attapulgite clay.

[0023] The attapulgite is modified, and the specific steps are as follows:

[0024] (1) Surface activation treatment:

[0025] Put the attapulgite into a hydrochloric acid solution with a mass fraction of 5 times its weight and be 15%, filter it out after soaking for 15 minutes;

[0026] (2) Surface modification treatment:

[0027] Treat the attapulgite treated in step (1) at a high temperature of 565°C for 30 minutes, then cool it down to room temperature naturally, soak...

Embodiment 2

[0036] An adhesive for artificial leather, made of the following components in parts by weight: 74 parts of polyvinyl acetate, 12 parts of polydimethylsiloxane, 0.7 parts of potassium persulfate, γ-aminopropyl triethoxy 1 part of silane, 3.1 parts of hydroxyethyl methylcellulose, 1.0 parts of sodium sulfate, 1.7 parts of magnesium chloride, 5.6 parts of water glass, 4.8 parts of triethanolamine, 40 parts of acetone, 1.3 parts of H-66 surfactant, 77 parts of deionized water part, 14 parts of attapulgite.

[0037] The modification method of attapulgite is the same as in Example 1, and the preparation method of the adhesive is the same as in Example 1.

Embodiment 3

[0039] An adhesive for artificial leather, made of the following components in parts by weight: 73 parts of polyvinyl acetate, 11 parts of polydimethylsiloxane, 0.75 parts of potassium persulfate, γ-aminopropyl triethoxy 1.1 parts of silane, 3 parts of hydroxyethyl methylcellulose, 1.2 parts of sodium sulfate, 1.5 parts of magnesium chloride, 5.4 parts of water glass, 4.7 parts of triethanolamine, 42 parts of acetone, 1.3 parts of H-66 surfactant, 77 parts of deionized water part, 12 parts of attapulgite.

Abstract

The invention relates to the technical field of chemical materials and discloses an artificial leather adhesive including polyvinyl acetate, polydimethylsiloxane, potassium persulfate, gamma-aminopropyltriethoxysilane, hydroxyethylmethylcellulose, sodium sulfate, magnesium chloride, sodium silicate, triethanolamine, acetone, H-66 surfactant, deionized water, and attapulgite. The artificial leatheradhesive is significantly improved in adhesion strength, greatly saves gluing materials, improves construction efficiency and reduces manpower cost.

Description

technical field [0001] The invention belongs to the technical field of chemical materials, and in particular relates to an adhesive for artificial leather and a preparation method thereof. Background technique [0002] Artificial leather is a plastic product that looks and feels like leather and can be used instead of it. It is usually made of fabric as the base, coated with synthetic resin and various plastics. [0003] At present, artificial leather adhesives are still in the development and trial stage in China. The product performance is not good, the wettability of the emulsion is average, the adhesion is greatly affected by the environment, the water resistance is average, and the comprehensive performance is low, which is far from satisfying people's requirements for the performance of artificial leather. requirements. Imported adhesives are expensive and unaffordable for most people. Contents of the invention [0004] The purpose of the present invention is to s...
