Embodiment 1

[0028] Embodiment 1: This embodiment proposes a leather crystal coating, including the following raw materials in parts by weight: 10 parts of modified polyurethane resin, 3 parts of nitrocellulose, 3 parts of amyl acetate, 4 parts of ethanol, casein 5 parts, 3 parts of polyhydric compound, 1 part of polyisocyanate, 0.1 part of silane coupling agent and 0.5 part of ammonia water.

[0029] The modified polyurethane resin adopts silicone modified polyurethane resin.

[0030] Nitrocellulose uses digested cellulose with a nitrogen content of 12%, because nitrocellulose with a nitrogen content lower than 10.5% has poor solubility, while nitrocellulose with a nitrogen content higher than 12.2% is easy to decompose and explode, and has poor light resistance and heat resistance , easy to age, not suitable for the preparation of nitro lacquer, so choose nitrocellulose with nitrogen content between 10.5% and 12.2%.

Embodiment 2

[0040] Embodiment two: the present embodiment proposes a leather crystal coating, comprising the following raw materials in parts by weight: 12 parts of modified polyurethane resin, 2 parts of nitrocellulose, 2 parts of amyl acetate, 3 parts of ethanol, casein 4 parts, 2 parts of polyvalent compound, 1 part of polyisocyanate, 0.1 part of silane coupling agent and 0.5 part of ammonia water.

[0041] The modified polyurethane resin adopts silicone modified polyurethane resin.

[0042] Nitrocellulose uses digested cellulose with a nitrogen content of 12%, because nitrocellulose with a nitrogen content lower than 10.5% has poor solubility, while nitrocellulose with a nitrogen content higher than 12.2% is easy to decompose and explode, and has poor light resistance and heat resistance , easy to age, not suitable for the preparation of nitro lacquer, so choose nitrocellulose with nitrogen content between 10.5% and 12.2%.

Embodiment 3

[0052] Embodiment Three: The present embodiment proposes a leather crystal coating, comprising the following raw materials in parts by weight: 15 parts of modified polyurethane resin, 3 parts of nitrocellulose, 4 parts of amyl acetate, 4 parts of ethanol, casein 3 parts, 2.5 parts of polyhydric compound, 2 parts of polyisocyanate, 0.1 part of silane coupling agent and 0.5 part of ammonia water.

[0053] The modified polyurethane resin adopts silicone modified polyurethane resin.

[0054] Nitrocellulose uses digested cellulose with a nitrogen content of 12%, because nitrocellulose with a nitrogen content lower than 10.5% has poor solubility, while nitrocellulose with a nitrogen content higher than 12.2% is easy to decompose and explode, and has poor light resistance and heat resistance , easy to age, not suitable for the preparation of nitro lacquer, so choose nitrocellulose with nitrogen content between 10.5% and 12.2%.

Abstract

The invention relates to the technical field of coatings, and discloses a leather crystal plating coating. Casein for leather finish has the advantages that (1) the leather is high in bonding force, and is unlikely to fall off due to friction; (2) a film formed by the casein is good in temperature resistance, machine polishing-resistant and ironing-resistant; (3) the casein finish is good in sanitary performance and has good ventilating property and gas permeability; and (4) the casein finish can keep natural grain of the leather and is flexible in glossiness. By taking low price methylbenzeneand benzene as raw materials for toluene diisocynate in polyisocyanate, the economical cost is low, and the manufacturing cost of the leather coating can be saved. Two isocyanate groups are same in activity and small in irritation. An adhesive prepared from the raw materials has relatively high bonding strength and impact toughness. The bonding performance of resin can be improved by means of a saline coupling agent, so that performance such as strength, electricity, waterproofness, climate resistance of a glass fiber enhanced composite material are improved greatly.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to leather crystal coatings. Background technique [0002] Leather finishing is a kind of coating, which makes the leather surface of leather products form various colors, luster and style appearances, and makes the leather obtain a certain degree of water resistance and easy maintenance. [0003] Leather finishing can increase the characteristics of leather such as corrosion resistance and wear resistance, and can greatly increase the service life of leather products. Ability to item performance strength. Therefore need badly a kind of leather crystal plating coating to solve the above problems. Contents of the invention [0004] (1) Solved technical problems [0005] Aiming at the deficiencies of the prior art, the present invention provides leather crystal-plated coatings, which have the advantages of focusing on the ability of leather coatings to increase the performance a...
