Formula of coating solution and preparation method and application of coating solution

Abstract

The invention relates to a formula of a coating solution and a preparation method and application of the coating solution. The coating solution comprises the following raw material ingredients: graphene, polyurethane resin and water, wherein the mass ratio of the graphene to the polyurethane resin to the water is (0.18 to 0.23): 100: (50 to 80). A specific application method comprises the step of coating leather-based fabrics with the coating solution, wherein the leather-based fabrics comprise one or more of knitted fabrics, woven fabrics, non-woven fabrics, ultra-fiber non-woven fabrics and true skin. By adopting the technical scheme provided by the invention, the graphene is compounded into a coating material, so that prepared leather products, particularly leather summer-sleeping mats have excellent functions such as wear resistance, scratch resistance, electrostatic resistance, wave absorbing, bacterial resistance, mildew proofing, UV aging resistance, flame retarding, smoke suppressing, electromagnetic shielding and far-infrared health care; the grade of leather can be comprehensively improved, and the performance of cowhide summer sleeping mats in our country in the aspects of comfortability, durability and mildew proofing and bacterial resistance is improved.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a formulation of a coating liquid, a preparation method and application thereof. Background technique [0002] In recent years, with the development of the leather industry, leather products are more and more widely used in people's daily life, such as sofas, clothes until the popular summer mats and cushions in recent years. Among them, mats are indispensable as a good heatstroke prevention and cooling product suitable for all ages in summer and autumn high temperature seasons. At present, commercial summer mats are basically natural fiber summer mats, mainly straw mats, bamboo mats, linen mats, rattan mats and cowhide mats, etc., all made of natural fiber materials. Wherein, (1) Straw mat: cheap price, soft material, but poor cooling performance, not cool enough, and easily lead to human allergies, prone to acarids. (2) Bamboo mat: high thermal conductivity, cool, t...

AI Technical Summary

Problems solved by technology

(3) Linen mat: moisture-absorbing, breathable, antibacterial, but not cool enough, and too soft, poor flatness

Good toughness, not easy to break, soft and wear-resistant, good elasticity, foldable, long service life, comfortable, cool heat dissipation, sweat-absorbing and non-sticky, not moth-eaten, but the price is higher

(5) Cowhide mat: large heat capacity, good heat dissipation, excellent moisture-proof function, the disadvantage is that the skin feels sticky when sweating, and the price is high

Although the traditional leather mat made of natural leather has the advantages of smoothness, coolness, good water vapor permeability, many appearance changes and durability, it also has disadvantages such as not suitable for washing, easy to decolorize, and troublesome storage and maintenance.

The main hazards of non-compliance with rubbing color fastness: light ones are likely to cause pollution of light-colored clothing, and severe ones are likely to cause the components in the surface coating layer to be absorbed by the human body after contact, thereby affecting human health, and may also directly affect the quality of the product. service life
