preparation example Construction

[0047] In some embodiments, the preparation method includes: adding the enhancer, synergist, and solvent into the reactor at a mass ratio of 1:0.025-2.5:20-50 and reacting at 20-100°C for 1- After 10 hours, after the reaction product is cooled, the solid matter is separated (for example, by vacuum filtration, etc.) and dried at room temperature for 10-30 hours, and then milled and sieved to finally obtain a reinforcing agent with active groups on the surface.

[0048] In some embodiments, the synergist includes a silane coupling agent and / or a polymer compound. Since the reinforcing agent has undergone surface modification treatment, it has -OH, -NH 3 and other active functional groups, which enhance the binding force between the coating and the fabric, thereby greatly improving the strength of the coating compared with the prior art.

[0049] Preferably, the silane coupling agent includes 3-aminopropyltrimethoxysilane, γ-(2,3-glycidoxy)propyltriethoxysilane, γ-methacryloxypr...

Abstract

The invention discloses a multifunctional high-strength composite fabric coating agent, a coating, and a preparation method and application of the multifunctional high-strength composite fabric coating agent. The multifunctional high-strength composite fabric coating agent comprises resin, a reinforcing agent of which the surface is provided with active groups, a difunctional dispersing agent, a levelling agent, a film forming agent, a softening agent, an antibacterial agent, a solvent and the like, wherein the reinforcing agent is subjected to surface modifying treatment and is provided with the active functional groups, such as -OH and -NH3. The fabric coating agent provided by the invention is convenient to apply, high in acting speed and stable in characteristics, and is basically suitable for the surfaces of fabrics made of any materials; moreover, the fabric which is treated by the fabric coating agent has very great tensile breaking force, excellent bursting performance and tearing performance, high waterproofing and moisture-penetration performance and antibacterial performance, and high adhesion force, can also be scraped and coated, rolled and coated, calendered or soaked repeatedly; and moreover, the preparation method of the coating agent is mature in process and low in production cost, and is suitable for large-scale popularization and application.

Description

technical field [0001] The invention specifically relates to a multifunctional high-strength composite fabric coating agent, a multifunctional high-strength composite fabric coating, a preparation method and application thereof, and belongs to the field of material technology. Background technique [0002] Fabric coating is a polymer compound that is uniformly coated on the surface of the fabric. It forms one or more layers of film on the surface of the fabric through adhesion, which can not only improve the appearance and style of the fabric, but also increase the function of the fabric, making the fabric have high strength, waterproof, water pressure resistance, breathable and moisture-permeable, flame-retardant and waterproof. Special functions such as pollution and shading reflection. [0003] Most of the fabrics currently on the market have low strength. The functional finishing of fabrics, that is, coating technology, can meet the main performance requirements of fab...
