Embodiment

[0026] An outdoor cloth using the environment-friendly anti-ultraviolet finishing agent. The coating of the outdoor cloth is processed through two processes. During the coating process, the environment-friendly anti-ultraviolet finishing agent is added to the polyacrylate glue .

[0027] In the first process, the formula of polyacrylate glue is calculated in parts by weight: 43 parts of 2200 neutral glue, 43 parts of 2820 soft glue, 3 parts of environmental protection anti-ultraviolet finishing agent, 1 part of slip agent, bridging agent 2 parts and 8 parts of solvent, the viscosity is 16000~18000CPS, the amount of glue used is 30-33g / ㎡, the oven temperature is 160℃, and the vehicle speed is 70m / min. The particle size of titanium dioxide in 3 parts of environmental protection anti-ultraviolet finishing agent is controlled at 0.1 μm.

[0028] In the second process, the formula of polyacrylate glue is calculated by weight: 78.6 parts of 2200 neutral glue, 6.2 parts of environme...

Abstract

The invention relates to an environment-friendly anti-ultraviolet finishing agent with excellent anti-ultraviolet effect, environmental protection and cost saving and outdoor cloth using the finishingagent. The environment-friendly anti-ultraviolet finishing agent comprises titanium dioxide, a coloring agent, diacetone alcohol, ethyl acetate, butyl ester and a dispersing agent. The product prepared by the invention is folded with the conventional product for thirty times, and the adhesive film fastness of the outdoor cloth prepared by the invention is obviously better; by detecting the ultraviolet resistance, the prepared outdoor cloth can reach UPF50+ or more, and the UVA passing rate is less than 5%; after the conventional product is dried at a high temperature of 210 DEG C for 15 seconds, the ultraviolet resistance of the conventional product is sharply reduced, and the outdoor cloth prepared by the invention has no obvious change. A coating process is adjusted, no potential safetyhazards exist, the environment-friendly anti-ultraviolet finishing agent is environment-friendly, does not pollute recycling activated carbon, and does not influence normal use of a toluene recyclingmachine either, the cost is saved, and the quality is excellent.

Description

technical field [0001] The invention relates to the field of fabric finishing agents, in particular to an environment-friendly and cost-saving anti-ultraviolet finishing agent with excellent anti-ultraviolet effect and an outdoor cloth using the same. Background technique [0002] Ultraviolet rays (ultraviolet rays referred to as UV) are divided into long-wave ultraviolet (UV-A, 320-400nm), medium-wave ultraviolet (UV-B, 280-320nm) and short-wave ultraviolet (UV-C, 200-280nm). The effect of UV-B is 1000 times that of UV-A. The mildew in summer is mainly due to the effect of UV-B. After the subcutaneous blood vessels absorb ultraviolet B, they will expand and make the skin red and produce erythema. In severe cases, inflammation will occur. It can also affect the elastic fibers under the skin, causing the skin to lose its elasticity and form rough wrinkles. As a stronger ultraviolet light, UB-C has a certain bactericidal effect, but it is also harmful to the human body. Gener...
