Problems solved by technology

The results show that after embedding functionalized hydrogel particles on the surface of nylon 66 fiber fabric, the hydrogel layer will not affect the porosity and permeability of the modified nylon, and can significantly improve the wetting time of nylon fiber fabric, and its 24h water absorption The efficiency can be reduced by 41%; but the preparation process is complicated, the cycle is long, and the cost is high, which limits its scale production

Abstract

The invention relates to a nylon moisture retardant and a preparation method of the nylon moisture retardant. The nylon moisture retardant comprises the following components in percentage by weight: 20-50% of silicone powder, 20-60% of calcium oxide, 5-35% of titanium dioxide and 1-30% of a synergist. The preparation method comprises the following steps: adding the raw materials to a high-speed mixer; carrying out constant-temperature stirring for 15-20 minutes; and discharging the raw materials, so as to obtain a plastic additive. By adopting the nylon moisture retardant disclosed by the invention, good physical and mechanical properties of a nylon product can be kept, meanwhile, the hygroscopicity of the nylon product can be obviously improved, the nylon product can be used at high humidity, the dimensional stability of the materials is kept, and the production cost of the nylon product can be effectively reduced.

Description

technical field [0001] The invention relates to the field of plastic additives, in particular to a nylon anti-humidity agent capable of maintaining the excellent physical and mechanical properties of nylon plastic products and significantly improving the hygroscopicity of nylon plastic products and a preparation method thereof. technical background [0002] Nylon is one of the varieties with the earliest development and large output in engineering plastics. Compared with other engineering plastics, nylon has high mechanical strength, wear resistance, good self-lubrication, oil resistance, corrosion resistance, good processing fluidity, and excellent comprehensive performance. Its output ranks first among the five major engineering plastics, and it has been widely used Used in machinery, chemical industry, instrumentation, automobile and other fields. Because the amide group (-NHCO-) ​​in the nylon molecule is a hydrophilic group, the nylon has a strong hydrophilicity, and t...
