Production process of T buckle

Abstract

The invention discloses a production process of a T buckle. The T buckle is prepared from the following raw materials in parts by weight: 80 to 90 parts of polyformaldehyde, 10 to 20 parts of polyurethane, 0.3 to 0.7 part of an antioxidant 1010, 0.1 to 0.5 part of a phosphorous acid aid and 0.2 to 0.6 part of an anti-ultraviolet agent. According to the production process of the T buckle, the arranged antioxidant 1010 can react with free radicals generated by a polymer to interrupt the chain reaction of molecular chains, so that free formaldehyde is deactivated; hydroperoxide can be decomposedinto inactive products through the arranged phosphorous acid aid so as to inhibit the automatic catalytic action of the hydroperoxide, and the antioxidant 1010 and the phosphorous acid aid can generate a strong synergistic effect; the antioxidant is used together with an ultraviolet light absorber, so that active products formed by the antioxidant under illumination can be eliminated, the sulfideis prevented from being decomposed, and the antioxidant is a light-resistant and heat-resistant antioxidant stable system; and along with the time and the temperature rise, the thermal oxidative degradation of the plastic can be reduced, and the stability of the plastic during molding processing is improved.

Description

technical field [0001] The invention relates to the technical field of injection molding, in particular to a production process of a T buckle. Background technique [0002] A buckle is a mechanism used for the embedded connection or integral locking of one part and another part, usually used for the connection of plastic parts, and its material is usually made of plastic material with certain flexibility. The biggest feature of the snap connection is that it is easy to install and disassemble, and can be disassembled without tools. Now the buckle connection technology has been widely used in the connection of automotive interior parts. [0003] T buckle, as an important kind of buckle, is becoming more and more important as the buckle is widely used. The existing T buckle is generally made of plastic, and the molecular chain is formed by heat and light during molding and use. It is easy to break and generate free radicals, coupled with the oxidation in the environment, it ...

[0003] T buckle, as an important kind of buckle, is becoming more and more important as the buckle is widely used. The existing T buckle is generally made of plastic, and the molecular chain is formed by heat and light during molding and use. It is easy to break and generate free radicals, coupled with the oxidation in the environment, it will accelerate the breakage of molecular chains, and eventually become a polymer with a very low molecular weight, which loses the value of use, and because the T buckle is a plastic injection molding product, the T buckle The production process is of great significance to the production of T buckle, so that its production has samples and has great reference value
