Problems solved by technology

[0004] ABS is the abbreviation of acrylonitrile / butadiene / styrene copolymer plastics. Due to the double bond structure in the butadiene part of the chemical composition, it is easily attacked by light and oxygen, which becomes the root cause of the poor weather resistance of ABS resin and affects its performance. service life
The traditional method is to add additives such as UV stabilizers and antioxidants, but it does not solve the problem from the root cause. After these additives are consumed, yellowing and brittleness will still occur, and the effect is not ideal.

Abstract

The invention relates to the technical field of plastic and in particular to a dynamic cross-linked type weather-resistant ABS (Acrylonitrile Butadiene Styrene) edge band material and a preparation method thereof. The dynamic cross-linked type weather-resistant ABS edge band material comprises the following raw materials in parts by weight: 100 parts of an ABS resin, 3-15 parts of a cross-linkingactivation agent, 0.5-5 parts of a cross-linking agent, 0.5-3 parts of an ultraviolet ray absorbent, 0.5-3 parts of an antioxidant and 0.2-2.5 parts of a lubricant, wherein the cross-linking agent isan organic sulfur compound. Due to addition of the organic sulfur compound cross-linking agent in ABS, cross-linking can be specifically carried out in double-bond positions in the ABS through the added cross-linking agent, and no reaction is implemented on other saturated carbon atoms, so that the content of double bonds in a polybutadiene rubber phase of the ABS is greatly reduced, a three-dimensional network structure is formed, molecule movement is limited, and the weather resistance of the ABS is improved.

Description

technical field [0001] The invention relates to the technical field of plastics, in particular to a dynamically cross-linked weather-resistant ABS edge banding material and a preparation method thereof. Background technique [0002] The edge banding commonly used in home decoration is generally divided into log edge banding and plastic edge banding. Although the log edge banding is simple to make, the cost is expensive, especially with the gradual improvement of people's awareness of forest resource protection, the raw material source of the log edge banding is limited, so that the plastic edge banding has been continuously developed. [0003] At present, the most commonly used edge banding materials are PVC plastic and ABS plastic. Among them, PVC is a brittle material, which often needs to add an appropriate proportion of low-molecular-weight plasticizers, and the formula is complex, there are many processing aids, and there are migration and Risk of extraction, potential...
