Problems solved by technology

However, there are the following problems in the production process of PVC foam shoes: 1. Dust problem; 2. The feeding steps are cumbersome and the process is complicated; 3. The bubble structure is irregular
The processing cycle is long and the operation is cumbersome, resulting in low production efficiency
Moreover, the decomposition temperature of AC and ADC is relatively high, and they are exothermic foaming agents. During the decomposition process, the heat is released continuously, which makes the temperature rise rapidly, and the decomposition temperature range is short, resulting in the sudden decomposition of the foaming agent and the pore structure. Irregular

Abstract

The invention provides a master batch material, a preparation method and application of a foaming master batch, and a preparation method of a foaming shoe, and belongs to the technical field of high polymer material processing, and the master batch material is specifically prepared from the following components in parts by weight: 5-10 parts of carrier resin, 5-15 parts of a plasticizer, 20-26 parts of a foaming aid, 20-38 parts of a stabilizer and 20-31 parts of a foaming agent, wherein the foaming agent is a mixture of thermal expansion microspheres and an azodicarbonamide foaming agent. Through the treatment scheme disclosed by the invention, foam holes formed after the master batch material is foamed are more uniform and stable, the obtained product is uniform and stable in foaming, and the prepared foamed product is better in mechanical property.

Description

technical field [0001] The invention relates to the technical field of polymer material processing, in particular to a master batch material, a preparation method and application of a foamed master batch, and a preparation method for foamed shoes. Background technique [0002] Polyvinyl chloride (PVC) is one of the five largest synthetic resins in the world. PVC material has the characteristics of high strength, low price, good chemical corrosion resistance, good electrical insulation and difficult to burn. It is widely used in the footwear industry, Engineering construction, food packaging and electrical. However, there are the following problems in the production process of PVC foam shoes: 1. Dust problem; 2. The feeding steps are cumbersome and the technological operation process is complicated; 3. The bubble structure is irregular. [0003] When preparing PVC foam shoes, a certain amount of foaming agent needs to be added. At present, the foaming agent added mainly adop...
