Abstract

The invention discloses a light rubber plastic foam material and a production method and application thereof. The material is characterized in that: the material comprises the following components in part by weight: 20 to 30 parts of natural rubber, 80 to 70 parts of EVA plastic granules, 3 to 4 parts of Ac foaming agent added based on 100 parts of rubber plastic main material, 2.5 parts of zinc oxide serving as a cross-linking agent added based on 100 parts of rubber plastic main material, and 1 part of sulphur and 0.1 part of accelerating agent TMTD added based on 100 parts of rubber plastic main material. The light rubber plastic foam material obtained by the production method has light and attractive appearance quality, realizes comfortable feeling when used for making soles and has an even and dense internal structure. The light rubber plastic foam material has the characteristics of high tensile strength, high tearing strength, good rebound resilience and low compression set.

Description

technical field [0001] The invention relates to a production technology of chemical materials, in particular to a lightweight rubber and plastic foam material and its production method and application. Background technique [0002] Application No. 200910020027.6 is a medical rubber-plastic composite material, which is composed of polyvinyl chloride (PVC) resin powder, composite rubber-plastic particles, phthalates, stabilizers and lubricants, etc. This rubber-plastic composite material Its chemical properties are stable, flexible, elastic, and tough, but it is not suitable for foaming shoe soles or imitation leather products. Other existing rubber and plastic foam materials can only be used for packaging and cladding due to lack of tensile strength, tear strength, resilience, etc.; as the application number is 200610096913. Rubber and plastic foam, it is just that the rubber and plastic foam has elastic rubber and plastic foam strips that tend to curl and is spirally wound ...
