Example Embodiment

[0015] Examples:

[0016] The lightweight rubber-plastic foaming material provided in this embodiment includes natural rubber, EVA plastic particles, foaming agent, cross-linking agent, sulfur and accelerator. The ingredients are 20 parts of natural rubber and EVA plastic according to the weight ratio. 80 parts of particles, which constitute 100 parts of rubber and plastic main material, the foaming agent added in the rubber and plastic main material is Ac foaming agent, and the amount of 100 parts by weight is added 3 parts of Ac to the rubber and plastic main material. Zinc oxide is selected as the crosslinking agent, and 2.5 parts of zinc oxide is added to 100 parts by weight of the rubber and plastic main material; the addition amount of sulfur and accelerator TMTD is 1 part per 100 parts by weight of the rubber and plastic main material Sulfur and 0.1 part of accelerator TMTD.

Example Embodiment

[0024] Example 2:

[0025] The lightweight rubber-plastic foam material described in this embodiment is formulated in a weight ratio of 30 parts of natural rubber and 70 parts of EVA plastic particles to form 100 parts of the main material of rubber and plastic. The foaming agent is Ac foaming agent, 4 parts of Ac foaming agent is added to the rubber and plastic main material with an amount of 100 parts by weight, zinc oxide is selected as the crosslinking agent, and 2.5 parts are added to the rubber and plastic main material with an amount of 100 parts by weight. Parts of zinc oxide; sulfur and accelerator TMTD are added in the amount of 1 part of sulfur and 0.1 part of accelerator TMTD per 100 parts by weight of the rubber and plastic main material. The lightweight rubber-plastic foam material made by this formula is used to make leather-like sheets. The lightweight rubber-plastic foamed material is tested with a Shore C hardness tester to achieve a hardness of 65 degrees.

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 ...
