Embodiment 1

[0015] A high-hardness EVA foam material for garden shoes, which is foamed from the following components: 30-40 parts of EVA material, 10-15 parts of EVA waste, 5-8 parts of high styrene, 10-15 parts of High pressure polyethylene, 4-6 parts of mineral oil, 10-15 parts of barium sulfate, 3-5 parts of crosslinking agent BIBP and 3-5 parts of foaming agent AC. As an example of the optimal formula: 30 parts of EVA material, 15 parts of EVA waste, 6 parts of high styrene, 12 parts of high pressure polyethylene, 5 parts of mineral oil, 12 parts of barium sulfate, 3 parts of Joint agent BIBP and 5 parts of blowing agent AC.

[0016] The concrete steps of the preparation technology of the high hardness EVA foam material of this optimum example are:

[0017] S1: Import the EVA waste into the crusher, after being crushed by the crusher, mix the EVA waste with mineral oil and half of barium sulfate, import it into the internal mixer for banburying, control the temperature at 150-180 deg...

Abstract

The invention discloses a high-hardness EVA foamed material for garden shoes, and a preparation process thereof, and belongs to the technical field of manufacturing of high-hardness EVA foamed materials for garden shoes. The EVA foamed material is prepared by foaming 30-40 parts of an EVA material, 10-15 parts of an EVA waste material, 5-8 parts of high styrene, 10-15 parts of high pressure polyethylene, 4-6 parts of mineral oil, 10-15 parts of inorganic filling particles, 3-5 parts of a cross-linking agent BIBP and 3-5 parts of a foaming agent AC. According to the invention, EVA, high-pressure polyethylene, SEBS and barium sulfate are added into the foaming material, and the EVA foaming material with Shore C hardness of 60 DEG or above is obtained through process adjustment, so that the special requirements of the market are met.

Description

technical field [0001] The invention relates to the technical field of making a high-hardness EVA foam material for garden shoes, in particular to a high-hardness EVA foam material for garden shoes and a preparation process thereof. Background technique [0002] Garden shoes, also known as hole shoes, are very similar in shape to slippers. The upper is covered with holes, and there is also a belt for anti-skid and rotation. It was named because it was mostly worn by gardeners at first. Because of its practical, stylish, light and comfortable features, it has been rapidly promoted in the market. And the hardness of existing garden shoes can generally only be achieved at 45-50 Shore hardness C, and cannot reach 60 degrees. To this end, we propose a high hardness EVA foam material for garden shoes and its preparation process. Contents of the invention [0003] The object of the present invention is to provide a high-hardness EVA foam material for garden shoes and its prepar...
