Abstract

The invention discloses a highly elastic plastic material and a preparation method thereof. The high elastic plastic material comprises the following raw materials in parts by weight: 20-30 parts of maleic anhydride-styrene copolymer, 10 parts of cobalt naphthenate -20 parts, 20-30 parts of 2-hydroxy-4-octyloxybenzophenone, 10-20 parts of lauric acid amide, 10-25 parts of trioctyl trimellitate, 7-13 parts of sodium perchlorate , 23-25 ​​parts of polydimethylsiloxane, 10-16 parts of silane coupling agent, 8-15 parts of epoxy soybean oil, and 10-20 parts of maleic anhydride. Granules, put into the mold to form. The resilience of the plastic material of the invention is close to 50%, the compression deformation is about 28%, and the heat shrinkage rate is 0.8-0.9%.

Description

technical field [0001] The invention relates to the field of plastics, in particular to a highly elastic plastic material and a preparation method thereof. Background technique [0002] At present, the structure of the sole is quite complicated. In a broad sense, it can include all materials that form the bottom such as the outsole, the midsole and the heel. In a narrow sense, it only refers to the outsole. The common characteristics of general sole materials should be wear-resistant, water-resistant, oil-resistant, heat-resistant, pressure-resistant, impact-resistant, good elasticity, easy to fit the shape of the foot, and not easy to change after being shaped. Heat preservation, easy to absorb moisture, etc., and at the same time, it must cooperate with the midsole, which has a braking effect when walking and changing feet, so that it will not slip and is easy to stop. There are many types of sole materials, which can be divided into natural base materials and synthetic b...
