Abstract

The invention discloses an EPE material for a crawling pad, a preparation method of the EPE material and the crawling pad. The EPE material comprises the following components in parts by mass: 90-100 parts of low density polyethylene, 5-8 parts of a silane coupling agent, 0.5-2 parts of a butane foaming agent, 40-70 parts of talcum powder, 2-5 parts of glyceride, 1-3 parts of zinc oxide and 0.5-2 parts of stearic acid. The crawling pad prepared from the EPE material is favorable in water resistance, is flexible, light and elastic, can absorb and disperse external impact force through bending to achieve a buffer effect, overcomes the defects of deformation and poor rebound resilience, and meanwhile, has a thermal insulating effect and is easy to clean.

Description

technical field [0001] The invention relates to the field of crawling mats, in particular to an EPE material for a crawling mat, a preparation method thereof and a crawling mat. Background technique [0002] The crawling mat is an auxiliary product for babies to crawl. The materials are mainly EVA, XPE, and PVC. [0003] EVA material has a strong smell and low toxicity. EVA absorbs water and dust, and it will become very dirty after a few months of use, making it difficult to take care of. Moreover, EVA is silk screen printing, and the baby is in direct contact with the ink, and the ink is the most unstable substance, and long-term use will cause harm to the human body. The media has repeatedly reported that babies have skin allergies when using this product, so it is not recommended to use it; XPE is made of low-density polyethylene (LDPE) and ethylene-vinyl acetate copolymer (EVA) as the main raw materials, with fine and uniform cells , toughness, heat insulation, sound ...
