Problems solved by technology

Chinese patent CN102850611A discloses a kind of EVA, styrene-butadiene rubber as the base material, adding glass fiber particles, using a twin-screw extruder to melt and graft to obtain a non-slip sole. Although it has a certain effect on improving the anti-skid performance of the sole, the low-temperature performance of the material It is not good, its anti-skid performance is greatly reduced under low temperature conditions, and the anti-skid effect under wet conditions is not described in this patent; The patent does not elaborate on the anti-skid performance on wet ice, nor does it study the effect of fiber orientation on the anti-skid performance

Abstract

The invention relates to long glass fiber reinforced TPU non-slip soles and a preparation method thereof. The long glass fiber reinforced TPU non-slip soles are characterized in that continuous long glass fibers are added into plastic polyurethane flexible plastic, and are directionally arranged, so that the strength of soles is greatly improved; and because the soles are made from the plastic in which thousands of glass fibers embedded and cellosilk is exposed to the surface of rubber, just like tiny nails to grip the ice surface, so that the friction between the soles and the slippery road surface is increased, meanwhile, a compatilizer adopted by the invention improves the cohesive force between the fibers and TPU of sole material, and the quality of the soles is improved; in addition, a certain amount of wear-resistant agent is added when the soles are prepared, so that the abrasion resistance of the soles is increased, and the service life is improved; according to the long glass fiber reinforced TPU non-slip soles and the preparation method thereof, provided by the invention, the preparation technology of the soles is a pultrusion process, and is convenient for the automated processing engineering control.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a long glass fiber reinforced TPU anti-skid shoe sole and a preparation method thereof. Background technique [0002] Anti-slip performance is one of the most basic performances of shoes, and good anti-slip performance of shoes is a necessary condition to ensure the safety of the wearer. Shoes for special occasions and special tasks, such as kitchen shoes, outdoor hiking shoes, and shoes for keeping warm in winter cold regions, etc., require outstanding anti-skid performance of the soles. For groups that perform special tasks such as troops, the anti-skid performance of shoes is also very important. Good anti-slip performance can not only ensure the completion of military tactical actions, but also avoid the danger of soldiers slipping and falling. If soldiers wear military shoes that are constantly slipping, it may cause deformation of tactical actions or deviation o...
