Abstract

The invention belongs to the technical field of polyurethane materials, and specifically relates to a composition for polyurethane boxing glove filler and a preparation method of the composition. The composition for the polyurethane boxing glove filler is prepared from a component A and a component B, wherein the component A is prepared from slow-rebound polyether polyol, polyurea polyol, high activity polyether polyol, a chain extender, a foam stabilizer, a foaming agent, a catalyst, an antioxidant, a light stabilizer and a solid filler; the component B is prepared from polyether polyol, isocyanate and a storage stabilizer. According to the composition for the polyurethane boxing glove filler, the all-water-blown formula design is performed, so that the ozone depletion potential ODP is zero, the prepared composition is nontoxic and protects the environment and is an environmentally-friendly material; the prepared polyurethane boxing glove products are outstanding in knock resisting and buffering performance and high in bearing rebound capacity, and therefore, the wrist and fingers can be prevented from being injured during boxing.

Description

technical field [0001] The invention belongs to the technical field of polyurethane materials, and in particular relates to a composition used as filler for polyurethane boxing gloves and a preparation method thereof. Background technique [0002] Boxing gloves are padded gloves used by athletes in boxing events. The purpose is to protect the boxer's wrist and finger joints. Boxers have powerful punches, and if they are not protected, they may easily dislocate their fingers. The most important thing about boxing gloves is the inner material, one is the filler of broken gauze, and the other is the filler of brown silk. Boxing gloves filled with shattered gauze are easy to deform during long-term use, and are likely to cause injury to boxers during boxing; boxing gloves filled with brown silk are heavy and bulky, and are not easy to carry. Contents of the invention [0003] The purpose of the present invention is to provide a composition for polyurethane boxing glove fill...
