Abstract

The invention relates to a production process of an environment-friendly badminton liquid crystal fiberboard. The environment-friendly badminton liquid crystal fiberboard is prepared from 12.5%-17.5% of polyether polyol, 10%-14% of polyester polyol, 12.5%-17.5% of a hydroxyl polyacrylonitrile copolymer, 6%-10% of hydroxyl polybutadiene, 2.5%-7.5% of IPDI, 5%-9% of MDI, 18%-22% of foaming agent water, 6%-10% of a foam stabilizer, 2.5%-7.5% of a catalyst A33 and 2.5%-7.5% of a catalyst T12. According to the production process of the environment-friendly badminton liquid crystal fiberboard, polyether polyol, polyester polyol, a hydroxyl polyacrylonitrile copolymer, hydroxyl polybutadiene, IPDI and MDI are used for synthesizing liquid crystal polymer resin, then foaming agent water, a foam stabilizer and catalysts A33 and T12 are mixed in a high-speed mechanical mixing manner then injected into a mold for foaming forming to prepare the liquid crystal fiberboard; and the liquid crystal fiberboard can replace a traditional PVC fiberboard, so that the rebound resilience of the shuttlecock is improved, the service life of the shuttlecock is prolonged, the user cost is reduced, and the pressure caused by waste shuttlecocks to the environment is reduced.

Description

technical field [0001] The invention relates to the technical field of badminton liquid crystal fiberboard production, in particular to an environment-friendly badminton liquid crystal fiberboard production process. Background technique [0002] The main structure of the existing badminton is the lower high-density cork, which has a density of about 180-190g / cm3, and the upper layer is PVC fiberboard (commonly known as table fiberboard in the industry) with a density of about 100g / cm3. Such a structure forms the effect of a tumbler, making the shuttlecock move in the air Its radian and directionality are well controllable, and it is widely used in badminton at all levels. [0003] However, there is a prominent defect of PVC fiberboard, which is poor elasticity, which makes badminton badly damaged in high-intensity confrontation, and has to be replaced frequently, resulting in higher exercise costs for users. . Contents of the invention [0004] Aiming at the deficiencies...
