This invention relates to the field of sports field materials, and particularly to a high-performance sports field surface material based on aerogel and its preparation method. The high-performance sports field surface material based on aerogel comprises polyurethane emulsion, aerogel, auxiliary elastic agents, stabilizing and reinforcing agents, wetting and dispersing agents, and crosslinking agents. The high-performance sports field surface material based on aerogel prepared according to this invention is a novel sports field surface material that simultaneously achieves excellent cushioning performance, temperature resistance, and long-term durability. It balances the performance contradictions of existing long-term materials, solves their inherent difficulties, and significantly enhances the overall application performance of field materials.

The invention discloses a bio-based all-cotton fluoride-free waterproof fabric for a high-performance sports cap and a preparation method of the bio-based all-cotton fluoride-free waterproof fabric, and relates to the field of biochemical treatment and preparation of textile fabrics. The garment body is made of fabric, the fabric comprises a bio-based all-cotton base material, a compound enzyme treatment layer, a bio-based modified layer and a fluoride-free waterproof layer, compound enzyme is composed of cellulase, pectinase and lipase, the raw material of the bio-based modified layer is bio-based polyol, and the raw material of the fluoride-free waterproof layer is a polycaprolactone fluoride-free waterproof agent. The preparation method comprises the following steps: firstly cleaning and drying the base material, then carrying out compound enzyme biochemical treatment and bio-based polyol grafting reaction, and finally padding and curing through a fluoride-free waterproof agent. The fabric and the method meet the fluoride-free and environment-friendly requirements and meet the use requirements of high-performance sports caps, and the comprehensive performance of the fabric is improved by means of a biochemical treatment process.

The invention provides epoxy resin for a carbon fiber bicycle prepreg. The epoxy resin comprises resin, silicon powder, a curing agent, a flame retardant, a flexibilizer, imidazole and a coupling agent. According to the invention, glycidyl amine type epoxy resin meeting the quality standard is selected as basic resin, silicon powder is used as a filling material, modified anhydride is used as a curing agent, layered dihydroxy compounds (LDHs) are used as a flame retardant, and a proper flexibilizer and an imidazole compound catalyst are used as curing accelerators; and the silane coupling agent is used as a material for enhancing the binding force between the inorganic filler and the resin matrix. According to the carbon fiber bicycle component prepreg and the preparation method thereof, the single mechanical property is remarkably improved, more importantly, the comprehensive performance is comprehensively improved, the carbon fiber bicycle component prepreg can better adapt to various complex working conditions in practical application, and the strict requirements of high-end fields such as high-performance sports equipment and aerospace are met.
