Problems solved by technology

[0003] The sub-chain of TPU is generally composed of hard segment and soft segment. The soft segment is generally hydroxyl-terminated polyether, polyester and polyolefin, etc. The hard segment is generally formed of polyurethane by chain extender and isocyanate. Various industries such as medical treatment and chemistry, but the existing TPU material film cannot guarantee its waterproof performance in the material ratio. In high-demand industries, the stability of the product is poor. It increases the production cost, and it is inconvenient to control during the production process, which is not conducive to the operation of workers and affects the stability of production and processing

Abstract

The invention discloses a waterproof TPU film technology and a formula. The waterproof TPU film technology and the formula are characterized in that the formula is prepared from 70 to 80 percent of TUF particles, 5 to 8 percent of ABS-g-maleic anhydride, 1 to 3 percent of silica, 6 to 10 percent of natural polyphenol, 10 to 15 percent of epoxy resin and 3 to 5 percent of a light stabilizer. According to the waterproof TPU film technology and the formula provided by the invention, by changing the compositions and the ratio of raw materials and adding a crosslinking agent, the smooth finish of the waterproof TPU film can be improved and particulate matters in a TPU film are eliminated; in addition, structural tightness and stability of raw materials can be ensured and the waterproof effect is improved; by improving the processing technology, the process is simplified, heat supply operation is facilitated, and the production cost is effectively reduced, so that the use stability can be greatly improved and the smoothness of production and processing is ensured.

Description

technical field [0001] The invention relates to the field of film technology, in particular to a waterproof TPU film process and formula. Background technique [0002] TPU is a polymer polymerized by polymer compounds. It is widely used in industry and industrial production, and its development has been very rapid in recent years. [0003] The sub-chain of TPU is generally composed of hard segment and soft segment. The soft segment is generally hydroxyl-terminated polyether, polyester and polyolefin, etc. The hard segment is generally formed of polyurethane by chain extender and isocyanate. Various industries such as medical treatment and chemistry, but the existing TPU material film cannot guarantee its waterproof performance in the material ratio. In high-demand industries, the stability of the product is poor. The production cost is increased, and it is also inconvenient to control during the production process, which is not conducive to the operation of workers and affe...
