A kind of polytetrafluoroethylene propylene and preparation method thereof

Abstract

The invention discloses a polytetrafluoroethylene propylene and a preparation method thereof. (1) first decompose 70-75% polytetrafluoroethylene propylene into lumps or powder ink; (2) the 70-75% polytetrafluoroethylene obtained in step (1) % PTFE and 5-10% polyhexafluoropropylene oxide, 3-5% softener, 1-2% brightener, 1-2% calcium powder, 0.1-0.5% pigment, 2-5% Add lubricant, 3-5% flame retardant and 5-10% reinforcing agent into the mixer at the same time, and stir evenly until the temperature of the mixer reaches 80°C-100°C, then add 1-3% stabilizer; (3) The raw materials of the gained step (2) are put into a granulator to form granules to obtain polytetrafluoroethylene propylene. The present invention basically reduces the production cost in the existing ones, replaces the existing expensive new materials, and simultaneously achieves Easy to shape, easy to bend, suitable hardness, simple molding conditions, can achieve a more ideal effect, so as to update the follow-up products and promote the development of production.

Description

technical field [0001] The invention relates to the technical field of chemical engineering, in particular to a polytetrafluoroethylene propylene and a preparation method thereof. Background technique [0002] The traditional PTFE is prepared by using 85% PTFE and 15% polyhexafluoro. This production method has high production costs and will bring many unfavorable factors to the products after production, such as the product is too hard , It is not easy to bend, and it is not easy to shape. It needs to use large-scale equipment to make it shape at a higher temperature, which increases the production equipment and increases the production cost. At the same time, the color is relatively single. Contents of the invention [0003] In order to overcome the above-mentioned deficiencies existing in the prior art, the purpose of the present invention is to provide a softer, more flexible polytetrafluoroethylene propylene. [0004] In order to achieve the above object, the present ...
