Abstract

The invention relates to a special material for a preset breakage point loop filter element. The special material comprises the following components in percentage by weight: 88-90% of isotatic polypropylene, 1-2% of calcium stearate, 1-1.5% of benzoyl peroxide, 1-3% of polybutylene, 0.5-1% of a titanate coupling agent, 1-2% of an antioxidant and 0.5-1% of polyhexamethylene adipamide. The special material is high in raising rate, long in woolen fiber, high in woolen fiber strength, high in woolen fiber elastic modus and high in woolen fiber stiffness, and the replacement cycle of the produced filter element is prolonged for 1-2 times.

Description

technical field [0001] The invention relates to a special polypropylene formula, in particular to a special material for a terry filter element with preset breakpoints. Background technique [0002] In the polypropylene resin produced in general industry, the isotactic structure content is about 95%, and the rest is atactic or syndiotactic polypropylene. Industrial products are mainly composed of isotactic substances. Polypropylene also includes copolymers of propylene and a small amount of ethylene. Usually translucent colorless solid, odorless and non-toxic. Due to the regular structure and high crystallization, the melting point can be as high as 167°C. Its outstanding advantages are heat resistance and corrosion resistance, and the products can be sterilized by steam. Low density, is the lightest general-purpose plastic. [0003] Usually, the polypropylene filter element is placed in the primary filter during the water filtration process. Due to the poor quality of ...
