Problems solved by technology

[0003] At present, the high temperature resistance of plastic flanges is usually 60°C, and the low temperature resistance is usually -20°C. However, in real life, for some reason, sometimes the temperature exceeds 60°C or even higher. At this time, ordinary plastic flanges cannot meet the product characteristics. If it is used in severe cold conditions in northern regions, such as Inner Mongolia, Heilongjiang and other regions, the -20°C resistant plastic flange cannot meet the requirements of product characteristics.
Therefore, the current plastic flange has a limited service environment, resulting in a problem of poor service life.

Embodiment Construction

[0008] The invention discloses a plastic flange formula with good temperature resistance, and its raw material composition is: 6-15% of silicon-free polypropylene, 10-18% of 1# oil, and 38-45% of high melting point microcrystalline paraffin. , C9 petroleum resin 6-15%, naphthenic oil 10-18%;

[0009] The silicon-free polypropylene is mainly used as a skeleton material at high temperature, the proportion is 6-15%, but if the silicon-free polypropylene is mixed too much, it will not stick and the sealing performance will be poor!

[0010] The 1# oil is high-viscosity heavy oil, its kinematic viscosity (100°C) ≥ 50mm 2 / s, density (20°C) ≥ 0.94, it can increase the surface viscosity of the product and the filling and bridging effect, the proportion is 10-18%, if it is mixed too much, the softening point temperature of the product will be reduced, and if it is mixed too little, it will affect the viscosity.

[0011] The melting point of the high melting point microcrystalline par...

Abstract

A plastic flange formula with good temperature resistance, characterized in that: the composition of raw materials by weight percentage is: silicon-free polypropylene 6-15%, 1# oil 10-18%, microcrystalline paraffin 38-45%, C9 Petroleum resin 6‑15%, naphthenic oil 10‑18%. By changing the ratio of raw materials in the formula of the plastic flange, the present invention can produce a plastic flange with good temperature resistance. Its high temperature resistance can reach 85°C. After the high temperature performance test, the plastic flange does not melt or deform ;Low temperature resistance reaches ‑40°C, after low temperature performance test, no cracking, no deformation, no bending resistance.

Description

technical field [0001] The invention relates to a plastic flange, in particular to a plastic flange formula with good temperature resistance. Background technique [0002] Plastic flanges are mainly used in the bathroom industry. The connection between the sewage outlet of the lower toilet and the sewage pipe, because the toilet is usually installed in the bathroom, there will be high temperature resistance requirements; Low temperature resistance requirements. [0003] At present, the high temperature resistance of plastic flanges is usually 60°C, and the low temperature resistance is usually -20°C. However, in real life, for some reason, sometimes the temperature exceeds 60°C or even higher. At this time, ordinary plastic flanges cannot meet the product characteristics. If it is used in severe cold conditions in northern regions, such as Inner Mongolia, Heilongjiang and other regions, at this time, the plastic flange resistant to -20°C cannot meet the requirements of prod...
