Abstract

The invention discloses a shell body material of an automobile cooling pump. The shell body material is prepared from the following raw materials in parts by weight: 30 to 60 parts of high density polyethylene, 3 to 7 parts of dicumyl peroxide, 3 to 7 parts of clay, 4 to 6 parts of carbon black, 10 to 20 parts of modified natural wood fiber, 20 to 30 parts of phenolic resin, 2 to 4 parts of color master batch, 2 to 4 parts of disproportionated rosin, 2 to 6 parts of pine tar oil, 1 to 2 parts of an antioxidant, 2 to 4 parts of a lubricating agent and 1.5 to 2.5 parts of an antistatic agent. The shell body material of the automobile cooling pump, provided by the invention, has excellent tensile strength, high elongation at break and excellent insulativity and ageing resistance.

Description

technical field [0001] The invention relates to the technical field of cooling pumps, in particular to an automobile cooling pump housing material. Background technique [0002] In the cylinder block of the car engine, there are many water channels for cooling water circulation, which are connected with the radiator placed in the front of the car through water pipes to form a large water circulation system. A water pump is installed at the upper water outlet of the engine. Driven by the fan belt, the hot water in the water channel of the engine cylinder is pumped out and the cold water is pumped in. There is also a thermostat next to the water pump. When the car is just started, it is not opened, so that the cooling water does not pass through the water tank, but only circulates in the engine. When the temperature of the engine reaches above 95°C, it is opened, and the hot water in the engine is pumped. When the car enters the water tank, the cold wind blows through the wat...
