Abstract

The invention relates to an antifreeze liquid resisting water pump gasket and a preparation method of the antifreeze liquid resisting water pump gasket. The antifreeze liquid resisting water pump gasket is prepared from a main material and an auxiliary material in parts by weight and is prepared from the following components in parts by weight: 100 parts of the main material, 3 to 15 parts of mica powder, 20 to 30 parts of kaolin, 10 to 20 parts of talcum powder and 5 to 10 parts of a coloring agent; the main material is prepared from an antifreeze liquid resisting hydroxyl silicone oil substance, butadiene styrene rubber and fibers at the mass ratio of (3 to 5) to 40 to (55 to 57); the antifreeze liquid resisting hydroxyl silicone oil substance is prepared from the following components in parts by weight: 30 to 40 parts of hydroxyl silicone oil, 2.5 to 3 parts of a vulcanizing agent, 2 to 3 parts of a vulcanizing accelerant and 1 to 3 parts of an anti-ageing agent. By researching antifreeze liquid, antifreeze liquid resisting materials are pertinently selected; all the raw materials have mutual effect through a special process, so that a prepared sealing gasket has good resilience rate, tensile strength and compression ratio, and also has an excellent antifreeze liquid resisting performance; the weight gain of the sealing gasket is less than 20 percent and the thickening rate of the sealing gasket is less than 10 percent within 22h at the temperature of 100 DEG C.

Description

technical field [0001] The invention relates to an antifreeze-resistant water pump gasket and a preparation method thereof, belonging to the field of sealing materials. Background technique [0002] The temperature in winter is low. In the north of my country, the lowest temperature in winter will be as low as -60°C. Therefore, how to ensure the normal operation of the car engine is a big problem in this extremely bad weather. At present, the most commonly used method is to add some substances that can lower the freezing point of water as antifreeze in the engine coolant to keep the cooling system from freezing in low temperature weather. Antifreeze is a coolant containing special additives, mainly used in liquid-cooled engine cooling systems. Antifreeze has excellent properties such as antifreezing in winter, anti-boiling in summer, anti-scale and anti-corrosion throughout the year. At present, more than 95% of the water-based antifreeze fluids using ethylene glycol at hom...
