Abstract

The invention discloses a drying agent for an automobile brake system and a preparation method thereof. The drying agent is made from the following materials according to parts by weight: 10-15 parts of natural zeolite, 5-10 parts of attapulgite, 8-12 parts of vermiculite, 15-20 parts of clay, 4-8 parts of apatite, 3-6 parts of calcium chloride, 2-5 parts of magnesium sulfate, 1-3 parts of activated alumina, 1-3 parts of borax, and 70-80 parts of a modifier. The drying agent made herein has excellent comprehensive property, has the advantages such as high moisture absorption rate, high moisture absorption speed, high moisture absorbing capacity, zero contact corrosion, zero toxicity and odor and zero environmental pollution, and is low in manufacturing cost, long in service cycle, recyclable, economical and environment-friendly and widely applicable to automobile brake systems.

Description

technical field [0001] The invention relates to a molecular sieve and a preparation method thereof, in particular to a desiccant for an automobile brake system and a preparation method thereof. Background technique [0002] Mineral desiccant is refined from pure natural raw material minerals and a small amount of additives. It is environmentally friendly, non-toxic and tasteless. Mineral desiccants have the functions of adsorption activity, static dehumidification and odor removal, and are widely used in gas drying, food storage, liquid drying, automobile brakes, pharmaceuticals, clothing, military industry, electronics and other fields. [0003] In recent years, with the rapid development of the automobile industry, the performance requirements for mineral desiccants used in automobile brake systems have become higher and higher. Currently, the mineral desiccants used in automobile brake systems on the market cannot meet the requirements. Therefore, it is of great signific...
