Abstract

The invention discloses a preparation technology of an environment-friendly chlorohydrin rubber. The preparation technology is realized by a formula and a preparation process flow. In the preparation technology, combination of environment-friendly magnesium oxide, calcium carbonate and a 2,4,6-trithiol thiotriazine vulcanizing system is adopted to substitute combination of lead tetraoxide and a 1,2-ethidenethiourea vulcanizing system, which is matched with a technical proposal of the corresponding formula and the corresponding preparation process, thus avoiding the problems of toxicity, harmfulness and environmental pollution as well as not meeting ELV directive requirements in the prior art. Temperature-resistant and oil-resistant rubber products which are made from the environment-friendly chlorohydrin rubber prepared by the preparation technology of the environment-friendly chlorohydrin rubber are nontoxic, harmless and environmental friendly, and meet the ELV directive requirements on the premise of meeting various mechanical strength indexes and physicochemical indexes.

Description

technical field [0001] The invention relates to the preparation of a temperature-resistant and oil-resistant rubber, specifically refers to the preparation technology of an environment-friendly chloroether rubber prepared by using an environment-friendly vulcanizing agent and used for manufacturing rubber products such as automobile rubber hoses. Background technique [0002] Chlorine ether rubber is widely used in the manufacture of rubber products such as automobile jet pipes and sensor sealing rings. The vulcanization system of the epichlorohydrin rubber in the prior art is the combination of trilead tetroxide and 1,2-ethylene thiourea. Trilead tetroxide contains the harmful substance "lead" banned in the ELV directive, so there are poisonous, harmful, unsafe Environmental protection and non-compliance with the requirements of the ELV directive. Contents of the invention [0003] Aiming at the problems and deficiencies in the above-mentioned prior art, the present inve...
