Embodiment Construction

[0016] Specific embodiments of the present invention will be further described in detail below. It should be understood that the description of the embodiments of the present invention here is not intended to limit the protection scope of the present invention.

[0017] The environment-friendly calcium oxide pre-dispersion is an environment-friendly calcium oxide pre-dispersion, which includes paraffin and calcium oxide, wherein the paraffin accounts for 40 parts by mass, and the calcium oxide accounts for 60 parts. As we all know, calcium oxide is an inorganic compound, its chemical formula is CaO, and its common name is quicklime. The physical properties of calcium oxide are white particles on the surface, off-white when impure, light yellow or gray when containing impurities, and it has strong hygroscopicity. Calcium oxide reacts with water to form calcium hydroxide (Ca(OH) 2 ) and generate a lot of heat and are corrosive, therefore, they cannot directly contact human ski...

Abstract

The invention relates to an environment-friendly calcium oxide pre-dispersion body and a preparation method thereof. The environment-friendly calcium oxide pre-dispersion body is prepared from the following components in parts by mass: 40 parts of paraffin and 60 parts of calcium oxide. The production process of the environment-friendly calcium pre-dispersion body is performed in a closed container, no pollution is produced for the production environment, and no calcium oxide dust flies in the production process, so that the skin and respiratory tract of operation personnel are not injured. Amain advantage is that the produced environment-friendly calcium oxide pre-dispersion body does not absorb water in a storage process and can be packaged by utilizing an ordinary plastic bag, so thatthe packaging cost can be decreased, the reject phenomenon caused by absorbing the water in the storage process can be avoided, and when being unpacked by a client in use, the environment-friendly calcium oxide pre-dispersion body does not absorb the water in the air. The invention also provided the preparation method of the environment-friendly calcium pre-dispersion body.

Description

technical field [0001] The invention relates to the field of rubber processing, in particular to an environment-friendly calcium oxide predispersion and its preparation method and use method. Background technique [0002] At present, in the production of rubber products, due to the moisture contained in the rubber materials, such as vulcanizing agents, adhesives, and anti-aging agents, air bubbles will be generated during the vulcanization process of the rubber device or semi-finished products, causing the finished product to be scrapped. In order to avoid air bubbles , Calcium oxide is used as a hygroscopic agent in the compound formulation. However, calcium oxide will fly up during the batching process and will be converted into calcium hydroxide when it adheres to the skin of the operator or enters the respiratory tract. Calcium hydroxide is highly alkaline and will seriously damage the skin and respiratory organs of the operator. It is a hazardous chemical. [0003] At...
