Problems solved by technology

[0003] The liquid stabilizers traditionally used for PVC transparent hose mainly include metal salt liquid stabilizers and organotin stabilizers. Due to the limitation of the synthesis process and stability of metal salt liquid stabilizers, the appearance of finished products generally ranges from light yellow to orange red. And it contains a large amount of volatile solvent oil, the production process is prone to produce irritating smoke, and the transparent hose made has a pungent smell; The production process is still made of transparent hose, which smells bad

Abstract

The invention relates to the technical field of heat stabilizer preparation, in particular to a colorless and odorless environment-friendly liquid stabilizer for a transparent hose. The liquid stabilizer comprises the following components in parts by weight: 30-40 parts of a D80 solvent, 5-15 parts of fatty acid, 5-15 parts of aromatic acid, 1-5 parts of zinc oxide, 5-10 parts of calcium hydroxide, 1-5 parts of an antioxidant, 20-30 parts of an auxiliary stabilizer and 1-5 parts of an odor masking agent. Compared with a traditional liquid stabilizer, the liquid stabilizer prepared through preferable material is basically colorless and transparent, meanwhile, the heat-resistant requirement of transparent hose processing is met, activated carbon is introduced for deodorization, a proper amount of smell masking agent is added, so that the liquid stabilizer has less pungent odor, and greenness of the production process and the processed finished product is ensured.

Description

technical field [0001] The invention relates to the technical field of heat stabilizer preparation, in particular to a colorless, odorless and environment-friendly liquid stabilizer for transparent hoses. Background technique [0002] PVC transparent hose can be divided into industrial grade and food grade according to its use. It is widely used in various fields of human production and life such as agriculture, industry, engineering, mines, and petrochemicals. It belongs to plastic products that are in close contact with humans. With the rapid advancement of the world's environmental protection process, the manufacturing standards of these PVC plastic products are getting higher and higher, and non-toxic and tasteless has become its new development direction. [0003] The liquid stabilizers traditionally used for PVC transparent hose mainly include metal salt liquid stabilizers and organotin stabilizers. Due to the limitation of the synthesis process and stability of metal ...
