Abstract

The invention discloses a special liquid calcium-zinc stabilizer of PVC (Polyvinyl Chloride) gloves. The liquid calcium-zinc stabilizer comprises the following raw materials in parts by weight: 100 parts of calcium laurate, 10-50 parts of zinc laurate, 5-10 parts of nano-montmorillonite, 5-10 parts of nano-silica, 5-10 parts of polyethylene wax, 2-10 parts of carbon nano tube modified polyphosphazene-polyether sulfone segmented copolymer, 5-9 parts of tetra[beta-(3,5-di-tert-butyl-4-hydroxyphenyl) propionate]pentaerythritol ester, 5-8 parts of an ultraviolet light absorber UV-9, 5-10 parts ofdiethylene glycol monobutyl ether, 1-10 parts of beta-diketone and 1-5 parts of sulfonated polyphosphazene modified nanometer titania. The special liquid calcium-zinc stabilizer of PVC gloves disclosed by the invention is excellent in weather resistance and unlikely to discolor, so that the service life of the PVC gloves can be prolonged, and the mechanical strength and heat resistance of the PVCgloves can be greatly improved. The liquid calcium-zinc stabilizer has the characteristic of environmental friendliness.

Description

technical field [0001] The invention belongs to the technical field of chemical stabilizers, and more specifically, the invention relates to a special liquid calcium-zinc stabilizer for PVC gloves and a preparation method thereof. Background technique [0002] With the development of modern technology, more and more gloves are used. As the main material of gloves, polyvinyl chloride (PVC) material is in increasing demand. In the prior art, in the process of preparing PVC gloves, it is usually necessary to add a stabilizer to improve performance. Usually, a non-toxic calcium-zinc composite stabilizer is generally used, which is a non-toxic, environmentally friendly heat stabilizer recognized worldwide, and has the advantages of low price and good lubricity. However, the calcium-zinc composite stabilizers currently on the market, on the one hand, have poor weather resistance and are prone to discoloration; on the other hand, when the added content is high, the strength of PV...
