Problems solved by technology

[0011] The technical problem mainly solved by the present invention is: in the process of traditional plastics, plasticizers are directly added during the processing and use of plastic products, and the plasticizers are prone to migration and loss during the processing and use of plastic products, resulting in the decline and loss of the mechanical properties of plastic products. Plasticizers are easy to cause environmental pollution, and a durable polyvinyl chloride plastic is provided

Embodiment Construction

[0031] Pour the sepiolite into the pulverizer and pass through a 200-mesh sieve after crushing to obtain sepiolite powder, then add the obtained sepiolite powder and hydrochloric acid with a mass fraction of 10-15% in a mass ratio of 1:5-1:10 Put the beaker in the beaker, and then move the beaker into the digital display speed measuring constant temperature magnetic stirrer, under the condition of temperature 75-80 ℃, speed 300-500r / min, heat and stir for 2-3 hours, filter to obtain filter residue, and use deionized water Wash the filter residue 3 to 5 times, then transfer the washed filter residue to an oven, and dry it at a temperature of 105-110°C until it reaches a constant weight, then transfer the dried filter residue to a tube furnace, and dry it at a temperature of 260-110°C. Under the condition of 270°C, roast for 45-60 minutes, cool to room temperature with the furnace, and discharge the material to obtain acid-modified sepiolite, which is the lubricant; in parts by w...

Abstract

The invention discloses durable polyvinyl chloride plastic and belongs to the technical field of high polymer materials. The prepared durable polyvinyl chloride plastic is prepared from polyvinyl chloride, a stabilizer, an antioxidant, a coupling agent, a lubricant and a self-made plasticizer, wherein the self-made plasticizer is prepared by a preparation process comprising steps as follows: firstly, epoxyoleic acid is dissolved in absolute ethyl alcohol, thionyl chloride is added, after a mixture is subjected to constant-temperature stirring reaction, reduced-pressure concentration is performed, ethyl alcohol is recovered, and an acyl chloride product is obtained; after the acyl chloride product, urea, nano graphene oxide, polyvinylpyrrolidone and acetone are mixed, ball-milling reactionis performed, acetone is recovered by reduced-pressure concentration, and the self-made plasticizer is prepared. During plastic processing, firstly, polyvinyl chloride, the stabilizer, the antioxidant, the coupling agent, the lubricant and the self-made plasticizer are mixed uniformly, a mixture is subjected to plastication and extrusion molding, and the durable polyvinyl chloride plastic is obtained. The plasticizer in the prepared durable polyvinyl chloride plastic is stable and difficult to migrate, so that the durable polyvinyl chloride plastic has good mechanical properties during processing and long-term using.

Description

technical field [0001] The invention discloses a durable polyvinyl chloride plastic, which belongs to the technical field of polymer materials. Background technique [0002] A plasticizer is a substance added to a material (usually a plastic, resin or elastomer) to improve its processability, moldability, flexibility and stretchability. Adding a plasticizer can reduce the melt viscosity, glass transition temperature and elastic modulus of the product without changing the basic chemical properties of the plasticized material. [0003] With the rapid development of plastics (especially PVC plastics), rubber, coatings, and synthetic fiber industries, plasticizers have become one of the most important processing aids. In order to make plastics processable and improve the performance of products, various A plasticizer. However, plasticizers added to plastics will be dissolved, migrated, and volatilized during processing and use. On the one hand, they will affect the performance...
