Problems solved by technology

However, due to the low impact strength of PVC at room temperature and easy brittleness, it has the following disadvantages when used as ordinary transparent soft PVC: (1) Plasticizers are easy to migrate and make the toughness and transparency of the material worse; (2) ) The strength of the material is not high; (3) The cold resistance of the material is not good
The powdered nitrile rubber used in this patent is prepared by a synthetic method, the process is complicated, and the control conditions are relatively high.

Abstract

The invention relates to a transparent polyvinyl chloride (PVC) composition and its preparation method. The composition comprises the following blended components: PVC, powdered rubber, an epoxy compound, a stabilizer, and a plasticizer. Specifically, in terms of 100 parts by weight of PVC, the composition includes 0.1-50 parts by weight of the powdered rubber, 0.1-50 parts by weight of the epoxy compound, 0.1-10 parts by weight of the stabilizer, and 5-200 parts by weight of the plasticizer. The powdered rubber is selected from powdered rubber with a crosslinking structure, a gel content of 60wt% or higher, and an average particle size of 20-200nm, and is at least one of nitrile butadiene powdered rubber and carboxyl nitrile butadiene powdered rubber. The transparent polyvinyl chloride composition provided in the invention has high light transmission and low haze, and also has high strength and impact resistance, so that it can be prepared into transparent pipes, profiles, sheets and other products to be used in electrical appliances, automobiles, construction, agriculture, packaging and other fields.

Description

technical field [0001] The invention belongs to the field of modification of polyvinyl chloride, and relates to a transparent polyvinyl chloride composition and a preparation method thereof. Background technique [0002] Polyvinyl chloride (PVC) is a general-purpose plastic with large output, wide application and excellent comprehensive performance. Transparent soft polyvinyl chloride is a versatile material with extremely superior performance and price ratio due to its comprehensive mechanical properties, product transparency, electrical insulation, heat insulation, noise reduction, and shock absorption, and it also has a large application field. , It is used in a large amount in hoses for oil and gas transportation, sealing gaskets, coatings, packaging materials, calendered sheets, automotive interior accessories, and medical products. [0003] With the continuous development of my country's industry, the demand for high-performance PVC transparent materials is increasing...
