Problems solved by technology

[0007] The plastic processing process of PVC transparent material is complex and highly technical. There are many types of additives involved in the formula (up to a dozen at most), and various additives interact and restrict each other, so the formula is relatively complicated, especially for noodles. For different types of equipment, different processing conditions and requirements, it is necessary to adopt different formulas and adjust the selection and dosage of each substance in the formula, which requires a lot of work and high cost

Abstract

The invention discloses a polyvinyl chloride composition and a transparent pipe thereof. The polyvinyl chloride composition consists of the following components in part by weight: 100 parts of PVC resin, 1.0 to 5.0 parts of heat stabilizer, 0.2 to 2 parts of lubricating additive, 1 to 3 parts of processing modification aid, 2 to 5 parts of impact modifier, 0.01 to 0.08 part of decolorizing agent, 0.2 to 0.6 part of age resister and 0 to 10 parts of plasticizer. The polyvinyl chloride composition is subjected to high-speed hot mixing and low-speed cold mixing, and then is extruded to prepare the polyvinyl chloride transparent pipe; and the pipe is homogenous and transparent, has smooth inner wall, is not easy to scale, can be sleeved outside a pipeline for delivering important or dangerous chemicals, has monitoring and protecting functions, has good ageing resistance, and can be used for outdoor occasions. The preparation method for the polyvinyl chloride transparent pipe is simple, convenient and quick, does not require special tools and professional staff, and is favorable for large-scale industrial production.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to the technical field of transparent materials, in particular to a polyvinyl chloride composition and a transparent pipe thereof. Background technique [0002] Transparent polymer materials refer to polymer materials with a light transmittance of more than 80% in daily light. They have unique optical properties and are widely used in many fields such as optical components, packaging, construction, medical supplies, optical fibers and optical disc materials. . [0003] The currently commonly used transparent materials are mainly engineering plastics such as PC, PET, PS, PMMA, etc., which are expensive and are mainly used in optical lenses, glass products, packaging containers, etc. There is even less aging transparent tubing. [0004] Polyvinyl chloride (PVC) has a wide range of sources, less investment in equipment, and low prices. The formula can be adjusted according ...
