Problems solved by technology

[0012] The production of PVC transparent material is a complex and highly technical plastic processing process. There are many types of additives involved in the formula (up to a dozen at most), and various additives interact and restrict each other. Therefore, The formula is relatively complicated, especially when faced with 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 transparent compound and a tubular product thereof. By weight percentage, the polyvinyl chloride transparent compound consists of 100 parts of PVC resin, 1.0 to 3.0 parts of stabilizing agent, 0.2 to 1 part of lubricant, 1 to 3 parts of processing modifier, 2 to 5 parts of impact modifier, 0.001 to 0.008 parts of depigmenting agent, 0.2 to 0.6 parts ofageing resistant and 0 to 10 parts of plasticizing agent. The polyvinyl chloride tubular product is prepared by respectively mixing the polyvinyl chloride transparent compound at high temperature withhigh speed and at low temperature with low speed, extruding and forming. The color of the tubular product is bright, transparent and even. The inner wall thereof is smooth so scale is difficult to deposit. The tubular product is convenient to monitor by a system because the inner flow transporting direction and status can be seen clearly. The tubular product can be covered on pipeline for transporting important or dangerous chemical products, with a monitor and protection function and an excellent ageing resistance. The invention is applied to outdoors.

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 transparent composition and a pipe thereof. Background technique [0002] Transparent polymer materials refer to polymer materials with a light transmittance of more than 80% in daily light. This type of material has unique optical properties and is widely used in the fields of optical components, packaging, construction, medical supplies, optical fibers and optical disc materials. widely used. 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. [0003] Polyvinyl chloride (PVC) has a wide range of sources, less investment in equipment, and low prices. The formula can be adjusted...
