Problems solved by technology

[0003] However, due to the addition of various additives in the PVC alloy and the influence of the quality of the PVC resin itself, it will have a greater impact on the transparency of the rigid PVC pellets, especially in the injection molding process, because the material will flow through the flow channel at high speed. It produces instantaneous high friction between molecules, and it is easy to cause discoloration or zooming of the material. The general method at this stage is to add a relatively excessive amount of general-purpose internal lubricant (such as: glyceryl stearate) to the material formula to reduce this instantaneous molecular High friction between them, and it is precisely because of this excessive addition of general-purpose internal lubricant that has a great impact on transparency, which severely limits the application range of PVC alloy injection molding products

Description

technical field [0001] The invention relates to a plastic alloy pellet, in particular to a high-strength, high-transparency, heat-resistant hard plastic alloy pellet, which belongs to the technical field of polymer alloy materials. Background technique [0002] As a general-purpose plastic, PVC resin (polyvinyl chloride) is widely used in various food packaging, pharmaceutical packaging, cosmetic packaging, household appliance packaging, auto parts, and chemical materials due to its relatively low price and ease of processing after modification. , architectural decoration building materials, fire equipment accessories, sanitary ware, supermarket shelves and other fields. At present, modified PVC pellets generally have problems such as single product structure, low product grade and low technical content, and their comprehensive performance is far from meeting the ever-changing needs of users in the plastic product production industry, which seriously restricts the developmen...
