Problems solved by technology

The reason is that PVC is prone to yellowing and discoloration during the production process, so it can only be packaged with a colored exterior
With the development of the market, people hope to use pure transparent PVC materials as the base material of table mats, but the traditional PVC materials reduce the transparency of PVC due to the addition of various additives, but the tensile strength of pure PVC materials Degree, toughness and cold and heat resistance can not meet the standard

Abstract

The invention relates to the technical field of preparation of furnace decoration PVC (polyvinyl chloride) films and particularly to a high-definition transparent PVC film and a preparation method of the high-definition transparent PVC film. The PVC film is prepared from the following raw materials in parts by weight: 100 parts of a PVC resin, 1-4 parts of a PVC stabilizer, 1-4 parts of a non-toxic plasticizer, 30-50 parts of a plasticizer, 0-6 parts of a liquid fire retardant, 0-10 parts of an anti-freezing agent, and 0.01-0.02 part of ultramarine toner, the materials are added into a high-speed mixer to be fully mixed, the well mixed materials are conveyed to a planet machine to be pre-plasticized, then the pre-plasticized materials are conveyed to a filter to be repeatedly plasticated, filtered and plasticized, and then conveyed to a calendar for calendaring, the calendared PVC film is cooled in a water tank and unoiled to obtain the PVC film having the advantages of high glossiness, high transparency, excellent thermal endurance and chemical stability and strong tensile strength.

Description

technical field [0001] The invention relates to the technical field of furniture decoration PVC film preparation, in particular to a high-definition transparent PVC film and a preparation method thereof. Background technique [0002] The main component of PVC is polyvinyl chloride, which is light yellow, translucent and shiny. Transparency is better than polyethylene and polypropylene, and worse than polystyrene. Depending on the amount of additives, it can be divided into soft and hard PVC. Soft products are soft and tough, and feel sticky. The hardness of hard products is higher than that of low-density polyethylene. And lower than polypropylene, there will be whitening at the inflection. Common products include plates, pipes, shoe soles, toys, doors and windows, wire sheaths, stationery, etc. It is a polymer material that uses a chlorine atom to replace a hydrogen atom in polyethylene. [0003] The price and cost of PVC are relatively low, and the production process is ...
