Embodiment 1

[0027] PVC film, raw materials in parts by mass include: 100 parts of polyvinyl chloride resin, 5 parts of plasticizer, filler: 10 parts of calcium carbonate, 8 parts of titanium dioxide, 2 parts of heat stabilizer, 0.5 part of lubricant, and 1 part of softener , 6 parts of methacrylic acid-butadiene-styrene copolymer resin (UNINOX MB-22), 2 parts of vinylated methyl methacrylate resin, 1 part of ricinoleic acid triethanolamine borate.

[0028] The above-mentioned plasticizer is a mixture of dioctyl phthalate and di(2-propylheptyl) phthalate in any proportion.

[0029] The above-mentioned heat stabilizer is a mixture of barium stearate and zinc stearate in a mass ratio of 1:1.

[0030] Above-mentioned lubricant is the mixture of calcium stearate polyethylene wax compound, paraffin.

[0031] The preparation method of PVC film is to preheat polyvinyl chloride resin to 75-85°C, add plasticizer, stir for 60s, add all fillers, stir evenly, and then add the remaining ingredients; r...

Embodiment 2

[0033] The main difference from Example 1 is that the raw materials for the preparation of the PVC film are different. The raw materials for the preparation of the PVC film in this embodiment are measured in parts by mass: 100 parts of polyvinyl chloride resin, 6 parts of plasticizer, and filler: 10 parts of calcium carbonate , 5 parts of titanium dioxide, 5 parts of talc, 1.5 parts of heat stabilizer, 1.3 parts of lubricant, 1 part of softener, 10 parts of methacrylic acid-butadiene-styrene copolymer resin (UNINOX MB-22A), vinyl 2 parts of methyl methacrylate resin, 1.5 parts of triethanolamine borate.

[0034] The above-mentioned plasticizer is diisononyl phthalate mixed with a small amount of chlorinated polyethylene, and the chlorinated polyethylene accounts for 15-20wt% of the total amount of plasticizer added.

[0035] The above heat stabilizer is a mixture of barium stearate, zinc stearate and chromium stearate in a mass ratio of 1:1:0.5.

[0036] The above lubricant i...

Embodiment 3

[0038] The main difference from Example 1 is that the raw materials for the preparation of the PVC film are different. The raw materials for the preparation of the PVC film in this embodiment are measured in parts by mass: 100 parts of polyvinyl chloride resin, 4 parts of plasticizer, and filler: 10 parts of calcium carbonate , 5 parts of talcum powder, 2.5 parts of heat stabilizer, 1.8 parts of lubricant, 2 parts of softener, 12 parts of methacrylic acid-butadiene-styrene copolymer resin (UNINOX MB-22), vinylated methyl methacrylate 2 parts of ester resin, 1.5 parts of triethanolamine borate.

[0039] Above-mentioned thermal stabilizer is the mixture of calcium stearate, zinc stearate in any mass ratio.

Abstract

The invention relates to an ultra-transparent and high-tensile PVC film that is prepared from, by mass, 100 parts of PVC resin, 1-7 parts of plasticizer, 10-20 parts of filling agent, 1.5-3 parts of heat stabilizer, 0.5-2 parts of lubricant, 1-2 parts of softening agent, 2-12 parts of methacrylic acid-butadiene-styrene resin, 1-2 parts of vinylation methyl-methacrylate resin, and 0.5-1.5 parts of surface modifier. The surface modifier is borate surface modifier. The preparation method thereof improves the proportioning of raw materials, which not only significantly improves the transparency of PVC film, but also makes the PVC film more tensile, tear resistant and durable.

Description

technical field [0001] The invention relates to the technical field of PVC film preparation, in particular to an ultra-transparent and high-tensile-strength PVC film and a preparation method thereof. Background technique [0002] The transparency of PVC film is better than that of polyethylene and polypropylene. Common products include plates, pipes, shoe soles, toys, doors and windows, wire sheaths, stationery, etc. PVC film generally refers to soft PVC, which is widely used on floors, ceilings and leather surfaces, but because soft PVC contains softeners (this is also the difference between soft PVC and hard PVC), it is easy to become brittle and difficult to preserve, so its scope of use restricted. Rigid PVC does not contain softeners, so it has good flexibility, easy to shape, not brittle, non-toxic and pollution-free, and has a long storage time, so it has great development and application value. [0003] Continuously developing PVC films with better transparency is ...
