Problems solved by technology

PVC film generally refers to soft PVC, which is widely used in plastic 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 use range is limited

Embodiment 1

[0025] 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 , 2 parts of vinylated methyl methacrylate resin, 1 part of ricinoleic acid triethanolamine borate.

[0026] The above-mentioned plasticizer is a mixture of dioctyl phthalate and di(2-propylheptyl) phthalate in any proportion.

[0027] The above-mentioned heat stabilizer is a mixture of barium stearate and zinc stearate in a mass ratio of 1:1.

[0028] Above-mentioned lubricant is the mixture of calcium stearate polyethylene wax compound, paraffin.

[0029] 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; raise the temperature of the system to 100-120°C , set the stirring speed to 1...

Embodiment 2

[0031] 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 talcum powder, 1.5 parts of heat stabilizer, 1.3 parts of lubricant, 1 part of softener, 2 parts of vinylated methyl methacrylate resin, and 1.5 parts of triethanolamine borate.

[0032] 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.

[0033] The above heat stabilizer is a mixture of barium stearate, zinc stearate and chromium stearate in a mass ratio of 1:1:0.5.

[0034] The above lubricant is a mixture of calcium stearate polyethylene wax compound and po...

Embodiment 3

[0036] 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, 2 parts of vinylated methyl methacrylate resin, 1.5 parts of triethanolamine borate.

[0037] Above-mentioned thermal stabilizer is the mixture of calcium stearate, zinc stearate in any mass ratio.

Abstract

The invention relates to a clear and transparent soft PVC film which is prepared from the following raw materials in parts by mass: 100 parts of PVC resin, 1 to 7 parts of a plasticizer, 10 to 20 parts of a filler, 1.5 to 3 parts of a thermal stabilizer, 0.5 to 2 parts of a lubricating agent, 1 to 2 parts of a softener, 1 to 2 parts of vinyl methyl methacrylate resin, and 0.5 to 1.5 parts of a surfactant, wherein the surfactant is boric acid ester. The raw material configuration is improved; the added vinyl methyl methacrylate resin can obviously improve the transparency of the film; by the further adding of the surfactant and the cooperation with a rinsing process for the PVC film, the high-transparency PVC film is obtained.

Description

technical field [0001] The invention relates to the technical field of PVC film preparation, in particular to a PVC film with good clarity and transparency 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 in plastic 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 use The scope is limited. 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] The continuous development of PVC films with better transparenc...
