Embodiment 1
[0027] A high elastic film, according to the number of parts by mass, its composition comprises: 100 parts of polyvinyl chloride resin, 20-50 parts of rubber powder, 60 parts of filler, 4 parts of stabilizer, 80 parts of plasticizer and 0.5 part of colorant, Wherein, the rubber powder comprises nitrile rubber powder and butyl rubber powder, and the mass ratio of nitrile rubber powder and butyl rubber powder is 5:2.
[0028] The preparation method is as follows:
[0029] After weighing the plasticizer according to the total portion of the formula, get 80% by weight of the plasticizer and add it to the mixer;
[0030] Add the stabilizer and color masterbatch to the mixer at a speed of 800 rpm and stir to dissolve. After weighing the polyvinyl chloride resin according to the number of parts, slowly pour it into the blender, then adjust the speed of the blender to 1400 rpm until all the polyvinyl chloride is dissolved into a paste (no particle emulsion);
[0031] Adjust the spee...
Embodiment 2
[0037] The difference between this embodiment and Example 1 is that the composition of the high elastic film includes: 90 parts of polyvinyl chloride resin, 25 parts of rubber powder, 80 parts of filler, 2 parts of stabilizer, 110 parts of plasticizer and 0.5 parts of colorant Part, wherein, described rubber powder comprises nitrile rubber powder and butyl rubber powder, and the mass ratio of nitrile rubber powder and butyl rubber powder is 5:2.
Embodiment 3
[0039] The difference between this embodiment and Example 1 is that the composition of the high elastic film includes: 110 parts of polyvinyl chloride resin, 45 parts of rubber powder, 20 parts of filler, 6 parts of stabilizer, 65 parts of plasticizer and colorant 0.5 part, wherein, described rubber powder comprises nitrile rubber powder and butyl rubber powder, and the mass ratio of nitrile rubber powder and butyl rubber powder is 5:2.

Abstract
The invention provides a high-elasticity thin film which includes 90-110 parts of PVC resin, 20-50 parts of rubber powder, 10-90 parts of a filling material, 0.5-8 parts of a stabilizer, 55-120 parts of a plasticizer and 0-2 parts of a pigment. The rubber powder includes nitrile butadiene rubber powder and butyl rubber powder according to the mass ratio of (4-6):(1-3). The invention also provides a preparation method of the high-elasticity thin film. By means of optimization on component proportion, the thin film is high in elasticity, high in hardness, high in tensile strength and good in rebound property, has the performances of being insulating and anti-static, being good in sealing performance and weather resistance, and being resistant against acid, alkali and high temperature. The thin film not only can be used in electronic products but also has great application prospect in the fields of machinery and aerospace technology. The high-elasticity thin film is greatly reduced in cost, breaks technical monopoly of foreign products, and filling the technical blank of domestic high-strength and high-elasticity thin films.
Description
technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a high elastic film and a preparation method thereof. Background technique [0002] With the development of new plastic material technology in the field of electronic industry applications, there are more and more application solutions for special high-elastic plastic films in the field of electronics industry, and the prospects are getting better and better. [0003] But at present, this kind of highly elastic plastic film is mainly used in electronic technology. Depending on the thickness of the film, the applicable scope includes: electronics industry, printed circuit board, lithium battery, electroplating, anti-static technology, sealing technology and other fields. It can also be used in large quantities for the outer packaging film of electronic products. [0004] But the production technology has been monopolized by foreign countries. Highly elastic plastic ...
