Problems solved by technology

Conventional PVC inkjet film, under the condition of high temperature above 60 ℃, the plasticizer is easy to precipitate, which will cause poor ink absorption and cause the inkjet picture to be unclear
At the same time, due to the influence of temperature, PVC inkjet film is easy to shrink
It is easy to shrink the edge after gluing and use. In severe cases, it will cause curling and greatly affect its appearance and use.

Embodiment 1

[0020] Embodiment 1: a kind of production formula of high temperature-resistant PVC spray-painted film, in parts by weight:

[0021]

[0022]

Embodiment 2

[0023] Embodiment 2: the production prescription of another kind of high-temperature-resistant PVC spray-painted film, by weight:

[0024]

[0025] A method for making a high temperature resistant PVC spray-painted film:

[0026] Put the raw materials of the formula in Example 1 in parts by weight into a high-speed mixer and stir for 300 seconds, and control the temperature at 115°C; then put them into a low-speed cold mixer and stir until the temperature reaches 65°C, and then put them into a planetary machine for closed plasticization , the temperature of the main screw is controlled at 180°C, and the temperature of M1 is controlled at 185°C; then the material is moved to the double-roller rolling machine A for further plasticization, and the temperature is controlled at 200°C, and then the impurities are filtered through the filter, and the filter mesh is 200 mesh , The temperature of the filter is 170°C. After filtering, the material is put into the double-roller rolli...

Abstract

The invention discloses a production formula of a high-temperature-resistant PVC painting film and a preparation method thereof. The production formula is characterized in that the high-temperature-resistant PVC painting film is prepared by adding the following raw materials in parts by weight: 22 to 34 parts of plasticizers, 1 to 3 parts of epoxidized soybean oil, 2 to 4 parts of stabilizing agents, 5 to 20 parts of filling agents, 0.3 to 0.8 part of ultraviolet absorbent, 0.3 to 0.5 part of antioxidants, 1 to 3 parts of processing auxiliary agents, 8 to 15 parts of titanium dioxide and 0.05to 0.3 part of pigments into per 100 parts of PVC resin. The preparation method comprises the following steps of proportioning, mixing, planetary machine plasticizing, A milling machine plasticizing,filtering, B milling machine heat insulation material feeding, calendaring shaping, pattern pressing, cooling, edge cutting, reeling and packaging. The PVC painting film has good painting performance,and achieves high-temperature separation resistance and high-temperature shrinkage resistance; the definition of the painting images can be maintained; the edge shrinkage cannot easily occur after the painting; the use and the attractive appearance cannot be influenced; the service life is longer.

Description

technical field [0001] The invention relates to the field of spray-painting materials, in particular to a production formula and a preparation method of a high-temperature-resistant PVC spray-painting film. Background technique [0002] The advertising industry is developing day by day, and the requirements for inkjet materials are getting higher and higher. Conventional PVC inkjet film, under the condition of high temperature above 60 ℃, the plasticizer is easy to precipitate, which will cause poor ink absorption and cause the inkjet picture to be unclear. At the same time, due to the influence of temperature, PVC inkjet film is easy to shrink. It is easy to shrink the edge after gluing and use. In severe cases, it will cause curling and greatly affect its appearance and use. How to develop a PVC inkjet film with good inkjet performance, high temperature resistance to precipitation, and high temperature shrinkage resistance is very necessary.
