[0030] A preparation method of laminated colored painted soft glass, comprising the following steps:

[0031] Step 1: Calendering molding, the PVC main material, plasticizer, stabilizer, accelerator and colorant are passed through a metering device, a high-speed stirring device, a cooling and stirring device, an internal mixer, and a calendering device to obtain a calendered film;

[0032] Step 2: washing and drying, the calendered film is washed with clean water at a temperature of 20-30°C, and then dried on a heating roller at a drying temperature of 120-130°C;

[0033] Step 3: cooling, using five rollers for cooling, the temperatures of the five cooling rollers are respectively 120-150°C, 120-150°C, 120-150°C; 100-120°C, 90-110°C;

[0034] Step 4: coiling and packaging, coiling and packaging the cooled film to obtain a PVC film coil;

[0035] Step 5: let stand, let the PVC film roll stand for 24 to 48 hours at room temperature, and the room temperature is 20 to 30 °C;

Abstract

The invention discloses composite stained soft glass and a preparation method thereof and belongs to the field of PVC films. The preparation method comprises the steps: washing a calendered film with water; drying, cooling, coiling and packing the washed calendered film to obtain a PVC film coiled material; enabling the PVC film coiled material to stand in a room temperature environment; compounding the PVC film coiled material with a stained film; and cooling, coiling and packing the compounded PVC film coiled material and the stained film to obtain the desired stained soft glass product. The composite stained soft glass and the preparation method thereof, disclosed by the invention, have the advantages that interior VOC substances volatilize from a composition by using multiple heating and cooling and changing the interior structure of the composition or the film in the heating and cooling process; in particular, as the water washing and cooling procedures are added after calendering, each particle of the film retracts, so that fine pores are formed in the film and part of water particles can be accommodated; and by using the drying procedure, the VOC volatile substances in the film evaporate from the film along with water, so that the VOC volatile substances in the film are greatly reduced.

Description

technical field [0001] The invention relates to the field of PVC films, in particular to a laminated colored painted soft glass and a preparation method thereof. Background technique [0002] Soft glass, also known as PVC soft crystal plate, is a high-quality plastic composite material with smooth surface, bright and transparent, no cracks, no bubbles, and uniform color. It is currently mainly used in electronics, chemistry, pharmacy, food factories, clothing factories , working platforms, machine surfaces, etc., soft glass has no toxicity and has good flame retardant properties. However, in the actual application process, due to the limitation of raw material use and process, soft glass products still contain a small amount of VOC volatile organic compounds, which will cause peculiar smell during the application process of soft glass, which affects the environmental protection performance of the product. At present, there are some The research is aimed at reducing the VOC ...
