preparation example Construction

[0026] A preparation method of laminated painted soft glass, comprising the steps of:

[0027] 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;

[0028] Step 2: Washing and drying, the calendered film is washed with clean water at a temperature of 20-30°C, and then dried with a heating roller at a drying temperature of 120-130°C;

[0029] Step 3: Cooling, using five-roll cooling, the temperatures of the five cooling rolls are 120-150°C, 120-150°C, 120-150°C; 100-120°C, 90-110°C;

[0030] Step 4: coiling and packaging, coiling and packaging the cooled film to obtain PVC film coils;

[0031] Step 5: Stand still, put the PVC film roll at room temperature for 24-48 hours, and the room temperature is 20-30°C;

[0032] Step 6: Composite, composite the static P...

Embodiment 1

[0037] A kind of preparation method of painted soft glass, concrete steps are as follows:

[0038] Step 1: raw material preparation, the raw material formula comprises 100 parts of PVC, 50 parts of plasticizer, 2 parts of stabilizer, 0.6 part of ACR accelerator, 5 parts of colorant according to the quality composition; Dioctyl phthalate, the stabilizer is calcium zinc soap and triphenyl phosphite mixture, the mass ratio of the two is 1:1.

[0039] Step 2: High-speed mixing, each raw material component is measured by a metering device, and then mixed and stirred by a high-speed mixing device, and the temperature of the high-speed stirring is controlled at 100°C;

[0040] Step 3: cooling and stirring, the uniformly mixed composition is stirred by a cooling and stirring device, and the stirring temperature is controlled at 45°C;

[0041] Step 4: banburying, banburying the cooled and stirred composition through a banbury mixer, and controlling the banburying temperature at 160-17...

Abstract

The invention discloses overlying stained soft glass and a preparation method thereof, and belongs to the field of PVC (polyvinyl chloride) thin films. The preparation method includes the steps: washing, drying, cooling, rolling and packaging a rolling thin film to obtain a coiled PVC thin film; performing standing on the coiled PVC thin film at indoor temperature, compounding the coiled PVC thinfilm and a stained thin film, cooling, coiling and packaging a compound to obtain needed stained soft glass product. The overlying stained soft glass has the advantages that repeatedly heating and cooling is implemented, an inner structure of a composition or the thin film is changed in the heating and cooling process, so that inner VOC (volatile organic compounds) are volatilized from the composition, particles of the thin film contract in the washing and cooling processes after rolling, micro-holes are formed in the thin film and can contain parts of water particles, and the VOCs in the thinfilm are evaporated from the inside of the fine film along with moisture in the drying process and greatly reduced.

Description

technical field [0001] The invention relates to the field of PVC films, in particular to a laminated painted soft glass and a preparation method thereof. Background technique [0002] Soft glass, also known as PVC soft crystal board, is a high-quality plastic composite material with smooth, bright and transparent surface, no cracks, no bubbles, and uniform color. It is currently mainly used in electronics, chemistry, pharmaceuticals, food factories, and 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 the use of raw materials and technology, soft glass products will still contain a small amount of VOC volatile organic compounds, which will cause peculiar smell in the application process of soft glass and affect the environmental performance of the product. At present, there are some Research on the reduction of VOC content ...
