Embodiment 1

[0022] Embodiment 1: environmental protection colorless and transparent PVC sheet, the component and content of raw material are as shown in table 1, and the unit of each component in table 1 is kg, and processing aid is 6-methyl coumarin, antioxidant It is bisphenol A, the heat stabilizer is butyl tin, the filler is talcum powder, and the lubricant includes 2kg calcium stearate and 2kg paraffin.

[0023] The production process of the environmentally friendly colorless and transparent PVC sheet is as follows, step 1, batching, taking each component in the raw material, heating to 85°C, and stirring evenly. Step 2, extruding, cooling the material in step 1 to 50°C, feeding it into an extruder for extrusion, controlling the heating temperature of the extruder at 140-150°C, and controlling the plasticizing temperature of the material at 150-180°C. Step 3, calendering, the material extruded by the extruder is calendered with a calender, and the temperature of the calendering rolle...

Embodiment 2

[0024] Embodiment 2: Environmentally friendly, colorless and transparent PVC sheet. The difference from Embodiment 1 is that the components and contents of the raw materials are as shown in Table 1, and the lubricant includes 1kg calcium stearate and 1kg paraffin.

Embodiment 3

[0025] Embodiment 3: Environmentally friendly, colorless and transparent PVC sheet. The difference from Embodiment 1 is that the components and contents of the raw materials are as shown in Table 1, and the lubricant includes 3kg calcium stearate and 3kg paraffin.

Abstract

The invention discloses an environment-friendly transparent PVC sheet. The PVC sheet comprises the following raw materials in parts by weight: 70-85 parts of polyvinyl chloride; 1-5 parts of diisopropyl cyclohexane-1,2-dicarboxylate; 1-3 parts of a heat stabilizer; 2-4 parts of an antioxidant; 2-6 parts of a lubricant; 2-8 parts of a filler; 1-4 parts of a processing auxiliary agent; 2-4 parts ofsodium hydroxymethyl glycinate; 1-2 parts of polyacrylamide; and 2-3 parts of cetylamine hydrofluoride. The PVC sheet disclosed by the invention has the following advantages and effects: the processing auxiliary agent improves regularity of a polyvinyl chloride crystal, the sodium hydroxymethyl glycinate can also improve the regularity of the polyvinyl chloride crystal, and the sodium hydroxymethyl glycinate and 6-methyl coumarin have a synergistic effect and play a role in improving transparency of the PVC sheet; the cetylamine hydrofluoride destroys a crystal structure of the polyvinyl chloride, and the polyacrylamide is dispersed into the PVC sheet raw material, so that a refractive index of the PVC sheet can be significantly improved, and the effects of improved transparency of the PVCsheet, no color, transparency and environmental protection are achieved.

Description

technical field [0001] The invention relates to the technical field of polymer material preparation, in particular to an environmentally friendly and transparent PVC sheet. Background technique [0002] Polyvinyl chloride (PVC) is a general-purpose resin used in medical, agricultural, manufacturing and other fields. The density of PVC is 1.35-1.45g / cm 3 Among them, it has many advantages, such as better insulation, corrosion resistance, good wear resistance, flame retardancy, and low price. It is a general-purpose resin with a large demand in the world. Colorless and transparent PVC sheet has the characteristics of high light transmittance, corrosion resistance, and good weather resistance. It is a commonly used packaging material in the packaging industry and is widely used in food, medicine, daily life, clothing and other fields. However, polyvinyl chloride products need to add more additives during the preparation process, such as lubricants, stabilizers, cold-resistant ...
