Embodiment Construction
[0028] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0029] In one embodiment of the present invention, weigh according to formula weight percent: 40% polyvinyl chloride resin, 6% organotin stabilizer, 2% stearic acid, 40% epoxidized soybean oil and 12% of calcium carbonate.
[0030] Please refer to figure 1 , which shows a schematic flowchart of the steps of the manufacturing method 1 of the chemical corrosion-resistant polyvinyl chloride strip according to an embodiment of the present invention. According to the above formula to make polyvinyl chloride adhesive strips, the manufacturing method 1 of chemically resistant polyvinyl chloride adhesive strips includes the following steps 101-103:
[0031] Step 101, configure the mixture. Mix polyvinyl chloride resin, organotin stabilizer,...

The invention relates to a formulation of chemical-corrosion resistant polyvinyl chloride rubber strip and a manufacturing method thereof, wherein the formulation comprises the following components in percentage by weight: 40%-50% of a polyvinyl chloride resin; 5%-6% of a heat stabilizer; 2%-3% of a lubricant; 30%-40% of a plasticizer; and 10-15% of a filler. The preparation method comprises the following steps: weighting 40%-50% of polyvinyl chloride resin, 5%-6% of the heat stabilizer, 2%-3% of the lubricant and 10%-15% of the filler, mixing together to form a mixture and stirring at high speed to 70 DEG C; adding 30%-40% of the plasticizer into the mixture, stirring at high speed to 145 DEG C and cooling; and extruding the mixture through an extruder and passing it through an extrusion die to form a polyvinyl chloride rubber strip. The polyvinyl chloride rubber strip prepared by the chemical-corrosion resistant polyvinyl chloride rubber strip formula and the manufacturing method has good elasticity, hardness and corrosion resistance, and can be used as a sealing rubber strip of a mold.
Description
technical field [0001] The invention relates to a polyvinyl chloride rubber strip, in particular to a formula and a production method of a chemical corrosion-resistant polyvinyl chloride rubber strip. Background technique [0002] The sealing strip is a product that seals something so that it is not easy to open, and plays the roles of shock absorption, waterproof, sound insulation, heat insulation, dustproof, and fixation. Sealing strips have multiple materials such as rubber, paper, metal, plastic, etc., but considering cost factors, polyvinylchloride (Polyvinylchloride, PVC) adhesive strips are usually used on the existing market. [0003] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0004] The PVC rubber strips in the prior art usually do not have corrosion resistance, and when they are applied to mold sealing, the chemical liquid inside the mold will corrode the PVC rubber strip...
