Problems solved by technology
[0002] Due to the short production cycle, low energy consumption, low cost and the advantages of light weight, high tensile strength, corrosion resistance, good waterproof performance and easy heat sealing of the PVC sandwich membrane material, it is widely used as waterproof materials such as waterproof The manufacture of rain moss cloth, tarpaulin, raincoat cloth, etc. can also be used in the manufacture of inflatable boats, inflatable outdoor products, sports equipment, architectural membranes, etc. Polyvinyl chloride resin is compounded on both sides of the base fabric, but the peel strength between the base fabric fiber itself and the PVC resin is low, and the front and back sides of the PVC sandwich membrane product will be separated from the base fabric fiber after a period of use. Phenomenon, common such as front and back peeling, the whole sheet falling off, etc., resulting in water leakage of waterproof facilities, sports equipment and architectural membrane materials are also easy to peel off and be scrapped during long-term use. This kind of membrane material has a short service life and high cost of use.

Embodiment
[0013] Embodiment: A kind of manufacturing method of high peeling polyvinyl chloride sandwich film material, concrete steps are as follows:
[0014] Step 1: Mix the Ingredients:
[0015] The mixed ingredients are batched according to the scheme in the following table:
[0016]
[0017] in:
[0018] The heat-resistant stabilizer is at least one of liquid barium cadmium zinc stabilizer, barium stearate stabilizer, cadmium stearate stabilizer, and zinc stearate stabilizer;
[0019] Put all the above-mentioned ingredients in a high-speed dispersing mixer and mix evenly, the stirring temperature is 120°C-130°C, and the stirring time is 180s;
[0020] Step 2: Calendering: discharge the uniformly mixed materials into the internal mixer for mixing, the mixing temperature is 130°C-150°C, the mixing time is 200-300s, and then discharged to the open rubber mixer, and then passed through two After the open rubber mixer is masticated for 15 minutes at a temperature of 120°C to 130°C,...

Abstract
The invention discloses a preparation method of a high-peel-strength polyvinyl chloride laminated film material. The method comprises the following steps: uniformly mixing 100 parts of polyvinyl chloride resin, 0-80 parts of an orthophthalic plasticizer, 0-30 parts of a benzene plasticizer, 30-100 parts of a p-benzene plasticizer, 0-40 parts of calcium carbonate, 10-40 parts of magnesium sulfate, 2-5 parts of a heat-resistant stabilizer and 3-5 parts of pigment; mixing, plasticizing, rolling into a sheet, and jointing with base cloth; pasting the base cloth with a paste material consisting of 20-50 parts of polyvinyl chloride resin, 10-50 parts of the orthophthalic plasticizer, 0-10 parts of a diluent, 0-5 parts of a conditioning agent and 0-35 parts of a bridging agent A, drying, and thermally compounding a film and the base cloth to form a laminated cloth product of which both sides are provided with polyvinyl chloride and the middle is provided with the base cloth; performing surface pre-treatment on the front and back sides of a thermally-molded semi-finished product; and heating, embossing, cooling and sizing. The base cloth and the polyvinyl chloride film have extremely high peel strength.
Description
technical field [0001] The invention relates to a method for manufacturing artificial leather, in particular to a method for manufacturing a high-stripping polyvinyl chloride sandwich film material. Background technique [0002] Due to the short production cycle, low energy consumption, low cost and the advantages of light weight, high tensile strength, corrosion resistance, good waterproof performance and easy heat sealing of the PVC sandwich membrane material, it is widely used as waterproof materials such as waterproof The manufacture of rain moss cloth, tarpaulin, raincoat cloth, etc. can also be used in the manufacture of inflatable boats, inflatable outdoor products, sports equipment, architectural membranes, etc. Polyvinyl chloride resin is compounded on both sides of the base fabric, but the peel strength between the base fabric fiber itself and the PVC resin is low, and the front and back sides of the PVC sandwich membrane product will be separated from the base fab...
