Problems solved by technology

[0004] Nowadays, most of the PVC resins on the market are used for the processing and preparation of door seals, but most of the existing processing techniques are very cumbersome, and the production efficiency is low. At the same time, the molecular mobility of the prepared PVC door seals is large, and the practicability is not good. high

Embodiment 1

[0076] First of all, before use, you need to start the machine to check the operation of the equipment. At the same time, check the raw materials and weigh each component raw material according to a certain proportion. The raw materials of each component are by weight, 95 parts of PVC resin, 55 parts of plasticizer, and 50 parts of heavy calcium carbonate. 1 part, 7 parts of calcium zinc stabilizer, 1 part of stearic acid, 0.5 part of inorganic pigment, 0.2 part of foaming regulator; the plasticizer is 15 parts of trioctyl trimellitate (TOTM) and 30 parts of epoxy resin Soybean oil (ESO) blends;

[0077] Then put the weighed PVC resin and calcium-zinc stabilizer into a high-speed mixer for stirring, and when the temperature reaches 70°C after high-speed stirring, add plasticizer, heavy calcium carbonate, stearic acid, inorganic pigment and foaming adjustment Put the agent into the high-speed mixer, and stop stirring when the temperature reaches 110°C; then put the stirred mate...

[0083] First of all, before use, you need to start the machine to check the operation of the equipment. At the same time, check the raw materials and weigh each component raw material according to a certain proportion. The raw materials of each component are by weight, 100 parts of PVC resin, 60 parts of plasticizer, and 53 parts of light calcium carbonate. 1 part, 8 parts of barium zinc stabilizer, 1.3 parts of stearic acid, 1 part of inorganic pigment, 0.3 part of flame retardant, 0.3 part of foam regulator; the plasticizer is 20 parts of dioctyl sebacate (DOS) and A blend of 40 parts epoxidized soybean oil (ESO);

[0084] Then put the weighed PVC resin and barium-zinc stabilizer into a high-speed mixer for stirring, and when the temperature reaches 75°C, add plasticizer, light calcium carbonate, stearic acid, inorganic pigment, flame retardant Put the foam regulator into the high-speed mixer, stir until the temperature reaches 115°C, stop stirring; then put the stirred mate...

Embodiment 3

[0090]First of all, before use, you need to start the machine to check the operation of the equipment. At the same time, check the raw materials and weigh each component raw material according to a certain proportion. The raw materials of each component are by weight, 105 parts of PVC resin, 65 parts of plasticizer, and 55 parts of active light calcium. 9 parts, 9 parts of lead salt stabilizer, 1.5 parts of stearic acid, 1.5 parts of inorganic pigment, 0.6 parts of flame retardant, 0.4 parts of foam regulator; of which 25 parts of plasticizer are dioctyl terephthalate (DOTP) and 40 parts of epoxidized soybean oil (ESO);

[0091] Then put the weighed PVC resin and lead salt stabilizer into a high-speed mixer for stirring, and when the temperature reaches 80°C, add plasticizer, active light calcium, stearic acid, inorganic pigment, flame retardant Put the foam regulator into the high-speed mixer, and stop stirring when the temperature reaches 120°C; then put the stirred material...

Abstract

The invention discloses a PVC door gasket with a migration-resisting function and a preparation method thereof. The PVC door gasket is prepared from the raw materials in parts by weight: 90-110 partsof PVC resin, 50-70 parts of a main plasticizer, 50-60 parts of a filling agent, 6-10 parts of a stabilizer, 1-2 parts of a lubricating agent, 0.5-1.5 parts of pigment, 0-0.6 part of a flame retardant, and 0.2-0.4 part of an assistant, wherein a plasticizer is a mixture of the main plasticizer and auxiliary plasticizers, and the main plasticizer is one or more of trioctyl trimellitate (TOTM), dioctyl sebacate (DOS) and dioctyl terephthalate (DOTP). Production efficiency of a first door gasket and a second door gasket is greatly improved, the processing cost is lowered, and meanwhile the molecular migration rate of the first door gasket and the second door gasket is greatly reduced; the PVC door gasket obtained by installing the first door gasket and the second door gasket is reasonable instructure, impact force received during door closing and opening is effectively relieved, airtightness is good, and wide application prospects are achieved.

Description

technical field [0001] The invention relates to the field of PVC door seals, in particular to a PVC door seal with a migration-resistant function and a preparation method thereof. Background technique [0002] Polyvinyl chloride (PVC), a kind of polymer polymerized by vinyl chloride monomer in peroxide, azo compound and other initiators; or under the action of light and heat according to the mechanism of free radical polymerization, because of its relatively Excellent chemical properties, PVC widely appears in our lives. [0003] PVC resin is a thermoplastic polymer compound polymerized by vinyl chloride monomer or ethylene dichloride under the action of an initiator. PVC resin is the basis of polyvinyl chloride plastic. Due to poor thermal stability, PVC resin has poor processability , generally not used alone, need to add various additives to cooperate with the processing, the products made of PVC are widely used. [0004] Nowadays, most of the PVC resins on the market a...
