Embodiment 1

[0021] The raw materials of the PVC substrate described in this embodiment are: 100 parts by mass of PVC (SG-7), 20 parts by mass of ESO plasticizer, 5 parts by mass of copolyether diamine (HK-511 of Huntsman Company), 3 parts by mass of barium stearate, 3 parts by mass of dimethylaminoethyl methacrylate, 5.0 parts by mass of hydroxy-terminated styrene-butadiene liquid rubber, 1.5 parts by mass of hydroquinone dihydroxyethyl ether, 2 parts by mass of parts of titanium dioxide, 5 parts by mass of barium sulfate, 1.2 parts by mass of antioxidant JY-1010, and 1.0 parts by mass of light stabilizer 944. The production of the PVC resin insole includes the following steps: (1) stirring and mixing the raw materials evenly, the stirring temperature is 130°C, and the stirring time is 10 minutes; (2) discharging the uniformly mixed materials into an internal mixer for mixing, The mixing temperature is 150°C, and the time is 35 minutes; (3) inject the mixed material into the mold, and the...

Embodiment 2

[0024] In this embodiment, the mass ratio of the first polyurethane component to the second polyurethane component in the treatment liquid is 2:1. The first polyurethane component is prepared by the following steps: 10 parts by weight of TDI, 3 parts by weight of polytrimethylene ether glycol (Cerenol H series of DuPont Company of the United States), 2.0 parts by weight of 1,4-butanediol alcohol, 1.8 parts by weight of polymer polyol, and 0.1 parts by weight of dibutyltin dilaurate were mixed, and then reacted at 80°C for 1.5 hours; after the reaction solution was cooled to room temperature, 30 parts by weight of deionized water and 1.0 parts by weight of The sodium lauryl sulfonate is stirred and dispersed to obtain the first polyurethane component. The second polyurethane component is prepared by the following steps: 10 parts by weight of XDI, 3 parts by weight of polytetrahydrofuran diol, 2.0 parts by weight of 1,4-butanediol, 1.8 parts by weight of polyallylamine resin (P...

Embodiment 3

[0026]In this embodiment, the mass ratio of the first polyurethane component to the second polyurethane component in the treatment liquid is 3:1. The first polyurethane component is prepared by the following steps: 12 parts by weight of TDI, 4 parts by weight of polytrimethylene ether glycol (CerenolH series of DuPont Company of the United States), 2.5 parts by weight of 1,4-butanediol alcohol, 2.0 parts by weight of polymer polyols, and 0.1 parts by weight of dibutyltin dilaurate were mixed, then reacted at 80°C for 1.5 hours; after the reaction solution was cooled to room temperature, 30 parts by weight of deionized water and 1.0 parts by weight of The sodium lauryl sulfonate is stirred and dispersed to obtain the first polyurethane component. The second polyurethane component is prepared by the following steps: 12 parts by weight of XDI, 4 parts by weight of polytetrahydrofuran diol, 2.5 parts by weight of 1,4-butanediol, 2.0 parts by weight of polyallylamine resin (PAA-01...

Abstract

The invention relates to a PVC resin insole and a preparation method thereof. The resin insole includes a PVC base material, and a polyurethane skin layer is formed by coating a treatment liquid on the PVC base material and solidified; and the treatment liquid is formed by the first A treatment fluid consisting of a polyurethane component and a second polyurethane component. In the PVC resin insole of the present invention, the polyurethane skin layer has excellent bending performance and wear resistance on the basis of ensuring soft and comfortable use performance. The PVC substrate used is not only soft and comfortable, but also has excellent anti-aging performance.

Description

technical field [0001] The invention relates to the technical field of daily necessities processing, more specifically, the invention relates to a PVC resin insole and a preparation method thereof. Background technique [0002] Polyvinyl chloride, referred to as PVC in English (Polyvinylchloridepolymer=PVC molecular structure), is a thermoplastic resin polymerized by vinyl chloride under the action of an initiator. It is a homopolymer of vinyl chloride. Vinyl chloride homopolymers and vinyl chloride copolymers are collectively referred to as vinyl chloride resins. PVC resin has been widely used in industry and daily life; in daily necessities, plastic sandals, shoe soles, insoles, slippers, etc. can be made by using injection molding machines with various molds. However, the polyvinyl chloride shoe material used in the prior art has high hardness and is uncomfortable to wear; while the soft polyvinyl chloride has poor weather resistance, and its brittleness gradually incre...
