Problems solved by technology

The defects of PVC embossed placemats currently on the market are as follows: 1. The transparency of PVC is not high enough, and the contrast with embossing is not strong enough; 2. The texture of embossed placemats is not clear, and the three-dimensional effect is not strong enough, so it is difficult to improve the product 3. There is a large smell and high toxic content, which is not safe to use
The main reason for the above problems is that the chlorine-containing groups in the PVC resin molecule are extremely sensitive to heat, and the main process of embossing lies in temperature control, and the PVC formula needs to be comprehensively formulated. When the performance is modified, it will affect the transparency of PVC

Embodiment 1

[0047] Prepare a transparent PVC film with a thickness of 0.07mm by the following preparation method:

[0048] Step 1: Weigh the materials according to the proportion. The materials are: 100 parts of PVC resin, 48 parts of dioctyl phthalate, 3 parts of dioctyl adipate, 3 parts of epoxy soybean oil, and 2 parts of barium-zinc composite stabilizer Parts, 0.05 parts of coloring agent, add to the high-speed mixer and mix well.

[0049] Step 2: Send the mixed material to the planetary machine for pre-plasticization, and then send it to the filter for repeated plastication, filtration and plasticization. Filter through stainless steel filter screens of 20 mesh, 60 mesh, 120 mesh, 150 mesh and 200 mesh in turn.

[0050] Step 3: Pass the plasticized material through the metal detector, and then send it to the calender for calendering. The calendering equipment is an inverted L-shaped six-roller calender, and the temperature of each roller is set as follows: No. 1 wheel 170°C, No. 2 ...

Embodiment 2

[0060] A transparent PVC film with a thickness of 0.1mm is prepared by the following preparation method:

The materials are: 100 parts of PVC resin, 43 parts of dioctyl phthalate, 5 parts of dioctyl adipate, 2 parts of epoxy soybean oil, and 2 parts of barium-zinc composite stabilizer Parts, 0.08 parts of coloring agent were added to the high-speed mixer and mixed thoroughly.

[0062] Step 2: Send the mixed material to the planetary machine for pre-plasticization, and then send it to the filter for repeated plastication, filtration and plasticization; filter through 20 mesh, 60 mesh, 120 mesh, 150 mesh, 200 mesh stainless steel filter in turn net filter.

[0063] Step 3: Pass the plasticized material through the metal detector, and then send it to the calender for calendering. The calendering equipment is an inverted L-shaped six-roller calender, and the temperature of each roller is set as follows: No. 1 wheel...

Embodiment 3

[0073] Prepare a transparent PVC film with a thickness of 0.3mm by the following preparation method:

[0074] Step 1: Weigh the materials according to the proportion. The materials are: 100 parts of PVC resin, 50 parts of dioctyl phthalate, 1 part of dioctyl adipate, 3 parts of epoxy soybean oil, and 3 parts of barium-zinc composite stabilizer parts, 0.07 parts of coloring agent, 2 parts of impact modifier ACR, 3 parts of cold-resistant agent dioctyl adipate, add to high-speed mixer and mix thoroughly.

[0075] Step 2: Send the mixed material to the planetary machine for pre-plasticization, and then send it to the filter for repeated plastication, filtration and plasticization. Filter through stainless steel filter screens of 20 mesh, 60 mesh, 120 mesh, 150 mesh and 200 mesh in turn.

[0076] Step 3: Pass the plasticized material through the metal detector, and then send it to the calender for calendering. The calendering equipment is an inverted L-shaped six-roller calender...

Abstract

The invention relates to the technical field of home decoration articles, and particularly relates to a transparent embossing table mat which is prepared from PVC (polyvinyl chloride) resin and an assistant and has a specific formula as follows: 100 parts of PVC resin, 43-50 parts of dioctyl phthalandione, 2-5 parts of dioctyl adipate, 2-3 parts of epoxidized soybean oil, 2-3 parts of barium and zinc composite stabilizing agent and 0.05-0.08 part of coloring agent. The transparent embossing table mat is prepared by adopting the steps: fully mixing materials in a high-speed mixing machine, sending the mixed materials to a planet machine for being preplasticized, then conveying to a filter machine, repeatedly plastifying, filtering and plasticizing, calendaring in a calendaring machine, further plastifying and calendaring the calendered blank to form a film with a certain thickness after continuous calendaring, then introducing the film outside through an introducing roller, drying moisture on the film by warming, coiling to obtain a product, sending the product into a refrigeration house, cooling for 6-8 hours, and discharging outside from the refrigeration house. The transparent embossing table mat has the characteristics of high transparency, good embossing effect, good heat resistance and cold resistance, no toxicity and taste, and environmental friendliness.

Description

technical field [0001] The invention relates to the technical field of home decoration products, in particular to a transparent embossed placemat. Background technique [0002] Polyvinyl chloride (PVC) resin is a non-crystalline, polar polymer with high softening temperature and melting temperature. Generally, it can be plasticized at 160-210 ° C. Due to the polarity between macromolecules The key makes PVC show hard and brittle properties. At present, transparent products made of PVC materials are used in the field of home decoration, and have the advantages of waterproof and anti-corrosion. The defects of PVC embossed placemats currently on the market are as follows: 1. The transparency of PVC is not high enough, and the contrast with embossing is not strong enough; 2. The texture of embossed placemats is not clear, and the three-dimensional effect is not strong enough, so it is difficult to improve the product 3. There is a large smell and high poison content, which is...
