preparation example Construction

[0011] The invention discloses a preparation method of an anti-corrosion plastic bag, comprising: 1) mixing and heat-treating raw materials to obtain a mixture; 2) extruding the mixture to obtain an anti-corrosion plastic film; 3) making the anti-corrosion plastic film The plastic film is processed into an anti-corrosion plastic bag; wherein the raw materials include polyethylene resin, polypropylene resin, polyurethane, polycarbonate, starch, filler, plasticizer, and stabilizer.

[0012] Relative to 100 parts by weight of polyethylene resin, the amount of polypropylene resin is 10-20 parts by weight, the amount of polyurethane is 10-25 parts by weight, the amount of polycarbonate is 10-25 parts by weight, The dosage of the starch is 10-20 parts by weight, the dosage of the filler is 10-20 parts by weight, the dosage of the plasticizer is 1-5 parts by weight, and the dosage of the stabilizer is 1-5 parts by weight share.

[0013] In the present invention, the molecular weight...

Embodiment 1

[0024] At 20°C, polyethylene resin (weight average molecular weight is 30,000), polypropylene resin (weight average molecular weight is 10,000), polyurethane (weight average molecular weight is 20,000), polycarbonate (weight average molecular weight is 20,000) ), mung bean starch, tapioca starch, sweet potato starch, glass fiber, molybdenum disulfide, hydrotalcite, dibutyl phthalate, aluminum stearate and aluminum stearate (the weight ratio of each substance is 100:11:11 : 10: 3: 3: 5: 4: 4: 2: 2: 1: 1) mixed for 1h, then heat treated at 185°C for 6h to obtain the mixture; then the mixture was extruded at 185°C to obtain the thickness 0.08mm anti-corrosion plastic film; finally the above-mentioned anti-corrosion plastic film is processed into anti-corrosion plastic bag A1.

Embodiment 2

[0026] At 28°C, polyethylene resin (with a weight average molecular weight of 40,000), polypropylene resin (with a weight average molecular weight of 20,000), polyurethane (with a weight average molecular weight of 30,000), polycarbonate (with a weight average molecular weight of 30,000) ), sweet potato starch, potato starch, kudzu root starch, glass fiber, calcium hydroxide, magnesium hydroxide, dioctyl phthalate, calcium ricinoleate and zinc stearate (the weight ratio of each substance is 100:15: 18:20:5:5:5:4:4:7:3:1:2) mixed for 1.5h, then heat treated at 190°C for 5h to obtain the mixture; then extruded the mixture at 190°C A corrosion-resistant plastic film with a thickness of 0.08mm was obtained; finally, the above-mentioned corrosion-resistant plastic film was processed into a corrosion-resistant plastic bag A2.

Abstract

The invention discloses an anti-corrosion plastic bag and a preparation method thereof. The preparation method comprises the steps that 2, raw materials are mixed and subjected to heat treatment to obtain a mixture; 2, the mixture is subjected to extrusion molding to obtain an anti-corrosion plastic film; 3, the anti-corrosion plastic film is processed into the anti-corrosion plastic bag, wherein the raw materials comprise polyethylene resin, polypropylene resin, polyurethane, Makrolon, starch, filling materials, a plasticizer and a stabilizer. The anti-corrosion plastic bag prepared through the method has high corrosion resistance, and is wide in application range, the raw materials in the method are easy to prepare, and mass production can be achieved.

Description

technical field [0001] The invention relates to a plastic bag, in particular to an anti-corrosion plastic bag and a preparation method thereof. Background technique [0002] Plastic bags have become an indispensable part of people's daily life, and are widely used because of their cheapness, light weight, large capacity, and easy storage. At present, plastics are divided into: garbage bags, strain bags, convenience bags, shopping bags, handbags, vest bags, fresh-keeping bags, inner bags of woven bags, gift bags, inner bags of luggage bags, packaging bags, packaging bags and file bags , information bag, etc. [0003] However, for special-purpose plastic bags, the corrosion resistance requirements for acid and alkali resistance are relatively high, and ordinary plastic bags are difficult to meet the requirements. Contents of the invention [0004] The object of the present invention is to provide an anti-corrosion plastic bag and a preparation method thereof. The anti-corr...
