Problems solved by technology

But how to control the problem of the water solubility rate of polyvinyl alcohol has not been well solved so far.
[0005] Materials ready for packaging require sterilization. Hydrogen peroxide is a very effective but not particularly stable oxidizing agent, and has the advantage that only a common water by-product is formed, but the half-life of hydrogen peroxide very long, so the sanitizer must be removed after it has done its job

Embodiment 1

[0020] A water-soluble environment-friendly rubber plastic is characterized in that the raw materials are composed as follows according to parts by weight:

[0021] Low-density polyethylene and linear polyethylene are composed of 100 parts of polyethylene, 0.6 parts of iron acetylacetonate, 8 parts of polystyrene, 20 parts of polyvinyl chloride, 4 parts of ethylene terephthalate, and phthalate according to the composition of 3:1. 7 parts of dioctyl formate, 0.1 parts of zinc stearate, 0.2 parts of calcium carbonate, 0.3 parts of paraffin, 0.2 parts of additives composed of 0.18% sulfonated polystyrene sodium salt and 0.5% polyvinyl alcohol according to the composition of 1:4 .

[0022] It is carried out under the condition that hydrogen peroxide is kept in a gaseous state, and the surface of the plastic film is heated to a temperature higher than the dew point of gaseous hydrogen peroxide to sterilize the surface of the water-soluble rubber plastic packaging material.

Embodiment 2

[0024] A water-soluble environment-friendly rubber plastic is characterized in that the raw materials are composed as follows according to parts by weight:

[0025] 100 parts of polyethylene, 0.7 parts of 2-hydroxy-4-methylacetophenone oxime iron, 9 parts of polystyrene, 20 parts of polyvinyl chloride, terephthalic acid 5 ethylene glycol esters, 8 parts of dioctyl phthalate, 0.2 parts of zinc stearate, 0.3 parts of calcium carbonate, 0.4 parts of paraffin, 0.18% sulfonated polystyrene sodium salt and 0.5% polyvinyl alcohol 0.3 parts of additives according to the composition of 1:4.

[0026] It is carried out under the condition that hydrogen peroxide is kept in a gaseous state, and the surface of the plastic film is heated to a temperature higher than the dew point of gaseous hydrogen peroxide to sterilize the surface of the water-soluble rubber plastic packaging material.

Embodiment 3

[0028] A water-soluble environment-friendly rubber plastic is characterized in that the raw materials are composed as follows according to parts by weight:

[0029] Low-density polyethylene and linear polyethylene are composed of 100 parts of polyethylene, 0.8 parts of iron stearate, 10 parts of polystyrene, 20 parts of polyvinyl chloride, 6 parts of ethylene terephthalate, and phthalate in a composition of 3:1. 9 parts of dioctyl diformate, 0.3 parts of zinc stearate, 0.2 parts of calcium carbonate, 0.3 parts of paraffin, 0.18% of sulfonated polystyrene sodium salt and 0.5% of polyvinyl alcohol according to the composition of 1:4 Additive 0.4 share.

[0030] It is carried out under the condition that hydrogen peroxide is kept in a gaseous state, and the surface of the plastic film is heated to a temperature higher than the dew point of gaseous hydrogen peroxide to sterilize the surface of the water-soluble rubber plastic packaging material.

Abstract

The invention discloses water-soluble environment-friendly rubber plastic which is characterized by being prepared from the following raw materials in parts by weight: 100 parts of polyethylene, 0.6-0.8 part of a photosensitizer, 8-10 parts of polystyrene, 20 parts of polyvinyl chloride, 4-6 parts of terephthalic acid gylcol ester, 7-9 parts of dioctyl phthalate, 0.1-0.3 part of zinc stearate, 0.2-0.3 part of calcium carbonate, 0.3-0.4 part of paraffin and 0.2-0.4 part of an additive. Added with a rubber compound, the water-soluble environment-friendly rubber plastic disclosed by the invention has the mechanical properties required by packaging and can realize the aims of clean production and simplification of equipment. By introduction of sulfonic acid groups, the water-soluble environment-friendly rubber plastic has the advantage of being improved in hydrophilia and reduced in surface activation energy and conductive to increasing the water solution rate of a water-soluble plastic film. By vaporization of hydrogen peroxide, a sterilizing effect is achieved; the product quality is improved; an environmental protection function is realized.

Description

technical field [0001] The invention belongs to the technical field of packaging materials, and in particular relates to a water-soluble environment-friendly rubber plastic. Background technique [0002] Packaging materials refer to the materials used to make packaging containers, packaging decoration, packaging printing, packaging and transportation to meet product packaging requirements, including metal, plastic, glass, ceramics, paper, bamboo, wild mushrooms, natural fibers, Main packaging materials such as chemical fibers and composite materials, and auxiliary materials such as coatings, adhesives, strapping tapes, decorations, and printing materials. [0003] At present, water-soluble polyvinyl alcohol film is used as packaging material to replace existing packaging containers. The packaging containers of toxic substances must be disposed of before they can be discarded after use. Due to the increasingly stringent environmental protection requirements recently, the ...
