Abstract

The invention discloses an anti-bacterial LDPE plastic. The anti-bacterial LDPE plastic comprises the following components in parts by weight: 160-165 parts of LDPE, 12-18 parts of copper-loaded zirconium phosphate, 10-15 parts of PP maleate, 5-10 parts of brucite, 10-20 parts of magnesium salt whisker, 20-25 parts of jute fiber, 10-13 parts of nano montmorillonite, 5-7 parts of epoxidized soybean oil, 10-20 parts of chitosan-grafted methyl methacrylate and 10 parts of dicumyl peroxide. The anti-bacterial LDPE plastic has a good anti-bacterial function; an obvious anti-bacterial function can be performed when a very small amount of anti-bacterial LDPE plastic is used. Meanwhile, the compatibility between the anti-bacterial LDPE plastic and resins is high; the anti-bacterial LDPE plastic does not migrate in a plastic product, and can not be separated out or extracted from the plastic product. The anti-bacterial LDPE plastic can be dispersed in the plastic product uniformly and easily, and is high in weatherability and durability, so that the plastic product has a long-term antibacterial property.

Description

A kind of LDPE antibiotic plastic

Technical field

The invention belongs to polymeric material field, be specifically related to a kind of LDPE antibiotic plastic.

Technical background

Along with the raising day by day of social development and progress and living standard, people are more and more higher to the requirement of life, Working environment, especially hygienic condition.Because plastics have the advantages such as light weight, not corrosion, good insulating, so will use plastics in a lot of links of household electrical appliances production.But, in daily life, quite a few unwanted bacteria is exist and breed on the surface of plastics, such as: phone, washing machine, computer, refrigerator, electric switch etc., and cause various diseases by contact; Therefore in life, people inevitably will touch the microorganisms such as each bacterioid, mould, all can become bacterial contamination source and pathophoresis source.But along with the continuous enhancing of people to healthy and environmental consciousness, proposed the demand of " antibacterial, sterilization " to contacting household electrical appliance plastic components frequently in daily life, these various household appliances that just require us to use in living have the effect of antibacterial and mouldproof.

Also there is no at present the antibiotic plastic PP Pipe Compound, household electric appliances are all in raw material, to add antiseptic-germicide to prepare antibiotic plastic, its anti-microbial effect is that the slow release by antiseptic-germicide forms, release along with antiseptic-germicide, anti-microbial activity is more and more less, antiseptic-germicide easily lost efficacy and did not reach antibiotic purpose, and antibiotic release can cause the pollution of environment.The product cost made like this is high, quality is unstable, although have antibacterial, antibacterial range is little, the time length is short and there is no the mildew-resistant effect.

Household electrical appliances have a good application prospect with antibiotic plastic, along with the formal appearance of relative national standards GB21551.2-2010 " antibiotic, the degerming of family expenses and similar applications electrical equipment, the particular requirement of purification function anti-biotic material ", antibiotic plastic also will be more wide in the prospect of household electrical appliances market.

Summary of the invention

For above shortcomings in prior art, the object of the invention is to provide a kind of LDPE antibiotic plastic.

The objective of the invention is to be achieved through the following technical solutions: a kind of LDPE antibiotic plastic is comprised of the following weight parts component: 160-165 mass parts LDPE, the copper-loaded zirconium phosphate of 12-18 mass parts, 10-15 mass parts maleinization PP, 5-10 mass parts brucite, 10-20 mass parts magnesium salt whisker, 20-25 mass parts jute fibre, 10-13 mass parts nano imvite, 5-7 part epoxy soybean oil, 10-20 mass parts Graft Copolymerization of MMA onto Chitosan and 10 mass parts dicumyl peroxides.

The beneficial effect that the present invention has: the LDPE antibiotic plastic that the present invention makes has good antibacterial, and consumption seldom just can obviously play anti-microbial effect; To get well with the consistency of resin, do not move in plastics, do not separate out, be not extracted simultaneously; In plastics, be easy to be uniformly dispersed, good weatherability, persistence is good, makes plastics have long-term germ resistance.

Embodiment

Example of the present invention is can not limit the present invention to explanation of the present invention, in the implication suitable with the present invention and any change and the adjustment in scope, all should think within the scope of the invention.

embodiment 1

The preparation of LDPE antibiotic plastic: by 160-165 mass parts LDPE, the copper-loaded zirconium phosphate of 12-18 mass parts, 10-15 mass parts maleinization PP, 5-10 mass parts brucite, 10-20 mass parts magnesium salt whisker, 20-25 mass parts jute fibre, 10-13 mass parts nano imvite, 5-7 part epoxy soybean oil, 10-20 mass parts Graft Copolymerization of MMA onto Chitosan and 10 mass parts dicumyl peroxides mix puts into stirrer, put into twin screw extruder after stirring and plastify granulation, temperature is 195 ℃, 200 ℃, 205 ℃, 210 ℃, 205 ℃, screw speed is 60r/min, injection moulding process machine-shaping batten for pellet, the salient features that temperature is the material prepared of 170 ℃, 185 ℃, 195 ℃, 190 ℃ the present embodiment is as follows: tensile strength MPa(GB/T1040-2006): 34, and elongation at break %(GB/T 1040-2006): 15-16, shock strength kJ/m ²(GB/T1043-2008): 3.0-3.3, flexural strength MPa(GB/T9341-2000): 46-48, through the experiment of industry internal standard, detect, result is as follows: colibacillary 24 hours sterilizing rates are reached to 97.6%, 24 hours sterilizing rates to streptococcus aureus reach 99.2%.

Claims

1. a LDPE antibiotic plastic, is characterized in that being comprised of the following weight parts component: 160-165 mass parts LDPE, the copper-loaded zirconium phosphate of 12-18 mass parts, 10-15 mass parts maleinization PP, 5-10 mass parts brucite, 10-20 mass parts magnesium salt whisker, 20-25 mass parts jute fibre, 10-13 mass parts nano imvite, 5-7 part epoxy soybean oil, 10-20 mass parts Graft Copolymerization of MMA onto Chitosan and 10 mass parts dicumyl peroxides.
