Description

A kind of antifog material and preparation method thereof
Technical field
The invention belongs to Material Field, relate in particular to a kind of antifog material and preparation method thereof.
Background technology
Polyethylene (PE) is a kind of thermoplastic resin, and odorless, nontoxic has good resistance to low temperature, and chemical stability is good, the erosion of the most of soda acids of ability.Just because of polyethylene has as above speciality, and easily machine-shaping, therefore polyethylene is applicable to the higher Product labellings of performance such as water resistant, oil and chemical substance.Due to the flexibility of PE excellence, be particularly useful for plastics bag again, also can be used for can not using because of environmental requirement the situation of PVC label material.
Polyethylene itself is a kind of water white material, has more application in the field that much needs transparent material, although polyethylene itself water insoluble, water vapor still can be enriched in polyethylene surface, thereby affects the transparency of material.
Summary of the invention
The object of the invention is to provide a kind of antifog material and preparation method thereof, makes antifog material and not only has good mechanical property and workability, has good anti-fog performance and ageing resistance simultaneously.
Object of the present invention can be achieved through the following technical solutions:
A kind of antifog material, mainly made by the component that comprises following weight part:
Low Density Polyethylene 90-100 part,

Pentanedioic acid 5-8 part,
Dispersion agent 2-5 part,
Antifogging agent 6-12 part,
Oxidation inhibitor 1-2 part.
Described antifogging agent is the mixture of the two stearates of glycerine fatty acid methyl esters, sorbyl alcohol and glyceryl monoacetate.
In described antifogging agent, the mass ratio of glycerine fatty acid methyl esters, the two stearates of sorbyl alcohol and glyceryl monoacetate is 3:2:1.
Described dispersion agent is ethylene group bis-stearamides or sodium laurylsulfonate; Described oxidation inhibitor is antioxidant 1076.
A preparation method for antifog material, the method comprises the following steps:
(1) Low Density Polyethylene 90-100 part, polycarbonate 20-30 part, polyethylene wax 8-10 part, pentanedioic acid 5-8 part, dispersion agent 2-5 part, antifogging agent 6-12 part and oxidation inhibitor 1-2 part;
(2) above-mentioned raw materials is put into high-speed mixer and fully mixed, with metering material conveying device, mixed material is sent in twin screw extruder, through the shearing action of screw rod, sufficient mixing, extrude granulation;
Described in step (2), the each zone temperatures of dual-screw-stem machine is 160-250 ℃.
Beneficial effect:
By having added in polyethylene, this mechanical strength of polycarbonate is good in the present invention, good toughness, transparent material, makes resulting materials combine the excellent properties of polyethylene and polycarbonate; Meanwhile, the present invention has added antifogging agent especially, makes the material making have antifog characteristic, aspect the selection of antifogging agent and the amount of interpolation two, is being studied, and makes to add the effect of mixed antifogging agent best.In order to make the performance of material more stable and even, the present invention has also added the raw material such as pentanedioic acid and polyethylene wax, when the mixing of these materials makes final product have good mechanical strength and toughness after adding, also has antifog, age inhibiting effect simultaneously.
