Description

A kind of anti-rot plastic container

Technical field

The present invention relates generally to plastic applications, particularly relates to a kind of anti-rot plastic container.

Background technology

Plastic containers are seen everywhere in life, bucket, bottle, tank, cup etc., because it is of many uses, throw-out also gets more and more, inevitable pollution is caused to environment, the plastic containers simultaneously had need the chemical products holding different performance, and some chemical productss can cause certain erosion to plastics itself, not only have a strong impact on the purity of chemical products, also easily cause danger in various degree, some plastic containers easily distribute toxic gas under burning or hot environment, the safety of harm surrounding population, in order to improve the defect of conventional plastic container each side, therefore reasonable disposition plastic formula composition is needed, add waste-tyre rubber-powder simultaneously, make full use of Resource recovery, reduce production cost, improve the integrated quality of finished plastic containers.

Summary of the invention

The object of the invention is just to provide a kind of anti-rot plastic container.

The present invention is achieved by the following technical solutions:

A kind of anti-rot plastic container, is characterized in that what it was made up of the raw material of following weight parts:

Described fluoridize that sizing material is made up of the raw material of following weight parts:

Ten difluoro heptyl propyl trimethoxy silicane 2-3, waste-tyre rubber-powder 80-90, polyoxyethylene glycol 6-8, aluminium titanates 1-2, diatomite 4-6, ethyl cellulose 16-20, tetracol phenixin 30-41, tributyl citrate 2-3, whiteruss 50-60,2-mercaptobenzothiazole 0.1-0.2;

Polyoxyethylene glycol, ethyl cellulose are mixed to join in tetracol phenixin, ultrasonic vibration 3-5 minute, obtain solution a; Joined by tributyl citrate in whiteruss, after stirring, raised temperature is 80-90 DEG C, drips above-mentioned solution a, dropwises rear insulation reaction 1-2 hour, diatomite is mixed with aluminium titanates, adds after wearing into fine powder, ageing 3-4 hour, press filtration, dry, obtain dry powder;

By waste-tyre rubber-powder, above-mentioned dry powder blend, be heated to 60-65 DEG C, add ten difluoro heptyl propyl trimethoxy silicanes, insulated and stirred 20-30 minute, raised temperature is 150-160 DEG C, add 2-mercaptobenzothiazole, be act on 4-5 minute under the microwave exposure of 2450MHz in microwave frequency, must sizing material be fluoridized.

A preparation method for anti-rot plastic container, comprises the following steps:

(1) by process white, phthalic acid dibutyl ester mixing, insulated and stirred 5-7 minute at 60-70 DEG C, adds the 7-10% of above-specified high density polyethylene weight, and raised temperature is 100-105 DEG C, adds Lauryl Alcohol ester, insulated and stirred 10-20 minute;

(2) by carbic anhydride, Morpan BB, stearic acid, hydroxy silicon oil mixing, insulated and stirred 4-6 minute at 50-60 DEG C, adds and fluoridizes sizing material, stirs;

(3) each raw material after above-mentioned process is mixed with each raw material of residue, join in forcing machine, melt extrude into pipe by forcing machine;

(4) designed still importing at the little pipe of molten state in the mould of definite shape, mould has been closed, and be blown into high-pressure air simultaneously and make it according to the mould molding set, simultaneously to mold cools down sizing, then started the goods that die cavity has been shaped.

Advantage of the present invention is:

Of the present inventionly fluoridize sizing material: the present invention is by polyoxyethylene glycol, the carbon tetrachloride solution of ethyl cellulose joins in whiteruss, because tetracol phenixin is easy to spread in whiteruss, be separated, add diatomite in powder, aluminium titanates, can be formed by alcohol, Mierocrystalline cellulose, soil powder, the height mixture of aluminium titanates composition, give mixture good thermostability simultaneously, thermoplasticity, anti-old property etc., aluminium titanates can also reduce the thermal conductivity of finished product, improve resistance and high thermal resistance, then mix with waste-tyre rubber-powder and carry out microwave treatment, further increase the anti-aging and anti-caking effect of rubber powder, the ten difluoro heptyl propyl trimethoxy silicanes added can improve electrical insulating property and the resistance to medium of rubber, obtain high strength, high tenacity, resistance rubber powder,

Plastic containers of the present invention have good preservative property, still can place for a long time under the environment such as low temperature and moisture, and weathering resistance is strong, nontoxic pollution-free, and without obnoxious flavour volatilization, over-all properties is superior.
