Abstract

The invention relates to the technology with plastic waste manufacturing paint, it may further comprise the steps: clean polystyrene plastic is added be equipped with in the container of benzene, make it all dissolvings and be gluey; Gasoline or kerosene are added in another container of dress dimethylbenzene; After solution in above-mentioned two containers mixed, add rosin or pitch, add oil-soluble colourant after the dissolving again; Add a small amount of Zinic stearas at last, pressure filtration behind the uniform mixing.What this manufacturing technology had solved waste or used plastics utilizes problem again, and less investment, and production cost is low.

Description

Technology with plastic waste manufacturing paint

The present invention relates to a kind of Technology with waste or used plastics manufacturing paint.

Plastics are in light weight with it, easily be shaped and cost low and be widely used in article such as making various containers and casing, still, plastics are a kind of materials that are difficult to dissolve with modification, therefore increasing waste or used plastics becomes a global problem that has a strong impact on environment.Paint is the very big decorative paint of a kind of consumption, but existing paint (as being the paint of raw material with the polyvinyl alcohol) complex manufacturing, facility investment is big, and the material cost height.

The objective of the invention is to provide a kind of novel process with plastic waste manufacturing paint, what this technology had not only solved waste or used plastics utilizes problem again, and a new way that reduces the paint cost is provided.

For achieving the above object, paint manufacturing technology of the present invention is made film forming material with polystyrene plastic or ABS plastic, makes solvent with benzene (or chloroform), make properties-correcting agent with rosin (or pitch prill), make conditioning agent with dimethylbenzene, make solvent, make optical brightener with aluminum stearate (or zinc) with gasoline (or kerosene), make tinting material preparation technology with dyestuff and comprise plastic waste clean, dissolving, add conditioning agent, modification adds tinting material, add optical brightener, and step such as filtration.

Manufacturing process required equipment of the present invention few (major equipment has stirrer, strainer, runner milling etc.), raw materials cost is low, and comprehensive cost has only the polyvinyl alcohol type to paint this 1/4-1/3.

Below in conjunction with embodiment the present invention is done detailed description.

1, prescription (by weight percentage)

Polystyrene (or ABS) plastics 30-35

Benzene (or chloroform) 25-30

Rosin (or pitch prill) 10-15

Dimethylbenzene 30-35

Oil-soluble colourant 5-8

Gasoline (or kerosene) is an amount of

Aluminum stearate (or zinc) 0.3-0.5

2, manufacturing process

The A preliminary election of at first waste or used plastics being classified is cleaned polystyrene (claiming foam again) or ABS plastic with clear water (using sanitising agent in case of necessity), and airing or oven dry.

B slowly adds clean plastics in the container that benzene is housed, and makes it whole dissolvings (be gluey, can make viscose glue and use).

C adds gasoline or kerosene in another container of dimethylbenzene is housed.

D with the product uniform mixing that obtains among step B and the C after, add rosin or pitch prill, and make it dissolving.

E adds oil-soluble colourant on step D basis, and stirs and to make it dissolving, adds aluminum stearate (or zinc) thereafter, and mixes.

F strainer pressure filtration promptly obtains qualified finished product.

If the light paint vehicle of preparation, available acrylic or methacrylic acid substitutes rosin.

Principle of the present invention also is suitable for doing with following material the system lacquer craftwork of filmogen: nylon, acrylic, synthetic glass, polyvinyl chloride, polyethylene and polypropylene.

Claims

A kind of technology with plastic waste manufacturing paint is characterized in that may further comprise the steps:

Clean polystyrene or the adding of ABS plastic 30-35 weight part are equipped with in the container of 25-30 part benzene or chloroform, make its whole dissolvings;

Getting the adding of an amount of gasoline or kerosene is equipped with in another container of 30-35 part dimethylbenzene;

Behind the solution uniform mixing in above-mentioned two containers, add 10-15 part rosin or pitch prill, add oil-soluble colourant after the dissolving again;

Add 0.3-0.5 part Zinic stearas (or aluminium) at last, pressure filtration behind the uniform mixing.
