Abstract

The invention discloses a recovery technique of waste plastic, which comprises the following steps: classifying and cleaning recovered plastic to remove impurities on the plastic; cutting the cleaned plastic into plastic granules by a cutting machine, and evenly mixing the plastic granules, heat stabilizer and assistant in a mass ratio of 5:1:2; putting the mixture into an injection molding machine, heating to 180-220 DEG C, and keeping the temperature for 30-45 minutes; and finally, carrying out injection molding or extrusion molding to obtain the finished product. The technique disclosed by the invention is simple and low in cost; and the plastic product recovered by the technique has the advantages of long service life and wide application range, and has strong market competitiveness.

Description

A kind of recovery process of waste or used plastics

Technical field

The present invention relates to field of plastic products, specifically, specially refer to a kind of recovery process of waste or used plastics.

Background technology

Plastics are synthetic macromolecular compound { polymkeric substance (polymer) }, can be described as again polymer or giant molecule (macromolecules), be also plastics (plastics) or the resin (resin) that generally is commonly called as, can freely change the body pattern.Be the material that utilizes raw material monomer to be polymerized with synthetic or condensation reaction, formed by additives such as synthetic resins and filler, softening agent, stablizer, lubricant, colorants.

The main component of plastics is synthetic resins.This noun of resin is to be gained the name by the oozy lipid of animals and plants at first, and as rosin, shellac etc., resin refers to not yet the superpolymer that mixes with various additives.Resin accounts for 40%~100% of plastics gross weight.The fundamental property of plastics depends mainly on the person's character of resin, but additive also plays an important role.Some plastics is comprised of synthetic resins basically, does not contain or contain less additive, as organic glass, polystyrene etc.

Application number is that 91106055.3 patent application document discloses a kind of waste plastic regeneration technique, at first waste or used plastics is carried out conventional processing, then skeleton is carried out cooling and shaping, then applies new plastic on the skeleton surface.The defective of this technique is and can't upgrades the inside of recycled plastic, and the work-ing life of plastics that causes reclaiming replacement is shorter.

In sum, for the defective of prior art, need especially a kind of recovery process of waste or used plastics, to solve the deficiencies in the prior art.

Summary of the invention

The object of the present invention is to provide a kind of recovery process of waste or used plastics, by traditional plastics recovery technique is improved, the long service life of the plastics that reclaim by this technique, applied widely, possesses the stronger market competitiveness, thereby overcome the deficiency in the conventional art, realized purpose of the present invention.

Technical problem solved by the invention can realize by the following technical solutions:

A kind of recovery process of waste or used plastics, it comprises the steps:

1) at first with the plastics classification of reclaiming, clean, remove on plastics with impurity;

The plastics that 2) will clean after complete cut into granular plastic grain by cutting machine, then plastic grain, thermo-stabilizer and auxiliary agent three are evenly mixed by the mass ratio of 5:1:2:

3) with step 2) in mixture put into injection moulding machine, then be heated to 180-220 degree centigrade and kept 30-45 minute;

4) obtain finished product by injection moulding or extrusion moulding at last.

In one embodiment of the invention, described plastic grain is spherical or Polygons.

In one embodiment of the invention, the minimum outer diameter of described plastic grain is less than 0.6 centimetre.

Beneficial effect of the present invention is: technique is simple, and is with low cost, and the long service life of the plastics that reclaim by this technique is applied widely, possesses the stronger market competitiveness.

Embodiment

For technique means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with embodiment, further set forth the present invention.

The recovery process of a kind of waste or used plastics of the present invention, it comprises the steps:

1) at first with the plastics classification of reclaiming, clean, remove on plastics with impurity;

The plastics that 2) will clean after complete cut into granular plastic grain by cutting machine, then plastic grain, thermo-stabilizer and auxiliary agent three are evenly mixed by the mass ratio of 5:1:2:

3) with step 2) in mixture put into injection moulding machine, then be heated to 180-220 degree centigrade and kept 30-45 minute;

4) obtain finished product by injection moulding or extrusion moulding at last.

It is pointed out that described plastic grain is spherical or Polygons, design by said structure, facilitated next step processing.

It should be noted that the minimum outer diameter of described plastic grain is less than 0.6 centimetre.

The present invention is by improveing traditional plastics recovery technique, and the long service life of the plastics that reclaim by this technique is applied widely, possesses the stronger market competitiveness, thereby has overcome the deficiency in the conventional art, realizes purpose of the present invention.

Above demonstration and described ultimate principle of the present invention and principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and specification sheets just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
