Abstract
The present invention has the qualities such as preferable intensity, suppleness, wearability, oil resistivity, flatness and glossiness using the plastic grain of modifying waste plastic production, realizes the high unity of economic benefit, social benefit and environmental benefit.The present invention is cleaned waste plastic back is collected with cleaning agent, waste plastic is cleaned using heating and the rotation of cleaning machine, be conducive to cleaning agent sufficiently to act on spot, greasy dirt, the viscose etc. on waste plastic, cleaning effect is more preferable, and smashed waste plastic is put into freezing chamber and carries out freezing processing, Hot-blast Heating is carried out again, on the one hand it can be improved the resistance to low temperature of reworked material, to improve its mechanical property, on the other hand waste plastic is made to be easier to melt, subsequent addition modified additive is more energy efficient when being kneaded.
Description
Technical field:
The present invention relates to plastics recovery processing technique fields, and in particular to a kind of technics of reclaim of plastic waste recycling technique.
Background technique:
As plastic products consumption figure constantly increases, waste plastic is also increasing.China's waste plastic is mainly at present
Plastic film, plastic wire and knitting, foamed plastics, plastic package box, mineral water bottle, daily plastic product, polybag and agriculture
With mulch etc..These scrapped plastic products are difficult to natural decomposition, and waste of resource, can cause strong influence to environment.According to
Solution, 2011, China's waste plastics yield was about 28,000,000 tons, and 2012 are 34,130,000 tons.The storage of these waste plastics, fortune
If defeated, processing waits the processed application of waste plastic raw material and post-processing improper, will certainly welding, it is strong to endanger the common people
Health.If can be by these waste plastic product recycling and reusings again, it will be able to economize on resources, protect environment, and obtain
Biggish economic benefit.
During the recovery processing to waste plastic, spot, viscose, label can be speckled on plastics, it is difficult to remove, this is right
The modification of subsequent plastics has a significant impact, and modified plastic grain performance can be made poor.
Summary of the invention:
The technical problem to be solved by the present invention lies in overcoming the defects of the prior art, provides a kind of technics of reclaim of plastic waste again
Utilize technique.
The technical problems to be solved by the invention are realized using following technical scheme.
A kind of technics of reclaim of plastic waste recycling technique, which is characterized in that processing step is specific as follows:
(1) waste plastic of collection is put into cleaning machine, clear water is added in cleaning machine, clear water is heated to 80-100
Degree, adds cleaning agent, opens cleaning machine by cleaning machine and carries out rotation cleaning, velocity of rotation 500-700r/min, when cleaning
Between be 20-40 minutes；
(2) cleaned waste plastic is sprayed in transmission process with clear water；
(3) plastics rinsed are subjected to cold wind spin-drying, and the plastics after drying is subjected to break process, be broken into
The plastic grain of 0.5-1cm square；
(4) broken plastic grain is put into freezing chamber and carries out freezing processing, cooling time 20-50 minutes；
(5) plastic grain freezed heat is carried out with 120 hot winds to dry 10-20 minutes；
(6) plastic grain for handling step 5 well is put into high-speed mixer, and modified additive is added, is kneaded,
Melting temperature is 180-220 degree, and mixing time is 20-40 minutes；
(7) material for being kneaded step 6, which is put into be granulated in pelletizer, can be prepared by recycling modified material.
Waste plastic in the step 1, clear water, cleaning agent weight fraction ratio be 10:20:1.
The cleaning agent is made of the material of following parts by weight: 10-20 parts of modified starch, hydroxypropyl guar gum 5-10
Part, 2-6 parts of glycine, 2-4 parts of carboxymethyl cellulose, 1-3 parts of microcrystalline cellulose, 1-2 parts of sodium alkyl benzene sulfonate, sodium citrate
0.5-2 parts, 0.5-1 parts of Phenoxyethanol, 8-15 parts of dehydrated alcohol.
The cleaning agent the production method is as follows: modified starch and hydroxypropyl guar gum are mixed and heated to 60-80 degree, into
Row heat preservation grinding, and sewage ethyl alcohol is instilled during the grinding process, it is ground when instilling, after grinding 5-15 minutes, glycine is added
And carboxymethyl cellulose, continue to grind, after 5-15 minutes, microcrystalline cellulose and sodium alkyl benzene sulfonate is added, continues
Grinding after 5-15 minutes, is added sodium citrate and Phenoxyethanol, continues to grind, and after 5-10 minutes, terminates grinding, carries out
Stirring and drying processing, can be prepared by.
The modified starch is made of starch, stearic acid, palm oil modification, production method are as follows: mix starch, palm oil
