Abstract
The invention discloses a new method for increasing the color evenness of polyvinyl chloride shaping articles, comprising: (1) respectively sorting, crashing, cleaning, drying the waste plastics; (2)pulverizing the dried crashed material by ball mill; (3) fading the pulverized material; (4) pretreatment before modifying; (5) molecule modifying; (6) graining, shaping, cutting, packaging the modified polyvinyl chloride powder to obtain finished product. The said invention does not generate any industrial pollution during the whole waste plastics recycling and the color of the finished product is even.
Description
One, technical field:
The present invention relates to key technology and the method for utilizing waste or used plastics to produce high-quality plastic material, particularly relating to the waste or used plastics is the new method that raw material improves polyvinyl chloride sectional materials combinations color and lustre evenness.
Two, background technology:
Waste or used plastics is the discarded object that life or production process produce, and it pollutes and more and more causes the concern of countries in the world.According to statistics, in the industrially developed country city was useless admittedly, waste plastics accounted for 4～20% of its weight, accounts for 10～20% of its volume.And in China, the general-purpose plastics that accounts for total amount 70～80% in the present plastics of producing will be converted into waste plastics in 10 years, wherein have nearly half plastics will be converted into waste plastics in two years.The annual callable plastics of China are more than millions of tons, and China's technics of reclaim of plastic waste rate is lower in the world, only is about 15%; The rate of recovery of developed country's waste or used plastics is all about 50%.As seen following China pollutes at the control waste or used plastics, how waste plastics is realized minimizing and resource aspect, will bear huge pressure.
The approach and the technology of traditional waste or used plastics comprehensive utilization mainly contain: burn thermal decomposition preparing liquid fuel and chemicals and directly utilization.Burning is the main path of waste or used plastics resource, by burning the accumulating amount that can reduce plastics significantly, approximately can remove 90～95% of its volume, and the combustion heat of waste or used plastics generally all is higher than timber, its energy recovery has much potentiality, and shortcoming is can produce atmosphere pollution after all types of plastic burning; Thermal decomposition preparing liquid fuel and chemicals are that primary resin high polymer in the waste or used plastics goods is carried out macromolecular chain decomposition more completely, generate the wide hydro carbons of boiling spread.But pyrolysis technique must at high temperature react, and equipment investment is bigger, the cost recovery height, and coking phenomenon is arranged in course of reaction, therefore application is restricted; Directly utilize be waste or used plastics through preliminary treatment such as pulverizing, cleanings after, carry out fusion, extrusion molding or be a granulated into new plastic products and the plastic processing raw material, shortcoming is can direct applied scope very limited.Therefore, develop the new technology that cost is low, the waste plastic regeneration of high efficiency utilizes, will become the key that plastic industry is realized sustainable development.The main feature of waste or used plastics is to have difficult combustion, resist chemical, wear-resisting, excellent electric insulation performance and higher mechanical strength etc.Shortcoming is that heat endurance is relatively poor, is heated easily to cause in various degree cracking, and the fraud that soft goods also has plasticizer to move outside, strain sensitive can not be restored after the distortion fully, and hardening at low temperatures.
Three, summary of the invention:
The object of the present invention is to provide a kind of whole technics of reclaim of plastic waste to utilize and do not produce any industrial pollution in the process, improve the new method of polyvinyl chloride sectional materials combinations color and lustre evenness.
The technical solution adopted in the present invention is: a kind of new method that improves polyvinyl chloride sectional materials combinations color and lustre evenness includes following steps: the sorting respectively of (1) waste plastics, fragmentation, cleaning, dry treatment step;
(2) dried broken material carries out abrasive dust through ball mill, and particle diameter is as the criterion about with 200nm;
(3) the abrasive dust material is sent to the pond of fading, adding bleaching powder, watery hydrochloric acid fade to powder;
(4) powder that comes out from the pond of fading is sent into and is done preliminary treatment before the modification the magnetic stirring apparatus;
(5) molecule modification: pretreated powder arrives height through pipeline transportation and stirs mixer, adds the modified additive coumarin derivative, keeps 120 ℃ of temperature 10 minutes, delivers to cooling mixing machine again, is cooled to 40～60 ℃;
(6) the polyvinyl chloride powder particle passes through granulation, moulding, cutting, packing again after the modification, obtains goods.
The present invention utilizes in whole technics of reclaim of plastic waste and does not produce any industrial pollution in the process, and the product color of production is even.
Four, description of drawings:
Fig. 1 is a process chart of the present invention.
Five, the specific embodiment:
The present invention is further described below in conjunction with the drawings and specific embodiments:
Embodiment: the present invention is a raw material with wide material sources, waste plastics with low cost, and the step of its technology is as follows:
(1) adopts artificial separation, remove tentatively that institute mixes matter in the waste plastics heap;
(2) waste plastics of sorting is expected that by white material, ash different stockpiles is with the hammer crushing crusher machine respectively;
(3) fragmentation is after trolley is transported to the waste plastics cleaning equipment---and self-loopa is filtered supersonic wave cleaning machine and is cleaned, and cleans after belt transports, and with 30 ℃ hot-air blower drying, it is sign that degree of drying is measured its sample moisture content≤0.5% with the karl Fischer Moisture Meter;
(4) clean and dried broken material is transported to milling plant through transport tape, carry out abrasive dust with ball mill, and with its mill back fineness of particle size analyzer determination, particle diameter is as the criterion about with 200nm;
(5) go out the abrasive dust material and be transported to the pond of fading of chemical workshop, add medicaments such as bleaching powder, watery hydrochloric acid powder is faded through belt;
(6) powder that comes out from the pond of fading is sent into the magnetic stirring apparatus, and powder is done preliminary treatment before the modification;
(7) molecule modification: pretreated powder arrives height through pipeline transportation and stirs mixer, adds the modified additive coumarin derivative, keeps 120 ℃ of temperature 10 minutes, delivers to cooling mixing machine again, is cooled to 40～60 ℃;
(8) the polyvinyl chloride powder particle enters comminutor through discharge pipe after the modification, adds colouring agent and processing aid, kneading, homogenizing, granulation;
(9) homogenizing and granulating enters extruder plastication and extrusion molding after transmission channel is delivered to the feeding machine of assembly room by barrel;
(10) section bar of moulding depanning obtains surface-brightening, the uniform high-quality polyvinyl chloride-type material products of color and luster by hauling machine traction, cutting, packing.
