Abstract
A kind of semi-hard plastic floor is a raw material with waste polyethylene goods or waste polyethylene film, and inorganic filler and the processing aid of crossing through coupling agent treatment in addition is again through granulation, extruding, die-cut forming.Products appearance of the present invention, anti-wear performance, heat endurance, water absorbing properties all reach the standard of polyvinyl chloride semi-hard plastic floor commonly used, and cost can descend 50%～70%.
Description
The invention belongs to the comprehensive utilization and the reprocessing of reclaiming the waste and old material of polyethylene.
Again the exploitation and the comprehensive utilization of waste or used plastics goods have become current environment protection department, have reached one of major subjects of relevant industry.Waste polyethylene goods, particularly widely used waste agricultural film on agricultural always in the severe contamination farmland, destroy agriculture production environment.How to find the reasonable development of a worn-out agricultural film and utilize way, be the problem that national governments extremely are concerned about always.As: the plastics recovery technology of Belgian Advanced Recycliy Technology company invention is to be the pellet of 8mm size with the worn-out agricultural film compacting, use the high shear adiabatic extruder behind the segregating foreign objects, polyvinyl chloride, poly strand are disconnected, mix, add filler, plasticizer manufacturing timber; The company that Japan has acts as a fuel worn-out agricultural film and burns, to utilize its heat energy; The company that has decomposes worn-out agricultural film and therefrom extracts gasoline and various organic component.Also having a kind of method is that worn-out agricultural film is cleaned, pulverizes, and granulation is used then, has domesticly also made a collection of worn-out agricultural film Granulation Equipments.But owing to can not thoroughly clean up, the pellet color of producing is not attractive in appearance, poor-performing.Just be used to produce some low-grade agricultural tools at present, draw rubbish bucket etc.Have also with new polyethylene raw material that blending is used, but the scope of application is very restricted.
The objective of the invention is to be the waste polyethylene goods, especially provide a kind of new development and utilization measure-make semi-hard plastic floor with it for the waste polyethylene film article.
Semi-hard plastic floor is one of building industry interior decoration pavement commonly used, and all adopting polyvinyl chloride usually is raw material, adds an amount of inorganic filler and plasticizer, processing aid, through extruding or rolling into sheet material, punching and shaping then.
The invention is characterized in that adopting the waste polyethylene goods is the primary raw material of said semi-hard plastic floor, even can all to adopt the waste polyethylene agricultural film of recovery be raw material, the inorganic filler of adding is to give the inorganic filler of crossing through coupling agent treatment earlier.
Details are as follows for concrete manufacture method of the present invention:
1. waste polyethylene goods or the plastic sheeting for farm use that reclaims is ground into the fritter of (5～10) * (5～10) mm, washes the oven dry of clean back with water, perhaps first washing and drying is ground into fritter again.
2. with the coupling agent of inorganic filler adding 1%～10%,, in high-speed mixer, handle as metatitanic acid fat, aluminic acid lipoprotein, silicone based coupling agent.
With 100 parts through washing dried plastics small pieces, add 100～400 parts of (percetage by weight) inorganic fillers after treatment, add 2～10 parts processing aid.This auxiliary agent mainly is the lubricant of fat hydrocarbon.As paraffin, atoleine, low molecular polyethylene fat, stearic acid and stearates.Mix in high speed kneader high speed, make film fritter and inorganic filler friction, under 70～130 ℃ of temperature actions, be dispersed in the inorganic filler.
4. mixture after being mixed through the comminutor granulation, is extruded into sheet material through extruder and sheet type extrusion die again, through press polish, cooling, is die-cut into floorboard.
This kind floorboard can be made into the floor of all kinds except that the pure white floor through add various colorants when mixing.This kind floor is compared with polyvinyl chloride semi-rigid floor, and outward appearance is identical, and its main performance all can be above the standard GB 4085-83 of semi-rigid PVC flooring as wearability, hear resistance, suction size changing rate.
Use the waste polyethylene plastic sheeting for farm use to replace polyvinyl chloride to be raw material, can make cost of material descend 50%～70%.Play simultaneously twice laid again, reduced less environmental contamination.Manufacture method of the present invention is simple, for new approach has been opened up in the utilization of the waste and old agricultural polyethylene film of China.
Below be several embodiments of the present invention:
Example 1: the worn-out agricultural film fritter with cleaning oven dry, add 100 parts (percetage by weight), calcium carbonate and 2 parts of paraffin after the titanate coupling agent through 1% is handled are mediated at a high speed down at 70～130 ℃.Granulation then is extruded into sheet material, is die-cut into floorboard.This floor anti-wear performance is better.
Example 2: the method for use-case 1, add 200 parts of calcium carbonate after treatment, add 1 part of paraffin and 2 parts of stearic acid, after 70～130 ℃ high speed is mediated down, roll into sheet material through calender, be die-cut into floorboard.
Example 3: the method for use-case 1, add 200 parts of talcum powder after treatment, add 2 parts of paraffin and 1 part of stearic acid, through extruding in flakes, be processed into the floor.
Example 4: the method for use-case 1, add 300 parts of calcium carbonate after treatment, add 2 parts of paraffin and 2 parts of stearic acid, through being extruded into sheet material, then this sheet material is sticked the polyethylene film of the thick pattern out of the press of 0.2～0.5mm, after press hot pressing, cut into composite floor brick.
Claims (3)
1, a kind of semi-hard plastic floor is made up of plastic raw materials, filler and processing aid, it is characterized in that plastic raw materials is the used vinyl goods, the inorganic filler of filler for crossing through coupling agent treatment in advance.
2,, it is characterized in that the coupling agent that treatment inorganic filling material is used is as the said semi-hard plastic floor of claim 1: a. metatitanic acid fat, the b. aluminic acid lipoprotein, c. is silicone based; The coupling agent consumption is: 1%～10%.
3, a kind of manufacture method as the said semi-hard plastic floor of claim 1:
(1) to the waste and old material of polyethylene that reclaims pulverize, wash, drying;
(2) with the coupling agent of inorganic filler adding 1～10%, in high-speed mixer, give processing;
(3) to per 100 parts of waste and old material of polyethylene, add the inorganic filler of 100～400 parts of (percetage by weight) treated mistakes, add 2～10 parts of processing aids again based on lubricant, carry out high-speed mixing then, mixing temperature will be controlled at 70～130 ℃;
(4) granulation is again through squeezing, press the mode secondary operations to be shaped to semi-hard plastic floor.
