Abstract
The polyolefine grain includes superfine active heavy calcium carbonate 78-82 %, polyolefine 12-16 %, and assistant 2-10 %. It is prepared through compounding, low speed stirring, finishing, high speed stirring, mixing, pelletizing, sieving and packing. The method can be used in production of environment protecting plastic and environment protecting treatment of waste.
Description
The present invention relates to a kind of low heat value filling polyolefine grain, belong to the processing of polymer substance or the technological process field of batching.
Its prescription of common filler parent granule that domestic enterprise produces at present is generally: heavy super fine calcium carbonate+polyolefine+other auxiliary agents (polyethylene wax, Zinic stearas, titanium dioxide etc.), its proportioning is: 60～70%+20～25%+5～20%.Because in this type of prescription, polyolefine content is up to 20～25%, so angle analysis from environmental protection treatment, there is big defective in this series products, because the polyolefine content in the common polyolefine filler parent granule is higher, when making goods after the processing in a single day carry out burning disposal, will produce a large amount of obnoxious flavoures and organic residue, cause bigger pollution to environment, so refuse bag, food bag, the consumptive material that film kind disposables such as shopping bag use all requires to adopt the modified plastics manufacturing so that carry out the environmental protection burning disposal abroad at present basically.So the goods of original common filler parent granule production have been difficult to reach society to the specification of quality of polyolefine material product and the environmental protection requirement that day covers lattice completely.If reduce polyolefinic content merely, and the content of raising lime carbonate, can select and the dispersion technology of activation treatment technology, product is difficult to assurance because of the specification of heavy super fine calcium carbonate again, not do a good job in to make the physicals of product and processing characteristics to decline to a great extent, be difficult to form ordinary production.So up at present, domestic enterprise is general all to produce filler parent granule according to above-mentioned conventional formulation; Caused and continued to make the ecotope of China to be faced with serious day by day plastic pollution on the one hand, simultaneously the utmost point cannot say for sure to demonstrate,prove the quality of plastics again.
Change because the serious harm to environment for human survival that the handling problem of common plastics goods after discarded causes for real, the present invention's low heat value filling polyolefine grain of producing of filling a prescription then can solve this problem.Owing to greatly reduce polyolefinic content in the master batch, make product less generation obnoxious flavour and the organic residue when burning made, simultaneously because pearl filler has been passed through special modification processing, thereby solved preferably pearl filler in master batch the dispersion technology problem and by the physical strength problem of the end product of this products production, the scope of application of product is improved greatly, the filling raw material that can extensively produce as multiple polyolefin articles such as curtain coating, calendering, system film, injection moulding.On the other hand, the environmental protection treatment of production, use and the waste of environment-friendly type plastic material products can be fully satisfied in preparation method's of the present invention enforcement, also has nontoxic, tasteless simultaneously in raw materials for production and the production process, non-stimulated gas, nonflammable explosive, the characteristics of no harm ray, low energy expenditure.
The present invention is achieved in that providing a kind of comprises various proportionings to be respectively active heavy super fine calcium carbonate be 78%～82%, polyolefine 12%～16%.The batching of auxiliary agent 2%～10%.Here need do an explanation; common active heavy super fine calcium carbonate shared ratio in batching is the bigger the better; just because the factor that technology realizes and can't reaching more at high proportion, so active heavy super fine calcium carbonate accounts for 78%～82% and also follows process modification to realize among the present invention.Select when selecting the heavy super fine calcium carbonate and use the coupling agent with enhancement function to make activation treatment, coupling agent quantity rises to 2.2%～2.5% activating process by 1.5% and adopts twice, 20 minutes time.Auxiliary agent is selected, and selects for use molecular weight 5000～6000, fusing point greater than 118 degrees centigrade of polyethylene waxs, and fusing point is greater than 120 degrees centigrade Zinic stearas.Coupling agent with enhancement function adopts aluminic acid lipoprotein or metatitanic acid fat.The processing step that before high-speed stirring, mixing, granulation, screening, technology of the package, earlier batching is carried out stirring at low speed, arrangement, introducing stirring at low speed is intended to mix fully, shear, the arrangement process is mainly checked the state of stirring, remove moisture content, and resistates in the equipment cleared up, adjust.
The present invention will be described with specific embodiment below.
Embodiment:
Composition of raw materials: heavy super fine calcium carbonate 80%, specification: ultra tiny and through the coupling agent activation treatment; Polyolefine 14%, specification: film enhancement type; Polyethylene wax 3%, specification: high melting point (greater than 118 degrees centigrade); Titanium dioxide 1%, specification: R type (rutile-type); Zinic stearas 2%, specification: high melting point (greater than 125 degrees centigrade).
The technological process of production:
Batching
Stirring at low speed
Arrangement
High-speed stirring
Mixing
Granulation
Screening
Packing
Wherein stirring at low speed is 10 minutes, 100 rev/mins of rotating speeds, high-speed stirring 10 minutes, 900 rev/mins of rotating speeds.
The product of explained hereafter thus, film with 0.02mm thickness is a determination object, and the PE film that low heat value filling polyolefine grain is made is as follows with the overall target contrast of Japan, Taiwan like product: film place of production tensile strength elongation at break angle tear strength falls to marking shock strength 120G
