Abstract

The present invention provides lightweight opal shale functional plastic particles and a production method therefor. The method is characterized in that: the functional plastic particles made from lightweight opal shale powder and plastic particles and an assistant have relatively strong hygroscopicity, adsorption, antibacterial performance, and combustion-supporting performance; have functions such as anti-mildew, odor removal, and the like; and also have mechanical properties of enhancement, toughening, tensile strength improvement, elongation at break, and the like; products made from the particles provided by the invention are light in weight, and smooth, the shrinkage is reduced, and the heat distortion temperature is improved; and the functional plastic particles have features such as care functions, affordable raw materials, and low prices.

Description

A kind of light-weighted opal shale functional plastics particle and making method

Background technology

The present invention relates to a kind of functional plastics particle manufacturing technology field, particularly relate to a kind of light-weighted opal shale functional plastics particle and making method.

Technical field

Functional plastics particle, be exactly by plastic pellet modification in addition, the resins for universal use in enormous quantities namely petrochemical enterprise produced, by the method for the machinery of the chemistry of physics, improve or increase its function, the plastic functional particle used reach special environment condition in magnetic, optical, electrical, ageing-resistant, fire-retardant, mechanical property etc. under; Its method: carrying out modification by adding coupling agent, inorganic mineral coarse whiting, talcum, mica, barium sulfate, tripoli, glass microballon, polynite etc. in resin, reaching required functional particles; This particle Shortcomings part, made product proportion comparatively large, same volume product is heavier; Particularly relate to a kind of light-weighted opal shale functional plastics particle with nourishing function, also should at present and do not find application and record.

Summary of the invention

For the deficiencies in the prior art, the invention provides a kind of light-weighted opal shale functional plastics particle and manufacture method thereof, it is the functional plastics particle be processed into light-weighted opal shale powder and plastic pellet and auxiliary agent, the function such as this particle has stronger water absorbability, adsorptivity, germ resistance, combustion-supporting property, it is anti-mildew to have, eliminate the unusual smell, can also strengthen simultaneously, toughness reinforcing, improve the mechanical property such as tensile strength and elongation at break; Make product weight with it light, smooth, reduce contraction, improve heat-drawn wire; Have nourishing function, raw material is easily purchased, lower-price characteristic; In order to achieve the above object, the technical solution used in the present invention is as follows:

A kind of light-weighted opal shale functional plastics particle is processed by plastic pellet, light-weighted opal shale powder and auxiliary agent;

Making method (by weight part): get plastic pellet 40-80 part, adopt freezing method that described plastic pellet is pulverized 60-100 order powder, then dry, water content control is less than 0.03%, then adds coupling agent 5-10 part, dispersion agent 10-20 part; It all put together, fully stirs, put into twin screw extruder, melt extrude, cool, pelletizing, make light-weighted opal shale functional plastics particle;

Described plastic pellet is: polyethylene, polypropylene, polychlorostyrene second, the one wherein such as polystyrene;

Described opal shale diameter of particle is 0.5-1 micron.The people such as opal shale has another name called opoka, rotten-stone, is a kind of rare ore, nineteen eighty-three Peking University professor Ren Leifu find, the opal light shale be made up of cristobalite, phosphorus quartz, opal is a kind of rare ore.Its chemical composition: SIO284.25%, AI2034.79%, FeO20.12%, MgO20.29%, CaO20.57%, Na2O0.12%, K2O0.54%, H2O0.10%, TiO20.20%, P2O50.26%, MnO0.01%, Gr do not detect, Hg (0.00001%; Physicals: outward appearance is in white, grey, quality is fine and smooth, it is large especially that ore has a large amount of poriform microporosity specific surface areas, 277.3cm2/g can be reached, water-intake rate 73.4%, aperture 5-20n. porosity is high, and water-absorbent is strong, adsorptivity is very strong, has emitting far-infrared and negative aeroion function containing a large amount of metal oxides; According to the physicochemical property of opal shale, be applied in macromolecular material, be processed into new function particle, the function such as this particle has stronger water absorbability, adsorptivity, germ resistance, combustion-supporting property, it is anti-mildew to have, eliminate the unusual smell, can also strengthen simultaneously, toughness reinforcing, improve the mechanical property such as tensile strength and elongation at break;

Described coupling agent is silane coupling agent, titanate coupling agent, any one in aluminate coupling agent.

Described dispersion agent is any one in PE macromolecule wax, PP molecular wax, EVA.

The present invention compared with prior art has the following advantages:

(1) manufacture craft is unique, freezing plastic pellet is pulverized and adds light-weighted opal shale powder and auxiliary agent is all put together, material is powdery, be conducive to abundant stirring, various material is made fully to contact closely, homogeneous more after heating, improve product physicochemical property you, functional materials is played more perfect;

(2) opal shale functional fibre of the present invention can launch wavelength absorbed by the body at the far infrared rays of 4 ~ 14 microns, produce idling ion, anion emission rate can reach 700/cubic centimetre, these functions superpose mutually, have stronger water absorbability, adsorptivity, germ resistance, combustion-supporting property, anti-mildew, eliminate the unusual smell, there is enhancement function effect, microcirculation in human body can be promoted, enhance metabolism, strengthen body immunity.

(3) this functional particles is used for plastics, agricultural, chemical preparations, cosmetics of everyday use, is particularly applied to the application etc. in modifying plastics field.

Embodiment

Below in conjunction with embodiment, the present invention is described further: described light-weighted opal shale functional plastics particle is processed by light-weighted opal shale powder and plastic pellet and auxiliary agent, and embodiment is as follows:
