Abstract
The PE-flyash composition for producing high rigidity large caliber pipe consists of PE material 100 weight portions, reinforced flyash material 40-65 weight portions and through common mixing process. The reinforced flyash material is prepared through mixing 200-500 mesh flyash 100 portions, PE coupling agent 1-8 portions and lubricant 2-3 portions via high speed stirring at 90-95 deg.c for 3-5 min; adding PE material 5-30 portions via high speed stirring at 100-120 deg.c for 5-10 min; and extrusion to pelletize at 140-180 deg.c in a special screw extruder. The said process makes the PE-flyash composition capable of being used in producing high rigidity large caliber pipe.
Description
Technical field
The present invention relates to the PE fly ash composition, particularly relate to the PE fly ash composition that can be used for manufacturing high rigidity heavy caliber pipe.
Background technology
Flyash is industrial residue, and its main component is SiO
2, AI
2O
3, belonging to manosil AS class inorganic powder material, its outward appearance is free-pouring transparent or semitransparent hollow amorphous glass spheroid.Cenosphere has light weight, low heat conduction, nontoxic, fire-retardant, advantages such as chemical stability is good, high dispersive, can improve and improve water tolerance, compressive strength, shrinking percentage and the shock strength of PE resin; Because good fluidity, work in-process can reduce the wearing and tearing to equipment, makes that corrosion-resistant, wear-resisting, the anti-width of cloth of composite pipe is penetrated, heat insulating; More, the mechanical property of composite pipe is improved because stress concentration power is little.Therefore, be that the various high value added products of development of raw materials are one of some industries, area research and hot of research and development with flyash.At plastic industry, the patent No. is 00132516.7 patent, the extruding of waste or used plastics and flyash composite product, injection method for producing are provided, and manufacturing tubing in the aforesaid method and be with waste or used plastics, flyash, the different proportionings of chemical assistant is that main ingredient directly makes tubing.Select for use on the waste or used plastics component from it, because the polymer of plastics degraded, molecular weight reduces, and its shortcoming is that the product rigidity that makes is descended, and fragility increases, limited the production of heavy caliber pipe, the shrinking percentage of heating once more is excessive, though there is flyash to add the waste or used plastics mechanical property is increased, and is difficult to eliminate the internal stress in the tube forming, pipe outer surface is subsided, the internal surface pit; From flyash content, about 10% (weight percent) of the total component of flyash ingredients constitute, its shortcoming is that the flyash add-on is few, does not eliminate the plastics internal stress, can not guarantee raising of tubing rigidity and elimination tubing surfaces externally and internally pit, subside, can not guarantee that the tubing surfaces externally and internally is smooth; On manufacture method, components such as waste or used plastics and flyash directly are extruded into tubing, its shortcoming is to guarantee the polymolecularity of flyash in plastics, influences the isotropy of tubing, does not also guarantee the tubing visual appearance.The tubing that adopts above-mentioned patent scheme to make, the outward appearance of tubing and mechanical performance index do not reach country and industry standard, are difficult in the engineering and use.Therefore, though can make tubing, use value is lower.
Summary of the invention
Technical problem to be solved by this invention is, its component that existing waste or used plastics and flyash composite pipe exist adopts waste or used plastics, and the flyash component concentration is few, directly be extruded into tubing and can not guarantee the polymolecularity of flyash in plastics, and the product rigidity that causes making descends, fragility increases, stress concentration, form the surfaces externally and internally unfairness of tubing, influence the isotropy of tubing, limited the deficiency of producing heavy caliber pipe.
For solving the problems of the technologies described above, the invention provides a kind of PE fly ash composition that can be used for manufacturing high rigidity heavy caliber pipe, it is by 100 parts of PE raw materials, and flyash strengthens masterbatch 40--65 part, and the general method uniform mixing is formed.Wherein flyash enhancing masterbatch is made by following method: a) get 100 parts in 200--500 purpose flyash, PE uses coupling agent 1--8 part, and lubricant 2--3 part was at 90--95 ℃ of following high-speed stirring 3--5 minute; B) add PE raw material 5--30 part again, at 100--120 ℃ of following high-speed stirring 5--10 minute; C) enter in the bolt special forcing machine, at 140--180 ℃ of following extruding pelletization.Above-mentioned all umbers are parts by weight.
The invention of this composition is on the one hand because the component of plastics is the PE raw material, and PE does not degrade, and molecular weight is more than 1.5--2 a times of waste or used plastics, and the tubing rigidity that makes is improved, and stress concentration power is little; Because the amount of flyash accounts for the 24--34% (weight percent) of total component, and the flyash add-on is more, has eliminated the plastics internal stress, also be the factor that improves tubing rigidity on the other hand; Flyash is to adopt flyash enhancing masterbatch component mode to add to make tubing in addition, has guaranteed the polymolecularity of flyash in PE, has guaranteed the isotropy of tubing.Compared with the prior art, adopt composition provided by the invention, its beneficial effect is to manufacture high rigidity (the ratio of rigidity prior art improves 30--50%) the smooth tubing of heavy caliber surfaces externally and internally, improved tubing fragility, the dimensional stability of tubing improves, shrinking percentage reduces more than 40%, and the cost 20--30% that can descend has dwindled the ratio price differential with the conventional tube material.
