Description
Technical Field
the invention belongs to the field of organic and inorganic composite material processing and preparation and corresponding application, and particularly relates to a high-strength, wear-resistant and corrosion-resistant composite filler particle for preparing a polyethylene corrugated pipe outer sleeve layer and a preparation method thereof, wherein the composite filler particle is prepared from biomass solid waste resources, namely shells.
background
Currently, the environment and resources are two major problems of social concern at present, and the green environmental protection concepts of energy saving, consumption reduction and the like gradually enter the daily production and life of people, and the environmental protection problems of 'water and water co-generation', 'air purification', 'garbage classification', 'green disposal and treatment of solid waste resources' and the like gradually become the research focus of the scientific researchers. In the case of the traditional plastics industry, the "white pollution" problem that occurs with traditional plastics has an immeasurable negative impact on the ecological environment, given that they are more difficult to degrade. On the other hand, as the source materials of the traditional polymer are mainly petroleum, and the petroleum is a nonrenewable resource, along with a large amount of development and complex reaction to generate a series of derivative products, the petroleum resource is gradually reduced and simultaneously generates a large amount of harmful products, which bring immeasurable harm to the natural environment on which people live, so that the environmental problems of greenhouse effect, haze and the like gradually puzzle people's life.
Because of the corrugated structure and the design of PE material, the high-density polyethylene (HDPE) corrugated pipe has strong pressure resistance, good chemical stability, low-temperature resistance, bending resistance, impact resistance and convenient construction performance, and is widely applied to municipal engineering, underground embedding and drainage and pollution discharge of residential districts, pre-buried pipelines of highways, irrigation and water delivery of farmland, drainage of waterlogging, chemical engineering, mine fluid delivery and the like. The HDPE double-wall corrugated pipe is a pipe with an outer wall with an annular structure and a smooth inner wall, and is firstly developed in Germany in the early 80 s. The production process and the use technology are mature, and the method has been greatly popularized and applied in developed countries such as Europe and America and the like due to the excellent performance and the relatively economic cost. However, at present, with the serious pollution of underground water, especially the improvement of the requirement of alkaline resistance and acid-alkali resistance of underground pipeline materials in saline-alkali land areas, the corrugated pipe is supplemented with functional filling particles as a filler in the manufacturing process of the corrugated pipe so as to improve the application performance of the end product of the corrugated pipe. Meanwhile, due to the addition of the functional filling particles with lower cost, the usage amount of the polyethylene raw material with higher value in unit volume of the corrugated pipe is greatly reduced, so that the excellent performance of the terminal product is realized, and the environmental protection and green industrial requirements of plastic reduction, plastic reduction and resource saving are realized, thereby having obvious economic and social benefits.
Shells, the substance composition of which is mainly biological calcium carbonate, mainly show calcite or aragonite or the combination form of the two. However, at present, shells, especially mother mussels for culturing pearls, are in fact dumped randomly after the pearls are collected, so that a large amount of land resources are occupied, the appearance is influenced, and meanwhile, serious negative effects are brought to the environment. At present, the national requirements for green treatment and disposal of solid waste resources are gradually upgraded, and particularly from the aspects of recycling and green utilization of shell solid waste resources, environmental protection, improvement of corrugated pipe material application performance, reduction of plastics and reduction of plastics, biomass calcium carbonate shell powder, pyrophyllite fine powder, wollastonite and the like are taken as composite fillers to perform physicochemical reinforcement on a PE carrier, and the composite materials are applied to preparation of PE corrugated pipe outer sleeves to improve the mechanical properties, chemical corrosion resistance and the like of the PE corrugated pipe outer sleeves.
