Problems solved by technology

In recent years, spirulina farming enterprises will treat the leftovers as waste products. For example, the sediments at the bottom of the breeding pond and the substandard materials in each link of production are finally disposed of as waste materials, which has caused serious pollution to the environment.

Abstract

The invention discloses a preparation method for a novel HDPE composite material. The preparation method comprises the following steps: (1) crushing leftover spirulina to a size of 50 meshes, adding a pretreatment fluid, adjusting water content to 50%, maintaining temperature to be 90 to 110 DEG C carrying out soaking for 50 to 82 min, and after completion of soaking, carrying out heating at 150 DEG C for 3 to 5 min; (2) crushing corn straw to a size of 60 meshes, adjusting water content to 50% with water, inoculating the crushed corn straw with Lactobacillus plantarum, carrying out fermentation at 38 DEG C for 30 min and after completion of fermentation, carrying out heating at 70 DEG C for 10 min; (3) uniformly mixing the spirulina powder and the corn straw powder, putting the obtained mixture into a continuous steam explosion machine for steam explosion three times; (4) drying a material obtained after steam explosion at 100 DEG C and crushing the material to a size of 80 meshes after drying; and (5) mixing a mixture obtained in the previous step, HDPE and a coupling agent according to a mass ratio of 1.2: 1: 0.05 and then carrying out molding so as to obtain a sheet material.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a novel HDPE composite material. Background technique [0002] High Density Polyethylene (HDPE for short), also known as low-pressure polyethylene, is a highly crystalline, non-polar thermoplastic resin. The appearance of the original HDPE is milky white, and the thin section is translucent to a certain extent. PE has excellent resistance to most domestic and industrial chemicals. HDPE is a highly crystalline, non-polar thermoplastic resin. High-density polyethylene is a white powder granular product, non-toxic, tasteless, density in the range of 0.940-0.976 g / cm3; crystallinity of 80%-90%, softening point of 125-135°C, and service temperature up to 100 ℃; the melting temperature is 120~160℃. For materials with larger molecules, the recommended melting temperature range is between 200~250℃. It has good heat resistance and cold resistance, good chemical s...
