Cellulose hybrid filler reinforced polymer composite material and preparation method thereof

Abstract

The invention discloses a cellulose hybrid filler reinforced polymer composite material and a preparation method thereof. The material comprises the following raw materials: 100 parts of polymer matrix; 5 parts of compatilizers; and 1-40 parts of engineered stone waste / agricultural and forestry waste hybrid fillers. The preparation method includes the following steps: (1) blending the engineered stone waste and the agricultural and forestry waste, and adding water to prepare an aqueous dispersion; (2) grinding the aqueous dispersion to prepare a micro-nano hybrid filler dispersion; (3) performing suction filtration on the micro-nano hybrid filler solution, drying, and mechanically crushing to obtain micro-nano hybrid filler powder; (4) blending the micro-nano hybrid filler powder with thepolymer and the compatilizers, and stirring; and (5) extruding and granulating the mixture through a machine, and performing injection molding through an injection molding machine to obtain a corresponding product. The method has the advantages of reasonably and effectively realizing high-value utilization, avoiding environmental pollution, effectively solving the problem that cellulose is easy toagglomerate in non-polar polymer, and endowing polymer composite materials with excellent mechanical properties.

Description

technical field [0001] The invention relates to the technical field of polymer composite materials, in particular to an artificial granite calcium carbonate waste residue / agricultural and forestry waste hybrid filler-reinforced polymer composite material and a preparation method thereof. Background technique [0002] Artificial granite is made of polymer, inorganic gelling agent or a mixture of the two as the binding material, with natural stone scraps, aluminum hydroxide powder, etc. Processed stone. Resin-based artificial granite is an artificial stone made of marble, limestone and other crushed and powdered materials as the main raw materials, and resin as the binding material. During the processing of artificial granite, a large amount of waste residue will be produced. The main components of waste residue are calcium carbonate and unsaturated polyester. These waste residues are difficult to degrade and cannot be reprocessed. Improper treatment will pollute the environm...

Problems solved by technology

At present, solvent replacement, addition of surfactants, in-situ polymerization, or direct surface modification of cellulose are mostly used to improve the interfacial interaction between cellulose and polymer matrix, but the improvement effect is often not ideal, and the use of organic solvents, not only It will cause environmental pollution and increase the cost, making it difficult to use in actual production
