Problems solved by technology

However, because the surface of calcium carbonate powder contains a large number of hydroxyl groups with strong hydrophilicity, it is hydrophilic and oleophobic. At the same time, the surface of inorganic particles has electrostatic interaction and high surface energy. It is easy to form aggregates when it is directly applied to filling polymers. As a result, it is unevenly dispersed in the polymer matrix, and the mechanical properties of the obtained products are difficult to meet the requirements of practi...

Embodiment 1

[0023] Take by weight 100 parts of polyvinyl alcohol (PVA), 20 parts of artificial granite calcium carbonate waste residue.

[0024] First, artificial granite calcium carbonate waste slag is added to the mechanical grinding equipment, the pressure between the grinding surfaces is controlled by the screw pressurization system to 5MPa, the control speed is 30r / min, and the residence time of the material in the grinding disc is 10s each time, and the artificial granite is obtained. The calcium carbonate waste slag powder has a mesh number of 300 mesh. Add a certain amount of waste residue powder and a certain amount of water, formamide and other plasticizers to PVA in proportion, and perform mechanical mixing in a high-speed mixer, and then store it in an airtight container for one week, so that PVA can fully absorb and increase. plasticizer. Then the mixture is extruded and granulated through a twin-screw extruder. The screw temperature of the extruder is set at: 130 / 140 / 145 / 15...

Abstract

The invention discloses an artificial engineered stone waste residue filling polymer composite. The composite comprises 100 parts of a polymer base material and 0.05-80 parts of artificial engineeredstone calcium carbonate waste residues. The preparing method of the polymer composite includes the following steps of firstly, adding the artificial engineered stone calcium carbonate waste residues into a high-speed pulverizer to be superfine pulverized; secondly, mixing and stirring a polymer with the artificial engineered stone calcium carbonate waste residue powder according to a certain ratiothrough a high-speed mixer for 10-20 minutes; thirdly, extruding and granulating the mixture through a twin-screw extruder, and conducting injection molding through an injection molding machine to obtain a required product. The composite has the advantages that by enhancing the interfacial acting force between the filler and the base material, the polymer composite has excellent comprehensive performance, the production cost of the polymer composite is effectively reduced, and environmental pollution is avoided.

Description

technical field [0001] The invention relates to the technical field of polymer composite materials, in particular to a hydrogen bond composite artificial granite waste slag filled polymer composite material and a preparation method thereof. Background technique [0002] The commonly used resin-type artificial granite is made of organic resin as a binder, mixed with natural gravel, stone powder, pigments, etc. Through the marble gang saw sawing, polishing, protection and other processes, it is made into plates of various thicknesses or processed into various special-shaped decorative materials through special-shaped processing equipment. 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 resin. These waste residues are difficult to degrade and cannot be processed again. Improper treatment will cause serious environmental pollution problems. [0003] Calcium ...
