Problems solved by technology

Although this method is simple and highly operable, there is no indication whether it is equally applicable to the five general-purpose plastics of polyethylene, polypropylene, polyvinyl chloride, polystyrene and ABS.
In addition, since this method does not discuss the interface characteristics of artificial granite waste slag and matrix resin, how to further improve the compatibility between the two, and then obtain a polymer composite material with better comprehensive performance, it shows that in this method There is still room for improvement on the basis of

Abstract

The invention discloses reinforced and antibacterial plastic masterbatch based on artificial agglomerated stone waste residues and a preparation method thereof. The masterbatch comprises the followingcomponents in parts by mass: 100 parts of resin, 400-900 parts of an artificial agglomerated stone waste residue-inorganic powder compound, 5-200 parts of a reinforcing agent, 0.2-15 parts of a surface modifier, 0.1-5 parts of a chain extender, 0.2-4 parts of a compatibilizer, 1-25 parts of an antibacterial agent, 0.3-2 parts of a lubricant and 0.5-2.5 parts of an antistatic agent. According to the invention, the artificial agglomerated stone waste residue-inorganic powder compound is used as a filler to prepare the plastic masterbatch; the mutual characteristics of the artificial agglomerated stone waste residues and the inorganic powder can be used make the best of the both materials, defects in performance when only artificial agglomerated stone waste residues are adopted as a fillingcomponent are eliminated, and a plastic masterbatch product with ideal comprehensive performance is obtained. The preparation method has the advantages of simple process, good economical efficiency, suitability for large-scale production, reduction of the pollution of solid wastes to the environment, and realization of the resource recycling of wastes.

Description

technical field [0001] The invention relates to the technical field of environmental protection and reuse of construction waste, in particular to an enhanced and antibacterial artificial granite waste slag-based plastic masterbatch and a preparation method thereof. Background technique [0002] Plastic filler masterbatch is made by mixing and kneading various additives, fillers and a small amount of carrier resin for the convenience of operation during the plastic processing and molding process. Plastic filled masterbatches mainly use inorganic powder as the basic material, add carrier resin and various modification additives to obtain high-filling masterbatches that can meet the requirements of plastic product molding processes through extrusion and granulation. The primary purpose of plastic filling masterbatch is to reduce the production cost. Most of them use cheap and widely sourced inorganic powder or industrial waste as filling materials. At present, the basic materia...
