Embodiment 1

[0032] (1) Preparation of AM mixture:

[0033] Synthesis of acrylate monomer emulsion: add 6g sodium lauryl sulfate, 3g potassium persulfate, 100g deionized water into the reaction kettle, stir and pass nitrogen, add 225.6g methyl methacrylate, 56.4 g butyl acrylate with Na 2 SO 4 The pH value of the emulsion is adjusted by the solution to 8, and the temperature is kept at 50° C. for 2 hours, and the temperature is lowered to obtain an acrylate monomer emulsion;

[0034]Preparation of AM mixture: Add 200 g of deionized water, 12 g of sodium lauryl sulfate, 12 g of potassium persulfate and 818 g of acrylate monomer emulsion prepared in the previous step into a stainless steel autoclave, containing 282 g of acrylate monomer, Use 5% to 10% NaOH solution to adjust the pH value of the mixed reaction solution in the range of 9 to 11, then add 18g of crosslinking agent DCP and silane coupling agent KH-560, fill with nitrogen, vacuumize and exhaust oxygen, repeat 3 times, then add ...

Abstract

The invention belongs to the field of chemical synthesis and specifically relates to an AM mixture used for wood plastic products and preparation and application methods thereof. The AM mixture is characterized in that the mixture is an acrylic polymer which uses chlorinated polyethylene as main elastomers and a coupling agent and a cross-linking agent as compatilizers and is prepared with the aid of polymerization and grafting of acrylic acid ester monomers. The AM mixture provided in the invention can effectively improve impact strength and tensile strength of a wood plastic product, provides the wood plastic product with certain processing performance, can effectively enhance compatibility among wood powder, calcium powder and PVC and dispersibility of the powders and enables weatherability of the wood plastic product to be well performed.

Description

technical field [0001] The invention belongs to the field of chemical synthesis, and in particular relates to an AM mixture applied to wood-plastic products and its preparation and application methods. Background technique [0002] Wood-plastic composites (Wood-Plastic Composites, WPC) is a new type of composite material that has been booming at home and abroad in recent years. It refers to the use of polyethylene, polypropylene and polyvinyl chloride, etc. More than 70% of wood flour, rice husk, straw and other waste plant fibers are mixed into new wood materials, and then processed by extrusion, molding, injection molding and other plastic processing techniques to produce boards or profiles. Mainly used in building materials, furniture, logistics packaging and other industries. The board formed by hot extrusion after mixing plastic and wood powder in a certain proportion is called extruded wood-plastic composite board. As a new type of wood substitute material, wood-plas...
