specific Embodiment 1

[0021] The PVC resin plasticizer is a graft, prepared from the following raw material components according to the weight percentage of each component: high-density oxidized polyethylene wax (OPEW) 30%, initiator (BPO) 1.2% , maleic anhydride (MAH) 14%, ethylene-vinyl acetate (EVA) 9.8%, activated calcium carbonate 45%.

[0022] Described PVC resin plasticizer can be prepared by following method:

[0023] Step 1, according to the raw material components and corresponding proportions of the PVC resin plasticizer, take each raw material component for subsequent use;

[0024] Step 2. Put the raw materials weighed in step 1 into a stirring mixer, and mix them at a temperature of 105-125 °C until they are evenly mixed;

[0025] Step 3. Put the uniformly mixed materials into the extruder, and carry out extrusion and pelletizing operations under the conditions of temperature 80-120°C and rotation speed 30-60 rpm to make graft filler particles.

[0026] The production raw material co...

Abstract

A PVC (polyvinyl chloride) resin plasticization promoter is prepared from the following raw materials in percentage by weight: 20-45% of high density oxidized polyethlene wax (OPEW), 0.5-5% of an initiator (BPO), 10-25% of maleic anhydride (MAH), 1-12% of ethylene-vinyl acetate (EVA) and 30-45% of activated calcium carbonate. The PVC resin plasticization promoter is a graft, is nontoxic and harmless, has an excellent PVC resin plastification characteristic, is applied to production of the PVC wood-plastic decoration material, replaces a plasticizer, and can avoid harms and threat caused by the plasticizer to human and an environment in the prior art basically, improve the plastification processability of type 4 and 5 PVC resin and the product quality of the PVC wood-plastic decoration material, and achieve ecologicalization, harmlessness and high strength of a product; at the same time, the production cost of the product can also be lowered greatly.

Description

technical field [0001] The present invention relates to a resin plasticizer and its preparation and application, in particular to a PVC resin plasticizer and its preparation method, and a process of using the PVC resin plasticizer to manufacture PVC resin wood-plastic decorative materials method. Background technique [0002] PVC resin wood-plastic material is a foamed composite material that has both the advantages of wood and plastic. It has high impact resistance and ductility, and has been widely used in the fields of interior decoration and packaging materials. In the current production, PVC resin wood-plastic decoration materials are mostly produced with 7 and 8 types of PVC resin. The melt strength of 7 and 8 types of PVC resin is insufficient, and the viscosity is too low. Bubbles and string bubbles lead to difficulties in material molding and processing, resulting in low product strength, poor toughness, and brittle materials. [0003] Type 4 and Type 5 PVC resins...
