Embodiment Construction

[0043] The present invention will be further described below in conjunction with specific examples, so that those skilled in the art can better understand the present invention and implement it, but the given examples are not intended to limit the present invention.

[0044] (1) Take some crushed 80-mesh wood chips and put them into a dryer for drying. The drying temperature is 115°C-120°C, and the drying time is 2 hours;

[0045] (2) Accurately weigh the raw materials in Table 1, put them into a high-speed mixer after mixing, and wait for the self-friction heat to reach 106°C, and then naturally drop to room temperature;

[0046] (3) Start the twin-screw extruder, and set four temperature zones between the feed port, the barrel and the outlet die, which are respectively 166°C in the first barrel zone, 169°C in the second barrel zone, and 171°C in the third barrel zone. ℃, machine head 174 ℃, after the standby body rises to the set temperature, put in the mixed raw materials i...

Abstract

The invention discloses an inorganic mineral filled wood-plastic composite material and a preparation method thereof. The composite material is prepared from the following raw materials in parts by weight: 5-50 parts of organic macromolecule resin, 1-100 parts of inorganic mineral material, 2.5-30.0 parts of wood raw material, 0-5 parts of plasticizing agent, 0.25-5.00 parts of coupling agent, 0.05-2.00 parts of foaming agent, 0.01-3.00 parts of foam control agent, 0.05-4.00 parts of impact modifier, 0.05-4.00 parts of lubricating agent, and 0.1-5.0 parts of stabilizing agent. The preparation method comprises the following steps of: crushing and drying all the raw materials, mixing the crushed materials, and extruding the mixture by an extruder to obtain the inorganic mineral filled wood-plastic composite material. According to the composite material, the inorganic mineral material is used as a filling agent, one the one hand, special functional characteristics of the inorganic mineral material are reflected, on the other hand, mechanical property and processability of a material in the original prescription are maintained, investment on the wood material and the other materials with pretty high cost is reduced, and the cost of the wood-plastic composite material is greatly reduced.

Description

technical field [0001] The invention relates to the field of wood-plastic composite materials, in particular to an inorganic mineral-filled wood-plastic composite material composed of organic polymer resin, wood raw materials and inorganic mineral materials and a preparation method thereof. Background technique [0002] Wood-polymer Composites (WPC for short) is based on wood chips and other primary biomass materials, mixed with a certain proportion of plastic base materials, using the chemical principle of polymer interface and the characteristics of plastic filling modification, through special A new type of environmentally friendly material that is processed and formed after technological treatment. The material combines the advantages of wood and plastic, has excellent mechanical properties and processing properties, and has the ability to overcome the shortcomings of wood such as moth-eaten, moisture absorption, and deformation. Compared with wood, this material is lig...
