preparation example Construction

[0054] The preparation method of described PVC wood-plastic foam board comprises the following steps:

[0055] (1) Ingredients: Weigh raw materials according to the composition of PVC wood-plastic foam board;

[0056] (2) Feeding: Start the high-speed stirring pot motor, adjust the speed to 300 rpm, and then feed. The raw materials are PVC resin → thermal deformation modifier → weather resistance modifier → composite stabilizer → ACR processing aid → PVC internal lubrication Agent→PE wax→wood powder→oxidized polyethylene wax→corrosion-resistant modifier→sodium bicarbonate→azodicarbonamide AC foaming agent→calcium carbonate→PVC reclaimed materials are put into the high stirring pot in sequence;

[0057] (3) Mixing: Adjust the stirring speed of the motor of the high stirring pot to 1400~1500 rpm, and stir and mix the raw materials in the high stirring pot. When the temperature reaches 80°C, add soybean oil as a liquid additive and control the stirring for 8~12 minutes When the ...

Abstract

The invention discloses a polyvinyl chloride (PVC) wood-plastic foam board and a preparation method thereof, belonging to the field of wood-plastic materials. According to the preparation method, PVC resin is taken as a main material, PVC reclaimed materials, calcium carbonate and various additives are added into the main material, and the PVC wood-plastic foam board is prepared by the technologies such as blending, feeding, mixing, extruding, sizing cooling and cutting. All the raw materials are mixed according to a certain order based on the performance of all the additives and reaction capacities between the additives, and best processing technology parameters are selected, so that all the additives are enabled to give full play to the respective roles and play a greater role by means of cooperation; a thermal deformation improver, a weather resistance improver and a corrosion modifier are added into the formula, so that the heat distortion temperature of the prepared PVC wood-plastic foam board reaches up to 100-110 DEG C, and the PVC wood-plastic foam board is suitable for various high-temperature severe environments; the PVC wood-plastic foam board is excellent in corrosion resistance and weather fastness, and can be exposed outdoors under the ultraviolet, wet, irradiant and ozone conditions for a long time, so that the application scope of the PVC wood-plastic foam board is greatly enlarged.

Description

technical field [0001] The invention relates to the field of wood-plastic materials, in particular to a PVC wood-plastic foam board and a preparation method thereof. technical background [0002] PVC wood-plastic composite material is a new type of composite material that has been booming at home and abroad in recent years. It refers to the use of polyvinyl chloride and wood powder, rice husk, bamboo powder and other plant fibers to mix into new wood materials, which are prepared by mixing and granulating. Composite particles. After extrusion, molding, injection molding and other plastic processing techniques, the plates or profiles produced are mainly used in building materials, furniture, logistics packaging and other industries. [0003] PVC wood-plastic board can be printed on the surface, laminated, embossed, sprayed, and can also be sawed, drilled, nailed, planed, welded, glued and thermoformed like wood. , Display panels, architectural decoration, room partitions, k...
