Introduction to WPC Embossing Board materials

The definition of WPC Embossing Board material in the American Society for Testing and Materials (ASTM) is: "a composite material mainly made of wood or cellulose as the basic material and plastic (or a variety of plastics)." It has many characteristics such as water resistance, corrosion resistance, conventional mechanical processing and plasticity, the use of recycled materials, and reuse. At present, the wood base materials used in the domestic manufacture of wood plastic mainly include wood flour, wood fiber, and other plant fiber scraps. The resin base materials mainly include polyvinyl chloride, polyethylene, and polypropylene. WPC Embossing Board products mainly include paving, fence, Interior decoration parts, building doors, cement templates, etc. At present, WPC Embossing Board products are developing in the direction of co-extrusion, embossing, and 3D printing.


Experiment procedure

The expected specimen size for WPC Embossing Board preparation is 28 mm × 13 mm × 2 mm, based on which material calculations and other operations are carried out.

(1) Wood flour pretreatment: First sieve the wood flour with 60 mesh and 80 mesh screens, and then weigh out a certain amount of wood flour for use; weigh 4% of the wood flour weight for the tetra butyl titanate coupling agent, dissolved in absolute ethanol and adjusted to a concentration of 30%. While stirring, spray the coupling agent solution on the wood flour, and then stir for 3 to 5 minutes to make it uniform. Put the stirred WPC Embossing Board wood flour into the oven and dry it at 60 ℃ for 3 hours.

(2) Mixing: Weigh the pretreated WPC Embossing Board wood flour according to a certain amount, then weigh the resin according to the wood-plastic ratio of 6: 4, and weigh the talc filler according to the amount of 20% of the total weight of wood flour and resin, then put the weighed WPC Embossing Board wood flour, resin and filler in a high-speed mixer at the same time, mix at a high speed at 80 ~ 90 ℃ for 8 minutes, and then discharge.

(3) Mixing: Gradually add the WPC Embossing Board mixture to an open mixer at a temperature of 130 to 140 ℃ within 2 minutes and mix for 6 minutes, and then discharge the tablets.

(4) Softening: Spread a certain amount of mixed materials in the mold, and then place it together with the WPC Embossing Board mold in a hot press at a preset temperature, and press it to the required value under the condition of a pressure of 4.0 MPa time.

(5) Shaping: Take the WPC Embossing Board material that has reached the softening time from the hot press together with the mold, and then quickly move it to a low-temperature press with a temperature of 55 ℃ and a pressure of 0.2 MPa for 20 minutes, and then take it out Obtain test pieces.
