Problems solved by technology

The wood-plastic composite materials (such as Japan's Ain wood) that started from the chemical industry have taken a step forward in technology, but there are many important defects, which have caused the wood-plastic industry to fail to achieve great development. The defects mainly include: 1. Wood-plastic materials The main technology is plastic modification. Wooden materials are only used as fillers, while unmodified woody materials have poor compatibility with plastics. Compared with low-molecular mineral fillers such as calcium carbonate, the use value of woody materials is much lower. Many; 2. It is difficult to extrude the material with wood material as the filler, the product quality is not high, and the scrap rate is high; 3. The variety of plastics used is very narrow, and the requirement is a single type of pure plastic, and it is difficult to process when mixed with other types; 4. Due to the fact that it is mainly made of plastic and difficult to process, the production cost of wood-plastic products is very high. Compared with other materials, it has no price advantage and it is difficult to enter the market

Embodiment 1

[0029] Embodiment 1, take wood powder, polyethylene (PE), stearic acid as raw material to prepare polymeric wood material

[0030] The first step, material preparation

[0031] Stearic acid can be purchased in chemical raw material stores for industrial use.

[0032] Polyethylene (PE) Buy new PE pellets at plastic stores, or use recycled flakes. Generally, you can buy oil barrels, soy sauce barrels, baby bottles, plastic wine bottles, etc. from the plastic recycling department, and then use a plastic crusher to grind them into flakes and wash them with clean water or alkaline water. While cleaning, materials can be selected. Compared with PE and other engineering plastics, the specific gravity is lighter and can float on the water. After cleaning, it can be directly bagged and waited for use.

[0033] The second step, wood flour modification: wood flour should be plant material with cellulose, hemicellulose and lignin as the main components. Sawdust, shavings, peanut shells...

Embodiment 2

[0041] Embodiment 2, modified wood flour performance test

[0042] The formula of the present invention: 200 kilograms of modified wood flour, 20 kilograms of PE-based sheet plastics, 17 kilograms of particles granulated from recycled agricultural film, 5 kilograms of stearic acid and paraffin wax.

[0043] Comparative formula: 300 kg of ordinary wood flour, 60 kg of PE-based sheet plastic, 51 kg of agricultural film pellets, 7.5 kg each of stearic acid and paraffin.

[0044] The ZC-75 co-rotating twin-screw granulator assembled by Jiangsu Wuxi Shinan Wood Plastic Processing Co., Ltd. was selected for granulation. The first to sixth zones and the head temperature were set to 110°C, 140°C, 148°C, and 150°C, respectively. , 155° C., 160° C., 162° C., and other operating procedures are the same as in Example 1.

[0045] result:

[0046] 1, granulation property: more than 95% of the particles produced by the formula of the present invention are granules, while more than 70% of t...

Embodiment 3

[0056] Embodiment 3, single-screw granulation test

[0057] Invented formula: 60 kg of modified wood powder, 20 kg of agricultural film material, 20 kg of PE sheet material, 2.5 kg of stearic acid, 2.5 kg of paraffin, and 0.5 kg of iron oxide red;

[0058] Comparative formula: 60 kg of ordinary wood flour, 20 kg of agricultural film material, 20 kg of PE sheet material, 2.5 kg of stearic acid, 2.5 kg of paraffin wax, and 0.5 kg of iron oxide red;

[0059] The YH-TD single-screw granulator produced by Beijing Yuquan Tuochuang Environmental Protection Technology Development Center was selected for granulation. The results showed that the granules obtained from the invented formula were soft and sticky, and the smoke was small during the granulation process; angry.

[0060] Use the single-screw granulator produced by Jiangsu Wuxi Shinan Wood Plastic Processing Co., Ltd. to produce 16mm thick hollow floor with the obtained particles:

[0061] When the particles obtained by the f...

Abstract

The present invention discloses a xylon polymerized composite material and its preparation method. The xylon polymerized composite material provided by said invention contains 65-85 wt% of modified xylon raw material, 10-30 wt% of thermoplastic material and 5-10 wt% of additive. The modified xylon raw material is obtained by spraying reactive initiator into the broken xylon raw material, sealing and stacking the above-mentioned material. Said xylon polymerized composite material can be made into various products instead of various plastics and wood material.

Description

technical field [0001] The invention relates to a wood polymer composite material (referred to as polymer wood) and a preparation method thereof. Background technique [0002] Wooden raw materials, like cement, steel, and plastics, are one of the indispensable basic raw materials for modern social and economic development. In 2003, my country produced 45.53 million tons of wood-based panel materials, making it the world's largest producer. With the development of the national economy, the demand and production will increase. At present, the basic raw materials of artificial wood have problems such as insufficient supply of wood, backward production technology, large amount of waste discharge in the production process, release of toxic substances during use, and serious pollution. On the other hand, there are plant raw materials that are equivalent to five to seven times the wood production in my country and can produce woody basic raw materials, which are wasted year after ...
