Bamboo-plastic composite board hot press and hot press process

Abstract

The invention relates to a bamboo-plastic composite board hot press and a hot press process. The hot press comprises a support, a bottom die fixedly mounted on the support, a press plate, a hydraulicdevice that drives the press plate to move up and down, and a temperature control device that provides heat energy or cooling for the press plate and the bottom die, wherein when the press plate is pressed into the bottom die, the bottom die and the press plate form a sealed hot press space; an air inlet capable of opening and closing communicates with the hot press space to inject pressurized gasinto the hot press space; injection devices are provided respectively below the bottom die and above the press plate; injection ports are provided respectively below the bottom die and on the press plate; and the injection devices separately inject into the hot press space from the injection ports. The product is a hot press product with both the toughness of bamboo products, and good plasticityas well as surface quality of plastics. At the same time, the bamboo-plastic composite board produced has strong strength and rigidity, overcomes the defect of poor durability of bamboo, and does notrequire the use of glue to effectively prevent harm to human health.

Description

technical field [0001] The invention relates to the field of bamboo and wood processing, in particular to a bamboo-plastic composite board hot press and a hot pressing process. Background technique [0002] Bamboo grows fast and can effectively replace solid wood. It has a significant effect on reducing the price of consumer goods and protecting the environment. Hot-pressed bamboo products are widely used in daily life, such as cutting boards, furniture, etc. Existing hot-pressed bamboo products need Glue is used to bond bamboo products, and then form a firm whole by hot pressing. The glue contains a lot of harmful substances, such as formaldehyde and other carcinogens; and a very large pressure is required in this process. Long-term pressure holding can be carried out, the equipment requirements are high, the risk is high, the processing cost is high, and the efficiency is low; in addition, the bamboo products produced by this method still have inherent defects of bamboo, s...

[0002] Bamboo grows fast and can effectively replace solid wood. It has a significant effect on reducing the price of consumer goods and protecting the environment. Hot-pressed bamboo products are widely used in daily life, such as cutting boards, furniture, etc. Existing hot-pressed bamboo products need Glue is used to bond bamboo products, and then form a firm whole by hot pressing. The glue contains a lot of harmful substances, such as formaldehyde and other carcinogens; and a very large pressure is required in this process. Long-term pressure holding can be carried out, high equipment requirements, high risk, high processing cost, and low efficiency; in addition, the bamboo products produced by this method still have inherent defects of bamboo, poor durability, such as easy to dry, crack, stratify or mold
