Description

Composite plate with support and manufacturing method thereof

The present invention relates to a composite board for construction or decoration and a manufacturing method thereof, in particular to a composite board with a support and a manufacturing method thereof. Background technique

Due to the lack of raw materials for natural wooden boards, in order to save raw materials, the production of door panels, furniture, partition boards, flooring, packaging boxes, packaging boards, trays and other products, mostly using thin plates and keels, can save raw materials, Make thin plate have thick plate function. However, the combination of sheet and keel in such products has the following defects.

1. The combination of sheet and keel in this type of product is completed by nailing and bonding. Looseness, cracking, or disconnection are susceptible to stress during use. Especially for some thin plates, such as plywood and compression boards, they are adhered with adhesive glue, which tends to stick out a layer of skin and cause cracking. In particular, pallets often fall apart after being loaded and unloaded by a forklift for many times. Therefore, they must be constantly replaced, which limits the use of pallets.

2. The strength, toughness and deformation of these products after being stressed ^ [gen is difficult to meet the requirements. For example, there are strict inspections on the pallet inspection bureau. The strength is tested by diagonal free fall and forklift impact, the pallet is tested by flat weights at different positions to test its deformation, and the load test. Due to the materials used and the easy-to-deform and loose connection structure of the pallets, it is difficult to meet the test results.

3. As wood packaging products are affected by insect pests, export quarantine will be very troublesome. Especially in recent years, people are gradually looking for alternatives to Mudun products to avoid quarantine.

4. With the increasing scarcity of forest resources, the above-mentioned wood products are also increasingly plagued by resources and environmental protection, and their production costs are also getting higher and higher. And because the wooden packaging is not waterproof, flammable, and heavy, it is difficult to meet the needs of multiple uses of the product, which also limits the use of existing wooden products. Therefore, no matter whether it is nailing or bonding, it is difficult to ensure the strength, toughness and deformation of the product, and it is difficult to guarantee the quality. These have created problems for producers. Based on this situation, it is necessary to propose a new product to overcome the deficiencies and defects of the existing technology.
