Embodiment Construction

[0018] A molding process for composite particle boards, comprising the steps of:

[0019] S1: Use a crusher to crush the board raw materials into wood chips with a particle size of 12mm or less;

[0020] S2: Mix and stir the particle wood chips and the fireproof adhesive in a ratio of 1:1.2 to obtain a mixture in which the particle wood chips adhere to the fireproof adhesive;

[0021] S3: Transport the mixture to a forming mold for cold pressing with a pressure value of 10Mpa. The mold includes a female mold with a groove and a male mold with a boss corresponding to the groove. After 30 hours, the fireproof adhesive is solidified and formed;

[0022] S4: After the fireproof adhesive is cured and molded, demoulding is performed, and placed at room temperature for 3 days for health preservation until the fireproof adhesive completely penetrates into the wood fiber structure of the particle wood chips;

[0023] S5: Dry the cured formed board naturally or at a low temperature of...

Abstract

The invention provides a forming process of a composite particle board. The forming process comprises the following steps that S1, board raw materials are crushed into particle wood scraps through a crusher; S2, the particle wood scraps and a fireproof adhesive are mixed and stirred to be uniform according to the proportion of 1:0.8 to 1:1.2, and a mixture with the fireproof adhesive attached to the particle wood scraps is obtained; S3, the mixture is conveyed into a forming mold to be pressed, and the fireproof adhesive is cured and formed; S4, after the fireproof adhesive is cured and formed, demolding is carried out, and the board is placed at normal temperature to be preserved; and S5, the preserved formed board is naturally aired or dried at low temperature. According to the forming process, by improving the viscosity of the fireproof adhesive, the cure-forming time and the regularity of the grain size of the raw materials, the forming time of the board is shortened, pressing canbe carried out at the normal temperature, heating power is not needed, and energy saving and environmental friendliness are achieved.

Description

technical field [0001] The invention relates to a plate processing technology, in particular to a forming process of a composite particle plate. Background technique [0002] Particle board is a wood-based panel that is made of wood or other lignocellulosic materials and glued under heat and pressure after applying adhesives. Most of the raw materials of the existing particle board molding process are pressed by irregular shavings. In addition, due to the viscosity of the fireproof adhesive, the mixing work in the early stage of pressing has a certain impact, and it needs to be It can only be formed under the combined action of heat and pressure, which consumes a lot of energy and takes a long time to cure the fireproof adhesive. Therefore, the output cannot be raised temporarily, and it cannot be supplied to the market in large quantities. Contents of the invention [0003] The invention proposes a molding process of a composite particle plate, which does not need hot pr...
