Embodiment Construction

[0031] The present invention will be further described below in conjunction with the examples, but the protection scope of the present invention is not limited to the following specific examples.

[0032] The preparation method of a Chinese fir core fire-resistant, flame-retardant and environmentally friendly blockboard provided by the present invention comprises the following steps:

[0033] (1) Saw fir into long strips with a length of 200mm-800mm, a width of 30mm-70mm, and a thickness of 8mm-15mm, and pile them up and send them to the drying room for baking so that the moisture content of the strips reaches 12. within %;

[0034] (2) Use a comb machine to comb the two ends of the slats, and then butt the slats into 2470mm slats;

[0035] (3) Preparation of adhesive A: 100 parts by weight of urea-formaldehyde resin, 30 parts by weight of fire retardant, and 25 parts by weight of flour were fully stirred and evenly prepared into adhesive A for subsequent use;

[0036] (4) A...

Abstract

The invention discloses a Chinese fir core fireproof and flame-retardant environmental-friendly core-board and a preparation method thereof. The preparation method comprises the steps that two ends ofdried Chinese fir board strips are combed by a rack shaping machine, and then the board strips are butted into required lengths; adhesives with fireproof flame retardants are coated on the side surfaces of the butted board strips, and the board strips are fed into a four-side lateral pressing machine for compression to form board cores after being assembled to required widths; fireproof and flame-retardant penetrating fluid is uniformly sprayed or coated on the two surfaces of the board cores; the board cores are fed into a drying chamber for baking, cooling and shaping; slotting is carried out on the front surfaces and the back surfaces of the board cores, and slots are filled with the adhesives with the fireproof flame retardants; the front surfaces and the back surfaces of the board cores are painted with the adhesives and covered with single boards; stored slabs are subjected to hot pressing after being pre-compacted; the front surfaces and the back surfaces of sand flat slabs aresubjected to rubber coating and pasted with veneers and being subjected to hot pressing; and finished products are obtained after cooling and shaping. According to the Chinese fir core fireproof andflame-retardant environmental-friendly core-board and the preparation method thereof, through the technologic innovation, prepared core-boards can achieve a quite good fireproof and flame-retardant effect, and the fireproof and flame-retardant grade reaches grade B1.

Description

technical field [0001] The invention relates to the field of decorative boards, in particular to a fir core fireproof, flame retardant and environmentally friendly blockboard and a preparation method thereof. Background technique [0002] With the continuous development of my country's economic construction and the improvement of people's living standards, people have put forward higher requirements for the aesthetics, comfort and other functions of architectural and decorative panels. Blockboard is a kind of board made of natural wood veneer and solid wood panel through manual processing. Because of its uniform specifications, light weight, easy processing, good nail holding power, and no deformation, it is widely used in construction and interior decoration. field is widely used. However, blockboard is a flammable material, which does not have the characteristics of flame retardancy or delayed combustion in a fire, and there is a great potential safety hazard. Contents ...
