Problems solved by technology

[0004] In the preparation process of anti-fold special boards in the prior art, the amount of glue used is about 30%. To prepare higher-density boards, a higher proportion of glue is required. There are problems in the preparation of high-density boards. One is the glue If the proportion is too high, it is difficult to mix the glue and fiber evenly. Second, if a large amount of glue is used, the board pressed by the hot press will bubble and delaminate.
[0005] The existing process requires a large amount of kraft paper, and the papermaking process needs to be carried out before production. During the papermaking process, the energy consumption is high, the pollution generated is large, and the impact on the environment is great. At the same time, the production cost of this process is high.

Embodiment 1

[0027] 1. Preparation of black fiber semi-finished products

[0028] Using tree branches, tree forks, straw, and bagasse as raw materials, it is first crushed to a size of 5mm, then peeled and desiliconized, then steamed and ground, and finally dried to make uniform fibers, no need to prepare kraft paper.

[0029] Calculated on the basis of 1000KG, weigh 850KG of modified phenolic resin, 60KG of magnesium hydroxide, 20KG of CIBA1010 antioxidant, and 70KG of nigrosine for later use, add magnesium hydroxide, CIBA1010 antioxidant, and nigrosine to the phenolic resin, mix well and heat Prepare an adhesive at 70°C to 80°C.

[0030] The previously prepared fibers must be dried first, and the weight ratio of the components is 60% of the fiber and 40% of the adhesive to be weighed for later use. The adhesive is gradually added by spraying with a glue sprayer and mixed with the fiber evenly. The number of nozzles is 7 ~8 pieces, pressure 6MPA;

Abstract

The invention relates to the technical field of decorative building materials, in particular to a method for preparing a high-density fibre panel. The method for preparing the fibre panel comprises the following steps of: preparing biological wastes containing fibers into uniform fibers; weighing 78 to 89 percent of phenolic resin and 11 to 22 percent of aid in a weight ratio, mixing uniformly, and heating to the temperature of 70 DEG C to prepare an adhesive; drying the fibers, adding the prepared adhesive gradually in a spraying mode, and mixing uniformly with the fibers; paving the fibers subjected to sizing, prepressing and performing hot-pressing to prepare a semi-finished product; and adding decorative adhesive film paper on the semi-finished product, performing the hot-pressing by a hot press, and forming to prepare the high-density fibre panel. The prepared fibre panel is a high-density decorative material panel with the density of over 1.45g / cm<3>, has the characteristics of abrasion resistance, boiling water resistance, fire prevention, ultraviolet ray resistance and the like, and is not deformed and discolored indoors and outdoors within 15 years.

Description

technical field [0001] The invention relates to the technical field of decorative building materials, in particular to a preparation method of a high-density combite board. Background technique [0002] Combeite board (also known as Kangbeite board) is a one-piece decorative material produced by dissolution and irreversible aging hardening under high temperature and high pressure. The board material has high stability, shockproof and drop resistance, cold and heat resistance, and has the characteristics of fire resistance, moisture resistance and smoke resistance. Even bathroom and toilet cubicles, sinks, reception counters, lockers, ceilings, desks and office cubicles in public spaces can all be made of anti-fold special boards. [0003] At present, kraft paper is the raw material for the preparation of Kangbei special board. It is made of multi-layer kraft paper soaked in phenolic resin and then dried with decorative colored paper treated with melamine under high temperat...
