Embodiment 1

[0028] Put the moso bamboo slices in the cooking pool, inject softening liquid into the pool to ensure that the bamboo slices are completely submerged in the softening liquid, then take out the soaked bamboo slices, clean them, put them in an atmospheric pressure cooking container for cooking for 1 hour, and then put The steamed bamboo slices are taken out, and the bamboo fiber splitting equipment is used to split the thickness of the bamboo slices from the middle along the longitudinal direction of the bamboo slices, and then use rollers to press them separately, and the fiber bundles connected together are dispersed by physical and mechanical action. Open, use equipment to repeatedly comb the rolled fibers into continuous fibers under unidirectional force, arrange the unidirectional long bamboo fibers evenly in the same direction, and sew the bamboo fibers into a certain width with a sewing machine and polyester thread. Uniform unidirectional fiber mat.

[0029] Add 35kg of ...

Embodiment 2

[0032] The preparation of moso bamboo unidirectional fiber felt is the same as in Example 1.

[0033] Add 35kg of epoxy resin E51, 10kg of polypropylene glycol diglycidyl ether, 1kg of acetic acid bisstearamide, 12kg of silicon carbide (3000 mesh), and 5kg of octabromodiphenylethane into the stirring tank, and stir evenly to obtain Component A; by weighing 7.5kg of isophorone diamine, 7.5kg of polyether ammonia D230, adding to the stirring tank, stirring at room temperature for 30 minutes, to obtain component B, component B, 2kg sodium hexametaphosphate Add it into the component A, and stir it evenly to get the epoxy resin adhesive.

[0034] 5 kg of epoxy resin adhesive was evenly coated on 10 kg of unidirectional bamboo fiber mats prepared by hand lay-up process, and the bamboo fiber mats coated with adhesive were arranged in parallel according to a certain angle. into a unidirectional fiber mat; then put the unidirectional fiber mat into the hydraulic press mold, and first ...

Abstract

The invention provides a preparation method of a fiberboard for a musical instrument bamboo fiber material. The preparation method comprises the following steps of 1), oxidizing and desugarizing natural plant fibers such as bamboo to obtain continuous bamboo natural fibers; 2), impregnating the surface modified continuous bamboo natural fibers with synthetic resin adhesive; and 3), carrying out compression molding on bamboo fibers impregnated with synthetic resin in a mold, taking forming curing temperature as the heat curing peak temperature of the synthetic resin adhesive, and preparing theplant fiber reinforced composite material after thermal curing molding. The preparation method of the fiberboard for the musical instrument bamboo fiber material has the advantages of low production cost, good mechanical property and good acoustic performance.

Description

technical field [0001] The invention relates to the technical field of musical instrument materials, in particular to a method for preparing a fiberboard for musical instrument bamboo fiber materials. Background technique [0002] With the improvement of living standards, people's requirements for the quality of life have also increased relatively. Music is an art that reflects the emotions of human real life. Especially now that the country advocates and promotes quality education, music quality education has begun to be widely carried out, and there is an increasing demand for musical instruments. Created utensils. Musical instruments include national musical instruments and Western musical instruments. The production of musical instruments is different from the production of general industrial products. He not only requires the product to have a reasonable and exquisite appearance, but also must have good acoustic quality, including timbre, music and prescribed pitch. T...
