Problems solved by technology

[0004] The technical problem to be solved by the present invention is that the current phenolic resin has high low-temperature brittleness, is easy to crack, and has poor impact resistance and crack growth resistance, especially cracks parallel to the fiber direction, which are easy to expand along the matrix or fiber-matrix interface, resulting in transverse fracture. The disadvantages of low energy and low toughness provide a preparation method for bamboo charcoal particles/hollow microspheres/phenolic resin ternary composite boards. The present invention is to split and dry

example 1

[0017] First, cut off the moso bamboo that has grown for more than four years, take the four middle nodes, split and crush them into bamboo strips with a length of 5 cm, a thickness of 2 mm, collect the bamboo strips and dry them in an oven at 100°C for 2 hours, then place them at 150 ℃ muffle furnace, carry out preliminary carbonization under the condition of nitrogen protection, the control time is 5h, after the initial carbonization, slowly raise the temperature to 450℃ at a rate of 10℃ / min, keep warm for 8h, let it naturally after the calcination is completed Cool to 20 DEG C, then it is rolled and sieved to prepare 80 mesh bamboo charcoal particles for subsequent use; then in parts by mass, 25 parts of ammonium nitrate, 20 parts of styrene monomer, 46 parts of deionized water, 5 parts of styrene monomer are selected respectively. One part of azobisisobutyronitrile and ~4 parts of ammonium lauryl sulfate were placed in a 5L stainless steel autoclave, and stirred and mixed f...

[0020]First cut off the moso bamboo that has grown for more than four years, take the four middle nodes, split and crush them into bamboo strips with a length of 5 cm, a thickness of 2.5 mm, collect the bamboo strips and dry them in an oven at 125°C for 2.5 hours, then place them in a Carry out preliminary carbonization in a muffle furnace at 210°C under the condition of nitrogen protection. The control time is 6.5h. After the initial carbonization, slowly increase the temperature to 520°C at a rate of 10°C / min, and keep the carbonization for 9h. After the calcination is completed Allow it to cool naturally to 25°C, then roll it and sieve it to prepare 100-mesh bamboo charcoal particles for later use; then select 16 parts of ammonium nitrate, 25 parts of styrene monomer, and 50 parts of deionized Water, 6 parts of azobisisobutyronitrile and 3 parts of ammonium lauryl sulfate were placed in a 5L stainless steel autoclave, stirred and mixed for 13 minutes to prepare the hollow mi...

Abstract

The invention discloses a preparation method for a bamboo charcoal particle-hollow microsphere-phenolic resin ternary composite plate, and belongs to the field of composite material preparation. The preparation method for the ternary composite plate comprises the steps that moso bamboo is taken to be split, dried, carbonized and rolled into particles for standby application; ammonium nitrate, styrene monomers, deionized water, azodiisobutyronitrile and ammonium lauryl sulfate are taken to be mixed in a high-pressure reaction kettle, sealing treatment is performed, nitrogen is introduced, vacuumizing is performed, vinylidene chloride is added for predispersion treatment, reacting under heating is performed, suction filtration is performed to obtain filter cakes, the filter cakes are washed by absolute ethyl alcohol, foamed under heating, dried and then mixed with the standby bamboo charcoal particles and a phenolic resin ammonium chloride solution, natural curing is performed on the mixture in a mould, and then the ternary composite plate is prepared. The preparation method has the advantages of being simple and little in pollution to the environment in the production process. The obtained product has the good mechanical property and heat stability and is little in low temperature brittleness, capable of resisting the temperature of minus 10 DEG C-380 DEG C, not prone to crack, good in impact resistance and anti-crack propagation capacity and high in toughness.

Description

technical field [0001] The invention relates to a preparation method of a bamboo charcoal particle / hollow microsphere / phenolic resin ternary composite plate, belonging to the field of composite material preparation. Background technique [0002] Phenolic resin is also called bakelite, also known as bakelite powder. Originally a colorless or yellowish-brown transparent substance, the market often adds coloring agents to turn it into red, yellow, black, green, brown, blue and other colors, with granules and powders. Resistant to weak acid and weak alkali, it will decompose in case of strong acid and corrode in case of strong alkali. Insoluble in water, soluble in acetone, alcohol and other organic solvents. It is obtained by polycondensation of phenolic aldehyde or its derivatives. In the 1980s and 1990s, my country's phenolic resin developed rapidly, and has formed a broad market. The products involve molding compounds, wood bonding, casting, insulating products, coatings,...
