example 1

[0025] First, the coconut carbon fiber is placed in a fluidized bed reactor, and nitrogen with a trimethylaluminum content of 10% is passed into the fluidized bed reactor at a rate of 100mL / min. Into the fluidized bed reactor, nitrogen with a moisture content of 5% was passed into the fluidized bed reactor for 15 minutes, and then the material was discharged and dried to a constant weight to obtain coated coconut charcoal fibers; Add coconut carbon fiber and casein into the beaker, then move the beaker into a magnetic stirrer with digital speed measurement and constant temperature, stir and impregnate at a temperature of 40°C and a speed of 500r / min for 30 minutes to obtain a mixed solution, and then filter the obtained mixed solution. To obtain modified coated coconut carbon fiber; add polyallylamine emulsion and polyaspartic acid into a three-necked flask according to the mass ratio of 1:5, and then move the three-necked flask into a digital speed measuring constant temperatu...

Abstract

The invention discloses poplar plywood and a preparation method thereof and belongs to the technical field of building materials. Coconut carbon fibers are placed in a fluidized bed reactor, nitrogencontaining trimethylaluminum is pumped into the fluidized bed reactor, after continuous pumping for 30-60 min, nitrogen containing water is pumped into the fluidized bed reactor, and after continuouspumping for 5-15 min, discharging and drying are conducted to obtain coated coconut carbon fibers; the coated coconut carbon fibers and casein are mixed, soaked and filter to obtain modified coated coconut carbon fibers; poly(allylamine) emulsion and polyaspartic acid are heated and stirred at a high speed, then high speed centrifugation is conducted, and polyaspartic acid microspheres are obtained; an adhesive, water, the modified coated coconut carbon fibers, nano emulsion, polyols, castor oil acid, the polyaspartic acid microspheres, hexanediamine and a silane coupling agent are mixed and stirred, and a modified adhesive is obtained; and then the poplar wood plate surface is treated, a core plate is glued, assembling, preheating, hot pressing and post-processing are conducted, and the poplar plywood is obtained. The poplar plywood has excellent waterproof and mechanical properties.

Description

technical field [0001] The invention discloses a poplar plywood and a preparation method thereof, belonging to the technical field of building materials. Background technique [0002] After the implementation of the natural forest protection project, in order to solve the fundamental problem of timber shortage, it was alleviated to a certain extent by vigorously developing artificial forests. As a fast-growing and high-yielding tree species, poplar provides a large amount of raw materials for the new development of the forest industry. As one of the excellent artificial fast-growing timber species, poplar has high ecological value and industrial utilization value. At present, researchers have scientifically and rationally developed and utilized poplar fast-growing forests, which has promoted the rapid development of poplar processing industry. However, poplar generally has the characteristics of unstable size, easy deformation, monotonous material color, low density, and lo...
