example 1

[0026]Mix the rice husks and water at a mass ratio of 1:40 and soak them for 3 hours, filter to obtain water-soaked rice husks, freeze and pulverize the obtained water-soaked rice husks, and then dry them to a constant weight at a temperature of 110 ° C to obtain a dry Rice husk fibers, and then the obtained dry rice husk fibers were transferred to a carbonization furnace, and argon gas was introduced into the furnace at a rate of 90 mL / min for protection. After carbonization for 4 hours, continue to program the temperature at a rate of 0.5 °C / min to 500 °C, after thermal insulation carbonization for 5 hours, cool down to room temperature with the furnace, and discharge to obtain carbonized rice husk fibers; the mass ratio of lignin and mass fraction is 1:15. Add 35% formaldehyde solution into a four-necked flask, adjust the pH to 10.6 with sodium hydroxide solution, and after heating and refluxing for 6 hours, add urea-formaldehyde resin with 15 times the mass of lignin into t...

Abstract

The invention discloses a compound artificial board adhesive and belongs to the technical field of sheet material auxiliary agents. The compound artificial board adhesive disclosed by the invention isprepared from an inorganic binding agent, macromolecular resin, a biomass binding agent, a wetting agent and filling, wherein the inorganic binding agent is prepared from sodium silicate, nano oxideand carbonized rice husk fibers; the macromolecular resin is prepared from modified urea-formaldehyde resin, organic silicon, hydrogenated petroleum resin and a curing agent; the biomass binding agentis prepared from a plant extracting solution, sticky rice juice and humic acid; the plant extracting solution is obtained by mixing bagasse and fructus fici caricae, and extracting by utilizing de-ionized water. The compound artificial board adhesive provided by the invention has good water resistance and the bonding strength is effectively improved.

Description

technical field [0001] The invention discloses a composite wood-based board adhesive, which belongs to the technical field of board auxiliaries. Background technique [0002] With the development of the modern wood processing industry, the amount of wood-based panel adhesives has been expanding and the variety has increased, and it has become an important symbol of the development level of the wood industry in a region. [0003] At present, the "trialdehyde glue" represented by urea-formaldehyde resin, phenolic resin, and melamine-formaldehyde resin is the most widely used adhesive in the wood-based panel industry. These three types of adhesives all use formaldehyde as the synthetic raw material. Formaldehyde is regarded as one of the main sources of indoor air pollution. The pollution cycle is long and it is difficult to remove fundamentally, which has always plagued the development of the wood-based panel industry. With the improvement of environmental protection awarenes...
