Abstract
The resorcinol-phenol liquefied bamboo-wood matter-formaldehyde resin glue is produced with the materials including bamboo-wood powder 40-60 weight portions, phenol 80-120 weight portions, water 50-150 weight portions, proper amount of catalyst, aldehyde 80-180 weight portions and resorcinol 30-90 weight portions. The production process includes the following steps: the reaction of industrial resorcinol and bamboo-wood powder through heating and in the presence of catalyst to produce phenol liquefied bamboo-wood matter; adding water and industrial aldehyde and regulate pH value to react at controlled temperature for 0.5 hr; and adding industrial resorcinol to react under certain pH value and temperature for 2 hr. The modified resin glue may be used for various bamboo and timber products, and has high adhesion, low cost and other advantages.
Description
Technical field
The present invention relates to Resorcinol, bamboo and wood phenol liquified object, formaldehyde copolymerization and must modified alkyd resin glue and production method thereof.
Background technology
Existing Resorcinol-formaldehyde resin adhesive is stronger to the bounding force of bamboo and wood products, and can in middle temperature (90-100 ℃) or room temperature (20 ℃), solidify, the good prospect of using is arranged, but because of it costs an arm and a leg in large span, large format, the processing of superthick sheet material, the people is stepped back and be difficult to promote.In " isophthalic aldehyde-phenol-formaldehyde resin preparation and performance study " literary composition that " chemistry of forest product and industry " published in December, 1999 the 19th volume is the 4th interim, publication Wang Chun roc etc. writes, introduced the above-mentioned feature of this Resin adhesive of producing with chemical reagent purely.Studies show that through the scholar, the phenol liquefaction of bamboo wood, timber, its Mierocrystalline cellulose, lignin reaction's generation methoxyl group phenol, 5 hydroxymethyl furfural etc. are multiple in conjunction with phenol and aldehyde bonded, how to utilize by these one-tenth in the phenol liquified object of bamboo and wood material and assign to substitute or the alternative phenolate worker raw material of part, make above-mentioned Resorcinol modified resin glue, still open and relevant in kind appearance of no data.
Summary of the invention
The pure chemistry reagent glue cost height that makes at prior art, cost an arm and a leg, and the deficiency that is difficult to application, the objective of the invention is to design and a kind ofly make raw material with bamboo and wood liquefaction thing, replace or partly replace the phenols industrial chemicals, with the method for Resorcinol, formaldehyde copolymerization production modified resin glue.
The present invention can realize with following measure: a kind of Resorcinol-bamboo lignan liquefied substance-formaldehyde resin gel, the raw material and the weight part thereof that adopt are: the bamboo wood powder of 40-60 part, the phenols of 80-120 part, 50-150 part water, proper catalyst, the aldehydes of 80-180 part, 30-90 part Resorcinol, concrete production stage is as follows:
A, pour the technical pure phenols into reactor;
B adds catalyzer;
C, bamboo and wood is ground into powdery, claim the weight part of ratio requirement, pour reactor into, heat to 100-150 ℃ and liquefied 1 hour;
PH=7.0-8.0 is regulated in d, the bamboo lignan liquefied substance with generating, water and the reaction of industrial aldehydes, and temperature of reaction kettle is controlled at 70-80 ℃, reaction 30min;
E, add industrial Resorcinol again in this reactor, controlled temperature 60-90 ℃, PH is adjusted to 9.0-9.5, the about 30min to 2h of reaction.
The present invention can come perfect with following measure: said bamboo wood powder particulate size specification is the 30-300 order; Said phenolic material is at least a in phenol, methylphenol, the xylenol; Aldehydes is at least a in formaldehyde, acetaldehyde, the furfural; Catalyzer be select in acid, alkali, the divalent-metal ion a kind of; Acid is to select in the strong acid such as hydrochloric acid, sulfuric acid, also can select a kind of in weak acid such as phosphoric acid, boric acid.
Embodiment
Illustrated with example below the present invention.Following table is raw material and the weight part proportioning table thereof of five embodiment:
Embodiment 1 (consulting weight part proportioning numeral in the table):
Pour the industrial phenol of 100 weight parts (being called for short part) into reactor earlier, add appropriate hydrochloric acid and make catalyzer, to be ground into 30-300 purpose bamboo and/or wood powder simultaneously and pour reactor into, and heat to 100-150 ℃ and liquefied 150 parts bamboo lignan liquefied substance of generation 1 hour.In this reactor, add 137 parts of formaldehyde again, regulate PH to 7.5, add 80 parts of water, temperature is controlled at 70-80 ℃, react and added 66 parts of industrial Resorcinols in 30 minutes again, temperature is controlled at 60-90 ℃, regulates pH value to 9.0-9.5, reaction 0.5-2h Resorcinol-bamboo lignan liquefied substance-formaldehyde resin adhesive.
Embodiment 2-5 can make with embodiment 1 same procedure by the raw material and the weight part proportioning thereof of routine preface in the table.
The bamboo wood powder is relevant in kind, temperature of reaction and the time of the add-on of the degree of the add-on in when liquefaction and bamboo age, age of tree size, water ratio, pulverizing, other component, catalyzer.During synthetical glue,, its original effect is arranged respectively, say that generally use divalent-metal ion, the set time of the glue that then makes is the shortest though acid, alkali, this three classes material of divalent-metal ion all can be made catalyzer; Acid as catalyst is more a little than alkali as a catalyst complex process, has need before adding Resorcinol alkalescence to be adjusted to slightly acidic, thus the water-soluble problem that slightly descends; Alkali as a catalyst bonding strength and wood-breaking rate are higher.Therefore catalyzer will be taken all factors into consideration each factor and selectes.The add-on of other composition also has the problem of multifactor consideration, as it is low to add the formaldehyde cost, but the staging life of glue is short; The curing of glue under the favourable room temperature condition of Resorcinol, but raw materials cost height, from the self-vulcanizing effect requirements of glue, the Resorcinol that adds 5 weight parts is also passable, but the glue that makes like this can only be used for the gummed that the structure material of load-bearing such as crossbeam is pasted, can not be done on plane such as three-ply-wood.Whether relevant the length in reaction times is with sufficient reacting; The self-vulcanizing time of glue, pH value raises and to shorten during with glue, takes all factors into consideration that to fix on 9.0-9.5 more suitable.
Among above-mentioned five embodiment, preferred with embodiment 1.The glue that this example makes, solid content is greater than 40%, pH value 9.0-9.5, and the outward appearance Vandyke brown, storage period, free phenol was less than 2% greater than two months, and free aldehyde is less than 0.5%, and bonding strength is greater than 7.0Mpa.
The modified resin glue that adopts present method to make, with the chemical preparations that waste material substitutes or the part substitute valence is high in the bamboo and wood processing, and utilize the effective constituent in the bamboo lignan liquefied substance, in the bamboo wood glue is sticking, have sufficient avidity, gummed power is strong, and cost is low, help environment-friendly type production, to applying the good prospect of bringing.
