Abstract
The present invention relates to a production method of melamine and bamboo wood phenol liquefied matter modified phenol formaldehyde resin. Its raw material composition includes (by weight portion) 250-500 portions of bamboo wood phenol liquefied matter, 0-500 portions of water, 50-500 portions of melamine, 500-1000 portions of aldehyde organics and 5-50 portions of catalyst. Said modified resin is suitable for making integrated circuit board, reinforced floor board, bamboo wood veneer board and brake disk, etc. Besides, said invention also provides the concrete steps of said production method.
Description
Technical field
The present invention relates to main is the method for raw material production resol by trimeric cyanamide, bamboo lignan liquefied substance, aldehydes.
Background technology
In recent years, the rise of the Wood liquefied technology of bamboo, the bamboo lignan liquefied substance product of this technology occurs thereupon, to liquefaction thing in the industrial problem how to use, by strong-willed person is paid close attention to.Through chemically examining with existing, containing main composition in the bamboo lignan liquefied substance is that methoxyl group phenol, 5 hydroxymethyl furfural etc. are multiple in conjunction with phenol and aldehyde bonded, use these and make the raw material of modified phenolic resins, and find out a corresponding cover technical process, its realistic meaning is arranged in conjunction with phenol with in conjunction with aldehydes." New Chemical Materials " the 31st volume the 12nd periodical of publishing in December, 2003 has been stepped on " research of cyanamid dimerization and cashew nut oil modified alkyd resin " literary composition that Li Benlin etc. writes, introduce in the literary composition, the resin that obtains can be used as the tackiness agent of various base-materials in the brake facing.The raw material sources of this method are inadequate, and synthetic method is easy not enough, and free formaldehyde and free-phenol are more, and be toxic, and are mobile not good enough, and it is difficult to store.
By retrieval, do not find interference applications of the present invention, do not find relevant commercially available product yet in China market.
Summary of the invention
The present invention is directed to the above-mentioned deficiency of prior art, design that a kind of raw material is competent, compliance with environmental protection requirements, synthetic method is simple, trimeric cyanamide and bamboo wood phenol liquified substance modified phenolic resin production method.
Above-mentioned purpose can be implemented with following measure: it is made up of following raw material and weight part thereof: 250-500 part bamboo lignan liquefied substance, 0-500 part water, 50-500 part trimeric cyanamide, 500-1000 part aldehydes organism, 5-50 part catalyzer; Earlier with bamboo lignan liquefied substance, water and aldehydes proportion requirement are by weight weighed, (formaldehyde can once always add or divide 2-3 adding to add the reactor stirring, need during this time to heat up respectively, insulation, cooling), adding catalyzer transfers pH value to 8.0-9.5, evenly heat up, the still temperature rise adds trimeric cyanamide during to 40-45 ℃ and heats up, the control heat-up rate, after in the time of 90-95 ℃, being incubated 30 minutes, carry out molten water multiple mensuration or water chaotic degree and measure, the molten water multiple when 20 ℃ of water temperatures is to 1-0.7 times, or water chaotic degree is checked when globe is arranged, terminal point is promptly arrived in reaction, the insulation of process reaction during this time 40-60 minute, cooling adds an amount of solvent immediately, when being cooled to 45 ℃, blowing is finished product.
The also available following measure of above-mentioned purpose comes perfect: said aldehydes organism is formaldehyde and/or furfural; Said catalyzer is NaoH, KOH, Ba (OH)
2, at least a in the bases thing such as ammoniacal liquor.
Embodiment
The present invention will now be further detailed embodiment: raw material and the weight part proportioning thereof with ten embodiment is listed as into following table earlier.
Embodiment 1 (consulting weight part proportioning numeral in the table):
Earlier with bamboo lignan liquefied substance 400 weight parts, the furfural of water 400 weight parts and 600 weight parts adds reactor and stirs, add that about 8 weight part NaOH transfer pH value evenly to be warming up to 40-45 ℃ to 8.0-9.5, adding 300 weight part trimeric cyanamides again continues to heat up, but need the control heat-up rate, be incubated during to 90-95 ℃, and note measuring and the control pH value, be incubated after 30 minutes, carrying out the mensuration or the water chaotic degree of molten water multiple measures, when water temperature during at 20 ℃ molten water multiple to 1-0.7 doubly or the opacity check when globe is arranged reaction arrived terminal point, the insulation of process reaction therebetween 45-60 minute, cooling immediately, when cooling to 45 ℃.
Embodiment 2-10 can make this modified phenolic resins with embodiment 1 identical method by the weight part proportioning of last each raw material of table.
The selected of size as for the proportional quantity of each material composition will be considered as a whole according to the key elements such as advantages and disadvantages that the height of cost, the degree of perfection of reaction, the physicochemical property that makes glue and these performances bring for production, environmental protection, benefit.Bamboo lignan liquefied substance has been added, the cost-saving, and toughness improves, but storage period is short; Fire-retardant, attrition resistant advantage that trimeric cyanamide has, but hardness and fragility are big, the poor stability of glue; Aldehydes has been added the degree of crosslinking height, has been become glue fast, but release formaldehyde is unfavorable to HUMAN HEALTH; Catalyzer is too much very few all can to cause waste.Selecting a kind of or several problems in the aldehyde material, mainly is that, colloid amount simplified and traditional from cost, technology considered and decided.Amid all these factors, the present invention is preferred with embodiment 9.For sufficient reacting, improve the polymerization degree, so need add water; But this glue is applied to make brake facing, emery wheel, does not then add water.
Scheme with embodiment 9 is that example is described further below, and the modification aldehyde urea formaldehyde outward appearance of making is the brown colloid, and storage period, pH value was 8-9 greater than three months, and free phenol is 0.5-5%, and free formaldehyde is less than 1.0%.
This resin can be widely used in surface-mounted integrated circuit, consolidated floor, glued board, medium density fibre board (MDF), automobile brake sheet, the production of dipping glue.The trimeric cyanamide that adopts present method to make compares with bamboo wood phenol liquified substance modified phenolic resin in the contrast material that to be with trimeric cyanamide and amine shell oil that modified phenolic resins that raw material makes has synthetic method simple, abundant raw material, cost is low, advantages such as compliance with environmental protection requirements.
