Abstract
The present invention discloses a special-purpose cementing agent for match. It is characterized by containing the following ingredients: thermosetting resin, polyvinyl alcohol, carboxymethyl cellulose sodium, sodium dodecyl benzene sulfonate and methyl alcohol. After practical application, said cementing agent doesn't absorb moisture, and can resist mould and resist moth, and is favorable for environmental protection, and can fully meet the requirements of cementing power, foaming degree and gelling speed for match head. The use of said cementing agent can shorten the technological process for making match, and can reduce the comprehensive cost of matches by above 20%.
Description
The present invention relates to a kind of binding agent, particularly a kind of special purpose cementing agent for match.
Traditional match medicine head all is to make binding agent with gelatin (hide glue), though this binding agent can satisfy the cohesive force of match medicine head, the requirement of foam degrees and gelation rate, but it has the following disadvantages: at first be the gelatin deliquescence that very easily absorbs water, the moisture absorption easily taking place in the storage process, go mouldy and the situation of damaging by worms, brings difficulty for the storage of gelatin and goods thereof.Secondly make match medicine head binding agent with gelatin, need heating for dissolving before the use, in use need be incubated, the high slightly then medicine of temperature head diminishes, and does not reach specification of quality, and temperature is low slightly, then the medicine head is excessive, causes waste of raw materials, and above-mentioned situation causes the match manufacture craft numerous and diverse, power consumption is high, and quality is difficult for guaranteeing.Also useful gelatin is made match medicine head binding agent, must like this, not only contain harmful heavy metal chromium in the match, and contain a large amount of chromium ions, contaminate environment in Matches Factory's waste discharge with the potassium bichromate jelly of tanning.Gelatin complex manufacturing in addition, price is expensive.Thereby people begin to seek to substitute gelatin with chemical glue and make match medicine head binding agent in recent years, and classify it emphasis problem of the industry as, but because of a variety of causes, have not yet to see useful chemical glue and substitute the report that gelatin is made match medicine head binding agent.
The objective of the invention is to overcome the deficiencies in the prior art, a kind of making, easy to use is provided, be easy to store, cut down the consumption of energy and be beneficial to the special purpose cementing agent for match of environment protection.
Purpose of the present invention realizes by following technical proposals:
Get thermosetting resin 60-85 weight part, 9-15% polyvinyl alcohol solution 15-20 weight part, 2-6% carboxymethylcellulose sodium solution 5-15 weight part, Sodium dodecylbenzene sulfonate 0.1-1 weight part, methyl alcohol 0.6-17 weight part, and the caustic lye of soda of the hydrochloric acid solution of 1N and 1N is standby.
Said thermosetting resin is meant Precondensed UreaFormaldehyde Resin, any in resol or the terpolycyantoamino-formaldehyde resin.
Free aldehyde can add the heavy melamine resin of 0.05-5% of thermosetting resin weight greater than 0.5% o'clock in the thermosetting resin.
Said methyl alcohol also can substitute with ethanol or butanols.
During preparation, prepare polyvinyl alcohol solution and the 2-6% carboxymethylcellulose sodium solution of 9-15% earlier, to place stirred vessel as the main component thermosetting resin of special purpose cementing agent for match again, transfer pH value to 2-3 with the hydrochloric acid solution of 1N, adding methyl alcohol again stirred after 30-50 minute, transfer pH value to 7.5-8 with the 1N caustic lye of soda, after restir 30-45 minute, add polyvinyl alcohol solution, carboxymethylcellulose sodium solution, Sodium dodecylbenzene sulfonate more successively, stir after 1.5-3 hour, can packing store.
From such scheme, as can be seen, the objective of the invention is to realize.Precondensed UreaFormaldehyde Resin or resol or terpolycyantoamino-formaldehyde resin are the main bodys of special purpose cementing agent for match, and it produces etherification reaction with alcohol under acidic conditions: as Precondensed UreaFormaldehyde Resin
Appropriateness etherfied Precondensed UreaFormaldehyde Resin, resol or terpolycyantoamino-formaldehyde resin both improved its storage stability, solvability and with the compatibility of other material, obtain corresponding film forming speed again, quality product is guaranteed, and the etherificate time was advisable with 30-50 minute.Transfer pH value to 7.5-8 with sodium hydroxide, above-mentioned etherificate stops at once.Polyvinyl alcohol is to make whipping agent on the one hand, on the other hand the stability of the thermosetting resin after the etherificate is further strengthened, its amount is too much unsuitable, too much can make match starch bubble, match medicine head is broken, and the very few foaming effect that do not have again makes match be difficult for striking, Xylo-Mucine mainly is as thickening material, makes the match medicine head size one of the making smooth surface of making peace.Sodium dodecylbenzene sulfonate mainly is the surface tension of regulating special purpose cementing agent for match, cooperates with Xylo-Mucine to guarantee match medicine head size uniformity.
When free formaldehyde content in the thermosetting resin greater than 0.5% the time, can produce hormesis to human body, unfavorable to HUMAN HEALTH, adding melamine resin can produce addition condensation reaction with free aldehyde, and reaches the content that reduces free aldehyde.
When special purpose cementing agent for match uses, needn't change the mixing method of former match medicine head, only need special purpose cementing agent for match and ammonia chloride by 100: the weight ratio of 0.7-1.4 is mixed the former animal glue of replacement and is got final product, and need not add gentleness and be incubated.After testing, the viscosity of this binding agent is that 4000-8000 goes through pool, and foam degrees is every milliliter of 15-25 cubic centimetre, and stability is 15-30 minute, requirement that fully can match medicine head binding agent.
Man Matches Factory is on probation through number, and effect is fine.Replace gelatin with it, in the match fuse produces, need not use heavy potassium acid chromium, be beneficial to environment protection, secondly shortened match manufacture craft flow process with special purpose cementing agent for match of the present invention, easy to operate, saved energy consumption.Also having special purpose cementing agent for match is Chemical Felter, and it is non-hygroscopic, and anti-mildew becomes, and is anti-insect, and itself and goods excellent storage stability thereof generally do not need protection against the tide especially, mildew-resistant, mothproof measure.In addition,, thereby can reduce price is more expensive in the match medicine head ignition compound-Potcrate more than 10%, add the energy consumption that does not need heat tracing, can make the match comprehensive cost descend about 20% because the characteristic of autoigniting of special purpose cementing agent for match is good than gelatin.Have good social benefit and economic benefit.
