Description
Technical field
The present invention relates to a kind of furane resins more particularly to a kind of self-hardening furan resins.
Background technology
Furane resins are made of in a kind of structure containing furan nucleus, are modified furfuryl alcohol by furfuryl alcohol and phenol, urea or various aldehyde
Thermosetting resin, casting is exactly one kind therein with self-hardening furan resin, and casting under normal circumstances is with self-hardening furan resin
It is faint yellow to amber transparent or translucent uniform liquid.Casting self-hardening furan resin can make sand by acid catalysis at room temperature
Type hardens, and is a kind of binding agent that casting industry is the most frequently used, application amount is maximum, its main feature is that moulding is simple, sand mold collapsibility is good,
Regenerating used reclamation rate is high, resin sand intensity is high, smell is small.At present, the preparation of casting self-hardening furan resin, is primarily present chaff
A series of problems, such as alcohol addition height, low production efficiency, secondary pollution.Therefore the cost of resin is influenced very big by furfuryl alcohol.System
The step of standby furfuryl alcohol, mainly hydrolyzes the renewable agricultural and sideline product such as corncob and crop straw under catalyst action, is converted into
Pentose；Pentose generates furfural through cyclodehydration；Furfural obtains furfuryl alcohol after catalytic hydrogenation again.Since preparation method is cumbersome, so
The manufacturing cost of furfuryl alcohol is higher.In addition, corncob and crop material are seasonal agricultural product, cause the price fluctuation in furfuryl alcohol market
Property is larger.On the other hand, there are the problems such as yield is low, waste water and gas is seriously polluted by the preparation process of furfural.Therefore there is an urgent need for prepare
Suitable furfuryl alcohol substitute is used to prepare furan resin for casting, is allowed to that original performance can not only be kept, and can significantly drop
The cost and environmental protection of low furan resin for casting.
The content of the invention
In view of the foregoing drawbacks, it is an object of the invention to provide a kind of manufacturing cost is cheap, original performance, production effect are kept
Rate is high, reduces a kind of self-hardening furan resin of secondary pollution.
The technical solution adopted in the present invention is therefore：
Including following components and each component parts by weight：Phenol 12-27 parts by weight, urea 0.5-20 parts by weight, furfuryl alcohol 30-105
Parts by weight, furfuryl alcohol substitute 10-25 parts by weight, formaldehyde 8-22 parts by weight, acetone 8-22 parts by weight, reinforcing agent 0.1-0.5 weight
Part.
As being further improved for above-mentioned technical proposal, the furfuryl alcohol substitute is made by following steps：By 50 weight
Any combination more than one or both of part six-carbon monosaccharide and disaccharides containing six-carbon monosaccharide structural unit, polysaccharide is dissolved in 15
In~90 parts by weight water, 0.1~26 parts by weight phenols and 5~20 parts by weight acid are then added in, in 60~95 DEG C of temperature conditionss
It is lower reaction 0.5~8 it is small when after, after pH value is adjusted to 7.5~9.5 after being cooled to 25~85 DEG C add in 0.1~15 parts by weight of formaldehyde,
Be warming up to 50~90 DEG C reaction 0.5~5 it is small when, then remove 5~140 parts by weight water, obtain furfuryl alcohol substitute.
As being further improved for above-mentioned technical proposal, the reinforcing agent is silane coupling agent KH602.
As being further improved for above-mentioned technical proposal, the phenols is resorcinol, p-cresol, hydroquinone and waist
One or more combinations of fruit phenol.
As being further improved for above-mentioned technical proposal, the acid is phosphoric acid, sulfuric acid, citric acid and succinic acid one kind or
Multiple combinations.
It is an advantage of the invention that：
Thick liquid is made by reacting using carbohydrate and phenols, formaldehyde using water as solvent, is used to prepare and changes instead of furfuryl alcohol raw material
Property furan resin for casting, reduce manufacturing cost, and maintain original performance, production efficiency is high, reduces secondary pollution.
Specific embodiment

As being further improved for above-mentioned technical proposal, the furfuryl alcohol substitute is made by following steps：By 50 weight
Any combination more than one or both of part six-carbon monosaccharide and disaccharides containing six-carbon monosaccharide structural unit, polysaccharide is dissolved in 15
In~90 parts by weight water, 0.1~26 parts by weight phenols and 5~20 parts by weight acid are then added in, in 60~95 DEG C of temperature conditionss
It is lower reaction 0.5~8 it is small when after, after pH value is adjusted to 7.5~9.5 after being cooled to 25~85 DEG C add in 0.1~15 parts by weight of formaldehyde,
Be warming up to 50~90 DEG C reaction 0.5~5 it is small when, then remove 5~140 parts by weight water, obtain furfuryl alcohol substitute.
