Abstract
The invention relates to a production method of a curing agent and in particular relates to a production method of an alkaline phenolic curing agent for foundry. The production method of the alkaline phenolic curing agent for foundry is characterized by comprising the following steps: firstly starting a stirrer, sequentially adding 2-12% of propylene carbonate, 30-70% of glycerol triacetate, 10-30% of 1,4 butyrolactone and 0-30% of dicarboxylic ester into a reaction kettle, continuing to stir for 30-40 minutes after the addition of the materials is ended, discharging, measuring and packaging, wherein the contents of the raw materials are expressed by weight percent. The production method of the alkaline phenolic curing agent for foundry is unique, capable of effectively avoiding defects of air holes and crazes of steel casting and good in performance of process products.
Description
Technical field
The present invention relates to a kind of production method of curing agent, especially relate to a kind of production method of casting with alkali phenolic curing agent.
Background technology
It is raw material with curing agent employing organic ester that tradition ester solidifies alkalescent phenol resin, and glycerol acetate is main, uses in addition the organosilane esters such as propene carbonate, gamma-butyrolacton, dibasic ester, triacetyl glycerine and does raw-material.The addition of curing agent can not change its setting rate, and can only be by regulating the kind of ester to reach the object that changes setting rate.Domestic from late nineteen eighties start application, start the time of application not very very late, but due to domestic not high to the quality requirement of steel-casting, and the cost of water-glass sand is lower, alkalescent phenol resin sand technique is not well promoted, therefore domestic Steel Castings is used the also fewer of alkalescent phenol resin sand technique, and this is also one of the curing alkalescent phenol resin of ester of domestic production, reason of the general poor quality of curing agent.
Also do not overcome so far the method for above-mentioned defect.
Summary of the invention
The object of the invention is to overcome the defect of prior art, provide a kind of method unique, can effectively prevent steel-casting pore, defects i.e.cracks, the well behaved a kind of production method of casting with alkali phenolic curing agent of handicraft product.
The present invention realizes in the following way:
A kind of production method of casting with alkali phenolic curing agent, it is characterized in that: first the method for starting mixer, successively to adding the propylene carbonate of 2%-12% in reactor, the triacetyl glycerine of 30%-70%, 10%-30% 1,4 butyrolactone and 0%-30% dicarboxylic esters, reinforced complete, continue to stir 30-40 minutes, blowing, metering packing, the content of above-mentioned raw materials is weight percentage;
Described propylene carbonate ester content > 99.9%, triacetyl glycerine ester content > 99%, Isosorbide-5-Nitrae butyrolactone ester content > 99%, dicarboxylic esters ester content is greater than 99%.
The present invention has following effect:
1) method is unique: method provided by the invention is that first the method for starting mixer, successively to adding the propylene carbonate of 2%-12% in reactor, the triacetyl glycerine of 30%-70%, 10%-30% 1,4 butyrolactone and 0%-30% dicarboxylic esters, reinforced complete, continue to stir blowing, metering packing after 30 minutes, the content of above-mentioned raw materials is weight percentage.
2) be the special performance that alkali phenol resin self-hardening sand has: the addition of organic ester curing agent provided by the invention can not change its setting rate, and can only be by regulating the kind of ester to reach the object that changes setting rate.Under organic ester curing agent room temperature, directly carry out glue with alkali phenolic aldehyde and even react, in casting process, the alkali phenolic aldehyde generation polycondensation reaction that glue does not connect, produces rigid net structure, is referred to as post-curing.This plasticity that first shows, then changes into rigidity, produces the sclerosis of elevated temperature strength, is the special performance that alkali phenol resin self-hardening sand has.
3) the present invention investigates by the molding sand experiment catalytic activity to above-mentioned several polynary organic esters, a series of KPE organic ester alkali phenolic curing agents have been developed, be applicable to 5 ℃ of-35 ℃ of sand temperature conditions, casting that the molding sand up time can regulate arbitrarily in 5-40 minutes is used serial organic ester curing agent with alkali phenolic resins is supporting.
4) can effectively prevent that steel-casting pore, defects i.e.cracks, handicraft product are functional: in organic ester curing agent provided by the invention, containing harmful elements such as N, P, S, can effectively prevent steel-casting pore, defects i.e.cracks.No matter on handicraft product Mou Foundry Works steel-casting, use, be molding sand smell, or molding sand up time, intensity, all can meet on-the-spot instructions for use, and handicraft product is functional.
