Description
Technical field
The present invention relates to a kind of soluble bonding agent, soluble core model and preparation methods, belong to adhesive techniques field.
Background technique
Composite bend is excellent with its high-strength light, corrosion-resistant, antifatigue, pressure-resistant creep resistant, long service life etc.
Anisotropic energy has become the industries such as aerospace field, ocean development, oil exploitation and smelting, building water supply and drainage, chemical industry urgent need
Product especially in the high-grade, precision and advanced Flight Vehicle Structure of aerospace there is loss of weight to increase journey, improve the important meaning of technique and tactics performance.
However composite bend is typical non-axis symmetry components, with the simple shapes such as straight tube, cone, pressure vessel
The conventional shaping methods such as molding, pultrusion, pipe crimping, injection molding, the winding of axisymmetric body have essential distinction, due to its specification series is more,
Shape and structure is complicated, and it is difficult to prepare.It is past based on production technology is pasted with hand at present for this kind of special-shaped composite bend
Toward the soluble core model using gypsum, but due to lacking briquetting pressure, the appearance of pipe fitting is coarse, intensity is low, performance is dispersed
Greatly, quality is difficult to ensure.
CN201310040115.9 provides a kind of soluble core model using polyvinyl alcohol, quartz sand and water, due to core model
Prepare adhesive with water in production, long time drying needed to core model, production cycle and at high cost, the intensity of core model also compared with
It is low, pressure needed for being not enough to support high-performance composite material structural member molding.
Therefore, it needs to develop a kind of more efficient, higher core model material of intensity in composite bend structure technology of preparing.
Summary of the invention
It is an object of the invention to overcome the shortage of prior art, a kind of more efficient, higher soluble bonding of intensity is provided
Agent, soluble core model and preparation method.
Technical solution of the invention：A kind of solubility bonding agent, based on polyvinyl alcohol resin, in polyvinyl alcohol
The liquid plasticized compound and polyvinyl alcohol resin quality 30~50% of polyvinyl alcohol resin quality 10~30% are added in resin
Solid plasticized compound, the additive amount of liquid plasticized compound will be less than solid plasticized compound；
The liquid plasticized compound is in polyalcohol, such as polyethylene glycol, glycerine, butanediol of low molecular weight etc.
One or more mixing, preferred molecular weight be lower than 1000 liquid polyol；The solid plasticized compound is water solubility
Metal salt or amides compound, such as one of hydrated magnesium chloride, calcium chloride, caprolactam or a variety of mixing, preferably water
Joint compound.
Liquid and solid plasticized compound additive amount are more, and the fusing point of soluble bonding agent is lower, but under its adhesive strength
Drop, specific additive amount can be determined according to the briquetting pressure of receiving required for the core model being prepared.Liquid is plasticized chemical combination
The additive amount of object will be less than the additive amount of solid plasticized compound, and the excessive addition of liquid plasticized compound will increase resin system
Viscosity, cause agglomeration, be unfavorable for adding quartz sand and fiber in subsequent core model preparation process.
In polyvinyl alcohol resin, if only adding liquid plasticized compound, to play and polyvinyl alcohol resin is effectively reduced
Fusing point, additive amount excessively can be unfavorable for subsequent preparation；If only adding solid plasticized compound, polyvinyl alcohol resin is reduced
Fusing point ability it is weaker than liquid plasticized compound, when additive amount is too many, hybrid technique or precipitation may be will affect, the present invention
By adding liquid plasticized compound and solid plasticized compound simultaneously in polyvinyl alcohol resin, polyvinyl alcohol resin is carried out
It is swollen, hydroxyl, metal ion or the amide in polyalcohol are by forming hydrogen bond with polyvinyl alcohol molecule chain, to reduce polyethylene
Active force in alcohol resin between hydroxyl, and then effectively reduce the fusing point of polyvinyl alcohol resin, can avoid it is existing can
Adhesive must be prepared in dissolubility core model technology using water, the defect that core model intensity is not high and the production cycle is long.
A kind of solubility core model, is heated by the soluble bonding agent in core model resin compound and is melted, after cooling and shaping
Solid-state core model is obtained, the core model resin compound includes quartz sand, soluble bonding agent and chopped strand, each component weight
Proportion is 100：(5~20)：(1~3).
Fiber additive amount is more, and core model intensity is accordingly better, but can reduce the craftsmanship of mixing；Soluble bonding agent adds in right amount
Intensity can also be improved by entering, but also will affect hybrid technique too much.The present invention has taken into account craftsmanship and core model intensity, determines optimum ratio.
The soluble bonding agent adds polyvinyl alcohol tree based on polyvinyl alcohol resin in polyvinyl alcohol resin
30~50% solid plasticized compound of liquid plasticized compound and polyvinyl alcohol resin quality of lipid amount 10~30%, liquid increase
The additive amount of modeling compound will be less than solid plasticized compound；
The liquid plasticized compound is the polyalcohol of low molecular weight, such as in polyethylene glycol, glycerine, butanediol
One or more mixing.The solid plasticized compound is water-soluble metal salt or amides compound, should preferentially be selected
It is hydrated one of compound, such as hydrated magnesium chloride, calcium chloride, caprolactam or a variety of mixing.
The fusing setting process is 1~2 hour at 170~200 DEG C.
The quartz sand that the present invention uses routinely uses material to prepare water-soluble core mould, and partial size is generally (50-120)
Mesh.The chopped strand type that the present invention uses there is no limit, can be glass fibre, carbon fiber etc., length be generally (10~
50)mm。
A kind of preparation method of solubility core model, is realized by following steps：
Soluble bonding agent is prepared,
