Abstract
The invention relates to the technical field of binding agent production, in particular to a full mold binding agent and a preparation method thereof. The full mold binding agent is characterized by being prepared from, by weight, 60-80 parts of polyvinyl acetate emulsion, 10-16 parts of polybutadiene, 5-10 parts of ethenyl ethanoate, 5-8 parts of bone glue, 10-18 parts of paraffin, 3-5 parts of maleic anhydride and 2-6 parts of dimethylethanolamine. The bone glue and the paraffin are firstly ground, then the paraffin, the bone glue, the polyvinyl acetate emulsion, polybutadiene, ethenyl ethanoate, maleic anhydride and dimethylethanolamine are fully mixed and heated to 60 DEG C to 70 DEG C, and then cooling and packaging are carried out. In the full mold workpiece casting process, the binding agent is high in binding performance, small in pollution, low in boiling point and free of residues.
Description
Technical field:
The present invention relates to adhesive production technical field, specifically a kind of evaporative pattern binding agent and preparation method thereof.
Background technology:
Lost foam casting is that foam mould adopts bindless dry sand in conjunction with the cavityless casting of vacuum pumping technology.Domestic main call has " dry sand cavityless casting ", " vacuum full mold casting ", is called for short EPC casting.Lost foam casting is current one of state-of-the-art casting technique in the world, is described as once " revolution " in casting history, is referred to as 21 century Green foundry both at home and abroad.Not much that overall time is shaping in the prior art of evaporative pattern, need just can be completed by bonding moulding, and there is coating outside, binding agent for evaporative pattern bonding of the prior art is fairly simple, some boiling point is high, is unfavorable for casting, easily leaves some residues after evaporation, metalwork for casting has a certain impact, and stickiness is not high.
Summary of the invention:
It is high that technical problem to be solved by this invention is to provide a kind of caking property, and pollute little, boiling point is low, without the evaporative pattern binding agent and preparation method thereof of residue.
Solve technical problem adopt following technical scheme:
A kind of evaporative pattern binding agent, is characterized in that: be made up of following parts by weight of component,
Be made up of following parts by weight of component,
A kind of preparation method of evaporative pattern binding agent, described adhesive is made up of following methods, first by gelatine and paraffin abrasive dust, again paraffin, gelatine are fully mixed with polyvinyl acetate emulsion, polybutadiene, vinyl acetate, maleic anhydride and dimethylethanolamine, be heated to 60 ~ 70 DEG C, then cooling packing.
Described adhesive in use heating temperatures to 60 ~ 70 DEG C.
The binding agent used in the present invention has and has good viscosity, be not easy cracking, and binding agent becomes pasty state after bonding, and inner homogeneous without slag, and is at high temperature easy to evaporation disappearance, and at high temperature noresidue residue generates, due to the casting of workpiece.Maleic anhydride in the present invention has the effect increasing binding agent viscosity, and can increase the uniformity of binding agent.
The preparation method of the binding agent in the present invention can make binding agent evenly, binding agent of the present invention by heating temperatures 60 ~ 70 DEG C, has better bond effect in use.
The invention has the beneficial effects as follows: evaporative pattern of the present invention is when workpiece is cast, and the caking property of binding agent is high, and pollute little, boiling point is low, without residue.
Detailed description of the invention:
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with instantiation, setting forth the present invention further.
