Abstract
The invention discloses a mending agent for a full mold processed foam model. The mending agent is mainly composed of EPS foam powder, a binding agent and water which are mixed, and then are uniformly stirred so as to form paste. Compared with the prior art, the mending agent, formed by the EPS foam powder, the binding agent and the water which are mixed into the paste, has the advantages of being not easy to dissolve, being directly coated in a seam and a breakage part of the foam model, being convenient to operate, and improving the production efficiency.
Description
Technical field
The present invention relates to a kind of cavityless casting bubbles model healant.
Background technology
At present, in the cavityless casting process, use EPS(polystyrene) foam is as the running gate system in the casting process, produce bubbles model by eps foam, coat fireproof coating at bubbles model then, after the drying, bubbles model is imbedded in the molding sand, foam is gasificated into the gas discharge in the pouring molten iron process, and molten iron fills type and forms the foundry goods overall size.
After bubbles model completes, because the characteristic of foam is damaged easily, breakage for large-area breakage, can be repaired by bonding foam, but the breakage for small size, use foam to repair and be difficult to carry out, and the modelling process is to need splicing, so just have the problem of seam, be to use old and useless newspaper abutment joint place to handle or use bright and clean coating for this problem at present, in these two kinds of methods, adopt the newspaper processing time longer, not easy to operate; Use bright and clean coating, because paraffin chance high temperature can melt in the bright and clean coating, oven dry after the model showering is coated, the bright and clean coating fusing of paraffinic base is that dope layer peels off, and influences coating quality.
Summary of the invention
Technical problem to be solved by this invention provides a kind of cavityless casting bubbles model healant, to be used for the repairing to bubbles model seam and small size breakage.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of cavityless casting bubbles model healant, mainly constituted by eps foam powder, adhesive and water mixing, and after mixing, be stirred into paste.
The volume ratio of described eps foam powder, adhesive and water is 1:(1.2 ~ 1.3): (0.1 ~ 0.2).
Healant also comprises industrial alcohol, and the volume ratio of described eps foam powder, adhesive, water and industrial alcohol is 1:(1.2 ~ 1.3): (0.1 ~ 0.2): (0.15 ~ 0.25).
Described adhesive adopts white glue with vinyl.
The present invention adopts technique scheme, compared with prior art, eps foam powder, adhesive and water are mixed into paste, healant as the cavityless casting bubbles model, has not diffluent advantage, directly healant is coated in seam and the breakage of bubbles model during use, easy to operate, improved production efficiency.
The specific embodiment
Do detailed explanation below in conjunction with the present invention of embodiment.
A kind of cavityless casting bubbles model of the present invention healant mainly is made of eps foam powder, adhesive and water mixing.In the process for preparation, in the eps foam powder, add a certain amount of adhesive earlier, add suitable quantity of water afterwards and dilute, and be stirred into paste.In use, can directly the healant of paste be coated in the seam crossing of bubbles model, the breakage of the small size on bubbles model also can directly be coated the healant of paste, and is smooth to repair.
The volume ratio of eps foam powder, adhesive and water is 1:(1.2 ~ 1.3): (0.1 ~ 0.2).
Adhesive of the present invention is that the model that Wuhu city bright latex factory produces is the white glue with vinyl of WG-200.
Eps foam powder degree of the present invention is 100 orders, and softening temperature is 60 ~ 65 ℃.
Because white glue with vinyl is water miscible, meet water and easily dissolve, so need mix with the eps foam powder, the eps foam powder can be played a supporting role, and is equivalent to support frame.If again owing to only add white glue with vinyl words, white glue with vinyl and the mixed viscosity of eps foam powder, are diluted so also need to add an amount of water than higher, reduce viscosity, otherwise can cause being not easy floating putting in order owing to white glue with vinyl is too sticking when repairing.
Can also add appropriate amount of industrial alcohol at healant, the volume ratio of eps foam powder, adhesive, water and industrial alcohol is 1:(1.2 ~ 1.3): (0.1 ~ 0.2): (0.15 ~ 0.25).
Ethanol content is more than or equal to 95% in the industrial alcohol, and methanol content is lower than 0.01%
Do not add the healant of industrial alcohol can be in the operation of bubbles model surface showering refractory material bubbles model occur using when damaged.But when sand is buried in moulding, under the situation of processing industry alcohol not, be coated in and make cast iron produce pore easily after moisture in the healant on the bubbles model runs into high temperature liquid iron, so need in healant, add industrial alcohol, just can reduce the ratio of the water in the adding healant accordingly.Because industrial alcohol itself moisture few (at most moisture 5%), add industrial alcohol after, total corresponding minimizing of moisture in the healant has also just reduced the probability of cast iron generation pore when sand is buried in moulding.
