Abstract
The invention relates to the field of casting, in particular to a sudden-heating-resistant casting coating. The sudden-heating-resistant casting coating is characterized by comprising, by weight, 30-40 parts of modified polyurethane copolymer, 10-15 parts of methylbenzene, 5-10 parts of acrylic ester, 1-3 parts of a flatting agent, 2-3 parts of a hand feeling agent, 40-50 parts of ethyl acetate, 1-3 parts of a defoaming agent, 1-2 parts of a levelling agent, 6-9 parts of pentaerythritol, 2-4 parts of ammonium polyphosphate, 2-3 parts of activated calcium carbonate and 2-4 parts of calcium chloride. The sudden-heating-resistant casting coating has incombustibility and a low heat conduction coefficient, is not prone to cracking or stripping when encountering a high temperature, and has quite high sudden heating resistance.
Description
Technical field:
The present invention relates to casting field, relate to a kind of emergency heat and cooling property resistance cast paint in particular.
Background technology:
The coating of sand casting, mainly for shielding the interphase interaction of sand mold and metal liquid, density fireproof coating is formed under cast temperature, placing metal liquid penetrates in sand mold, simultaneously because the material of sand mold at high temperature decomposes generation gas, coating can prevent from entering in metal liquid, affects the surface smoothness of foundry goods.Conventional is cold coating at present, because be suspension liquid, and suspension is low, do not stop during use to stir and could brush evenly, otherwise fine and close coating can not be formed, when pouring into the alloy solution of melting, meeting instantaneous touch high temperature, has cracking to a certain degree and stripping.
Summary of the invention:
Technical problem to be solved by this invention is that overcoming existing technological deficiency provides a kind of emergency heat and cooling property resistance cast paint.
Technical problem to be solved by this invention adopts following technical scheme to realize:
A kind of emergency heat and cooling property resistance cast paint, is characterized in that the component comprising following weight portion: 30-40 part modified polyurethane copolymer, 10-15 part toluene, 5-10 part acrylate, 1-3 part delustering agent, 2-3 part hand feeling agent, 40-50 part ethyl acetate, 1-3 part defoamer, 1-2 part levelling agent, 6-9 part pentaerythrite, 2-4 part APP, 2-3 part activated Calcium carbonate, 2-4 part calcium chloride.
Further, described modified polyurethane copolymer comprises the component of following weight portion: 5-10 part terephthalic acid (TPA), 10-12 part ethylene glycol, 40-50 part polyurethane copolymer, 2-4 part PAG, 5-10 part hydrochloric acid, 2-3 part silica, 1-3 part stearate, 2-4 part kaolin.
Further, the preparation method of described modified polyurethane copolymer is: terephthalic acid (TPA), ethylene glycol, PAG are put into reactor and carried out condensation reaction, then hydrochloric acid is put into, adjustment PH is 5-6, then add silica successively, stearate, kaolin stirs, omnidistance temperature controls at 110-130 DEG C, evenly rear cooling discharging to be mixed.
A preparation method for emergency heat and cooling property resistance cast paint, is characterized in that comprising the following steps:
(1) by modified polyurethane copolymer, toluene and portion of ethyl acetate Homogeneous phase mixing;
(2) acrylate, activated Calcium carbonate, calcium chloride are mixed with another part ethyl acetate homogeneous heating, heating-up temperature is 30-40 DEG C;
(3) mixture mixing step (1) and (2) obtained, adds remaining raw material Homogeneous phase mixing in mixed process.
The present invention itself has noninflammability, has lower thermal conductivity factor, then when running into high temperature, stripping not easy to crack, has good emergency heat and cooling property resistance.
