Известна противопригарна  краска дл  покрыти  поверхности форм из твердеющих смесей и сырых форм и стержней из песчаноглинистых смесей при чугунном и цветном литье. Известны противопригарные краски дл  литейиых форм, в состав которых вход т графит и растворитель.A known nonstick paint for coating the surface of molds of hardening mixtures and raw molds and cores of sand-clay mixtures in iron and non-ferrous castings. Non-stick paints for casting molds are known, which include graphite and solvent.

Предлагаема  краска в отличие от известных содержит, кроме графита и растворител , еще и поливинилбутираль, что позвол ет получать устойчивый коллоидный раствор любой консистенции. Краска длительное времс  не расслаиваетс , хорощо покрывает поверхности форм и стержней и обладает необходимым и противопригарными свойствамиThe proposed paint, in contrast to the known ones, contains, in addition to graphite and solvent, also polyvinyl butyral, which makes it possible to obtain a stable colloidal solution of any consistency. The paint does not peel off for a long time, well covers the surfaces of the molds and cores and possesses the necessary and nonstick properties

Краска содержит 30% аморфного графита и 3-4% поливинилбутирал ; растворитель добавл етс  до получени  удельного веса 1 08-1 1 В качестве растворител  может использоватьс  технический спирт или отходы химической промыщленности (смесь спирта со сложными эсЬирами , например этилацетатом).The paint contains 30% amorphous graphite and 3-4% polyvinyl butyral; The solvent is added until the specific gravity is obtained. 1 08-1 1 As a solvent, technical alcohol or chemical waste can be used (a mixture of alcohol with complex esters, such as ethyl acetate).

Краска наноситс  на поверхность форм и стержней из химически твердеющих смесей, а также на поверхность сырых форм и стержней из песчаноглинистых смесей. Нанесенна  на поверхнос форм Гст ржней краска высыхает в течение 10-12 мин при комнатной температуре При применении краски дл  форм цветного лить  вместо графита в краску ввод т тальк.рлфи)с1The paint is applied to the surface of molds and rods from chemically hardening mixtures, as well as to the surface of raw molds and rods from sand-clay mixtures. The paint applied to the surface of the HGT forms dries out within 10-12 minutes at room temperature. When using paint for color casting forms instead of graphite, paint is added to the paint.

Описываема  краска внедрена в производство на невском металлургическом заводе им. Ленина (г. Ленинград). Эта краска позволила повь1 ГобтДнкТ товарный вид лить , снизить брак и затраты на обрубные работы, улучшить поверхность лить  и сократить цикл изчастГпи к/ Г - описанной краски позволило перевести твердеющих смеГ применением химическиThe described paint is introduced into production at the Neva Metallurgical Plant named. Lenin (Leningrad). This paint made it possible to put GobtDnKT trade dressing, reduce scrap and cutting costs, improve the surface of the cast and shorten the cycle of parts of the c / L - the described paint allowed to translate hardening materials using chemically

№ 14887g-2Предмет изобретени № 14887g-2 of the invention

Противопригарна  краска дл  покрыти  поверхности форм из твердеющих смесей и сырых форм и стержней из песчаноглииистых смесей при чугунном и цветном литье, отличающа с  тем, что, с целью устранени  расслоени  покрыти , краску приготовл ют на основе перспективного материала - поливинилбутирал , растворител  и наполнител , котора   вл етс  безводной, быстровысыхающей, устойчивой и обеспечивающей чистоту поверхности лить .A non-stick paint for coating the surface of hardening mixtures and raw forms and rods of sand-glue mixtures in cast-iron and non-ferrous castings, characterized in that, in order to eliminate delamination of the coating, the paint is prepared on the basis of a promising material - polyvinyl butyl, solvent and filler, which is anhydrous, fast-drying, stable and ensuring a clean casting surface.
