Изобретение относитс к составам поливинилацетатных клеев, примен емых дл склеивани составных литейных стержней.This invention relates to compositions of polyvinyl acetate adhesives used for bonding composite casting cores.
Известен клей, включающий поливинилацетатную эмульсию, воду и минеральный наполнитель .Known adhesive, including polyvinyl acetate emulsion, water and mineral filler.
Цель изобретени - увеличение прочности склеенных литейных стержней и их газопроницаемости .The purpose of the invention is to increase the strength of glued casting cores and their gas permeability.
Это достигаетс тем, что в качестве наполнител предлагаемого кле применен феррохромный шлак при следующем соотношении ингредиентов, вес. %:This is achieved by using ferrochromic slag as the filler of the proposed adhesive in the following ratio of ingredients, weight. %:
Поливинил ацетатна эмульси 50%-на 30-40Polyvinyl acetate emulsion 50% on 30-40
Вода20-40Water 20-40
Феррохромный шлак30-40Ferrochrome slag 30-40
В табл. 1 приведены составы клеев с известными и предлагаемыми наполнител ми.In tab. Table 1 lists the compositions of adhesives with known and proposed fillers.
