Abstract

The invention discloses a powdery addition agent for alcohol base cast paint and a preparation and use method thereof. The raw materials of the powdery addition agent comprise the following components, by weight, 4-7% of lithium base bentonite, 59-64% of sodium base bentonite, 4-6% of calcium bentonite, 9-11% of maleated rosin, 2-4% of phenolic resin, 8-10% of low-viscosity polyvinyl butyral, 1-3%of high-viscosity polyvinyl butyral, 2.5-4% of expanded graphite and 0.5-2% of penetrant. According to the powdery addition agent, suspending, bonding and thickening functions are integrated, the addition agent only needs to be mixed with refractory aggregate according to the proportion, the qualified paint can be manufactured through one step, the obtained paint can meet all qualified performance indexes of traditional alcohol base paint, moreover, the use effect is good, the quality of the alcohol base paint is improved, the preparation difficulty of the alcohol base cast paint is reduced greatly, and the unexpected effect is obtained.

Description

technical field [0001] The invention relates to a sand casting coating, in particular to a powdery additive for an alcohol-based casting coating and a method for preparing and using the same. Background technique [0002] At present, in the preparation of alcohol-based casting coatings, it is usually necessary to preform different powder materials, such as resin and bentonite, into liquid states, and then mix different additives and refractory powders in a certain proportion, pre-stirring , and then into a mixing mill or colloid mill or ball mill to prepare a coating. The existing alcohol-based casting coatings have many preparation procedures and types of preparation equipment, which are prone to errors and difficult to guarantee the quality of the coatings. Contents of the invention [0003] The object of the present invention is to provide a powdered auxiliary agent for alcohol-based casting coatings and its preparation and use method. The auxiliary agent improves the ...
