Problems solved by technology

Long-term use of over-humidity model is harmful to the model itself, it will cause premature aging of the model and shorten the service life, because when the water content of the model is high, the salt that penetrates into the model will chemically react with dihydrate gypsum reaction
This will cause serious corrosion and damage to the internal structure of the model

Abstract

The invention provides a gypsum mold oil composition. The gypsum mold oil composition comprises 0.2-0.5wt% of lanolin magnesium soap, 3.0-6.0wt% of microcrystalline wax, 3.0-5.0wt% of rosin, 20-30wt% of solvent oil, 0.5-0.6wt% of phthalocyanine blue BGS, and the balance base oil. The gypsum mold oil composition is developed according to the technological characteristics of gypsum molds used in the ceramic production, can satisfy use requirements of molds for ceramic production by like enterprises, and enables the service lives of the gypsum molds to be prolonged by above 20%. The gypsum mold oil composition has the advantages of reasonable compatibility of product raw materials, simple preparation method, wide application range, and easily available raw materials.

Description

technical field [0001] The invention relates to a mold lubricating composition, in particular to a composition used for lubricating plaster molds, and belongs to the field of chemical industry. Background technique [0002] At present, the traditional production process of ceramic wine bottle production enterprises mainly has the following steps: [0003] 1) Beating: The ceramic raw materials configured according to a certain ratio are mixed and crushed, sieved, stirred with water, and precipitated. [0004] 2) Inverting: Introduce the milky raw materials into the mold, and after the rapid water absorption of the gypsum mold, the condensed and formed ones are left as preforms, and the excess is poured out. [0005] 3) Demolding and molding: After several minutes of moisture absorption, it can be demoulded and formed. [0006] 4) Engraving: Carry out bottle mouth repair, and the traces left by the bonding part with the mold should be repaired after drying the preform. [0...
