Abstract

The present invention discloses a formula, synthesis and application of amide-type polyether sodium sulfonate macromolecules. A small amount of the product is added into beta gypsum to replace the conventionally used mixed alpha and beta gypsum to produce a gypsum mould . Even at a high water-gypsum ratio, the strength of the mould gypsum can be improved while the demand on water absorption of the gypsum mould is ensured, so that the cost of gypsum raw materials is lowered, and the number of use of the gypsum mould is improved.

Description

【Technical field】

[0001] The invention relates to the synthesis and application of an amide polyether sodium sulfonate macromolecule used for mold gypsum reinforcement, and belongs to the field of material technology. 【Background technique】

[0002] Gypsum is widely used in ceramics and other industries due to its advantages such as abundant raw materials, low production cost, environmental protection, and good plasticity. However, when preparing gypsum molds, the actual water consumption is far greater than the theoretical hydration water demand, resulting in the fatal weakness of low strength, easy damage, poor quality, and short service life of gypsum molds. With the gradual development of the ceramic industry in the direction of mechanized and automated production, the domestic demand for plaster molds is increasing, and the quality requirements are also higher. Compared with the method of mixing high-priced and high-quality α-hemihydrate gypsum and cheap and inferior β...
