Abstract

The invention relates to a bonding agent used for magnesia carbon-containing refractory materials , which consists of materials with weight proportions as follows: 100 proportions of phenolic resin; aromatic polyester and coal tar pitch with the weight accounting for 15-30% of the weight of the phenolic resin or polyamide resin; coal tar distillation anthracene oil product with the weight accounting for 50-60% of the weight of the coal tar pitch; and solvent with the weight accounting for 17-32% of the weight sum of the four materials. The beneficial effects are as follows: a series of products of the bonding agent used for the magnesia carbon-containing refractory materials are provided, and the production cost is reduced greatly, thus having obvious economic and social benefits. The product quality is stable and reliable, the performance of the bonding agent meets the standard of the existing bonding agent by inspection, and solid content and residual carbon amount are significantly higher than the existing bonding agent of the refractory materials, thus leading the performance indicators of the refractory materials to be improved.

Description

technical field

[0001] The invention relates to a binder used in the refractory industry, in particular to a binder for magnesia carbon-containing refractory materials, referred to as LFQ binder. Background technique

[0002] At present, the existing domestic refractory binders generally use thermoplastic or thermosetting phenolic resins. Manufacturers generally report that their production costs are high, the variety is single, and the quality is not ideal enough to meet the needs of the production of magnesia carbon-containing refractory materials. Therefore, research It is imperative to develop new binders for magnesia carbon-containing refractories. Contents of the invention

[0003] The purpose of the present invention is to provide a binder for magnesia carbon-containing refractories, which greatly reduces production costs, greatly improves product quality, and has stable quality, which can meet the production requirements of magnesia carbon-containing refractories. ...
