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
The present invention relates to the wedding agent that fire-resistant industry is used, particularly a kind of binder for magnesium carbonaceous fire-resistant material is called for short LFQ type wedding agent.
Background technology
At present, domestic existing binder for fire-resistant materials, general thermoplasticity or the heat-reactive phenolic resin of adopting, producer reflects that generally its production cost is higher, and kind is single, and quality is not ideal enough, can not satisfy the needs that carbonic refractory material in magnesium texture is produced, so, research and development magnesial binding agent for carbonic refractory material, imperative.
Summary of the invention
The purpose of this invention is to provide a kind of binder for magnesium carbonaceous fire-resistant material, this wedding agent greatly reduces production cost, has improved quality product greatly, and steady quality, can satisfy the production requirement of carbonic refractory material in magnesium texture.
For achieving the above object, technical scheme of the present invention is described below:
A kind of binder for magnesium carbonaceous fire-resistant material, it by following material by weight ratio form:
100 parts of resol or aromatic polyesters;
Coal-tar pitch, its weight are 15～30% of resol or polyamide weight;
The anthracene oil product of coal tar distillation, its weight are the 50-60% of coal-tar pitch;
Solvent be above-mentioned weight and 17-32%.
Preferably, coal-tar pitch, its weight is 30% of resol or polyamide weight.
Described coal-tar pitch is meant the special asphalt of β resin content 〉=30% and remaining carbon 〉=60%.
Described solvent is meant one or more mixing in alcohols, ester class, benzene class or the tarry cut.
The manufacture method of described binder for magnesium carbonaceous fire-resistant material is: phenol and formaldehyde are after the catalysis polycondensation finishes, add coal-tar pitch and carbolineum Yong ≧ heating of 0.4MPa air pressure and stirring, time was controlled at more than 60 minutes, vacuumize then and thermal dehydration, make moisture reach＜7%, after moisture is qualified, use solvent adjustment viscosity again, viscosity is controlled at 1-30PaS according to user's requirement.
Compared with prior art, the invention has the beneficial effects as follows: a kind of series product of binder for magnesium carbonaceous fire-resistant material are provided, and production cost reduces significantly, and tangible economic benefit and social benefit are arranged.Quality product is improved, and steady quality is reliable, and by check, the performance index of this wedding agent have reached the standard of existing national metallurgy industry wedding agent.
