Abstract
The invention relates to a magnesia refractory material binder and a preparation method thereof. The magnesia refractory material binder comprises 40-70wt% of phenolic resin, 10-30wt% of aromatic polyester, 5-25wt% of a solvent and 5-25wt% of a reinforcing agent. The preparation method greatly reduces the production cost, and has obvious economic and social benefits. The binder has stable and reliable quality; and an examination result shows that the performance indexes of the binder reach standards of present binders, and the solid content and the carbon residue are obviously higher than those of present refractory material binders, so the performance indexes of refractory materials are improved.
Description
Technical field
The present invention relates to technical field of refractory materials, particularly relate to a kind of binder for making magnesia refractory and preparation method thereof.
Background technology
At present, domestic existing binder for fire-resistant materials, general employing thermoplasticity or heat-reactive phenolic resin, producer generally reflects that its production cost is higher, and due to bonding agent kind single, the different needs that high, medium and low magnesite refractory is produced can not be met, all adopt high-grade thermoplasticity or heat-reactive phenolic resin bonding agent at present, expensive, so, research and develop the magnesite refractory bonding agent of different class, imperative.
Summary of the invention
The object of this invention is to provide the series product of binder for magnesium carbonaceous fire-resistant material, greatly reduce production cost, and be divided into high, medium and low, can according to carbonic refractory material in magnesium texture need select, its constant product quality, can meet 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 making magnesia refractory and preparation method thereof, is made up of by weight proportion following material:
Resol 40-70%
Fragrance aromatic polyester 10-30%
Solvent 5-25%
Toughener 5-25%.
Described manufacture method is: phenol and formaldehyde are after catalyzed polycondensation reaction terminates, form resol, then add aromatic polyester to carry out heating, stir, dewater, moisture is made to reach less than 10%, after moisture is qualified, use solvent adjustment viscosity again, viscosity controls at 1-30PaS according to the requirement of user.
Described solvent refers to one or more mixing in alcohols, ester class, benzene class or tarry cut, and described toughener is tetramethylolmethane.
Compared with prior art, the invention has the beneficial effects as follows: the series product providing binder for magnesium carbonaceous fire-resistant material, production cost significantly reduces, and has obvious economic benefit and social benefit.Stable and reliable product quality, by inspection, the performance index of this bonding agent reach the standard of now educating bonding agent, and solids content and remaining carbon are apparently higher than existing binder for fire-resistant materials, and the performance index of refractory materials are also increased.
