Problems solved by technology

[0002] At present, the existing domestic refractory binders generally use thermoplastic or thermosetting phenolic resins. Manufacturers generally report that their production costs are relatively high, and because of the single variety of binders, they cannot meet the different needs of high, medium and low-grade magnesia refractory production. At present, high-grade thermoplastic or thermosetting phenolic resin binders are used, which are expensive. Therefore, it is imperative to research and develop different grades of binders for magnesia carbon-containing refractories.

Embodiment 1

[0025] A binder for magnesia carbon-containing refractories, which consists of the following materials in proportion by weight:

[0026] 100 parts of phenolic resin;

[0027] Aromatic polyester, 30-60% by weight of phenolic resin;

[0028] The solvent is 17-32% of the above weight sum.

[0029] The aromatic polyester refers to or one or a combination of both.

[0030] The solvent refers to one or a mixture of two or more of alcohols, esters, benzenes or tar fractions.

[0031] The manufacturing method of the binder for magnesia carbon-containing refractories is: after the catalyzed polycondensation reaction of phenol and formaldehyde is completed, a phenolic resin is formed, and then an aromatic polyester is added for heating, stirring, and dehydration, so that the moisture reaches <7% ( It can also be used according to the user's requirements (<11%). When the water content is qualified, the viscosity can be adjusted with a solvent, and the viscosity can be controlled ...

Embodiment 2

[0033] The binder for magnesia carbon-containing refractory materials can also be composed of the following materials in proportion by weight:

[0034] 100 parts of phenolic resin or aromatic polyester;

[0035] Coal tar pitch, 30% by weight of phenolic resin or aromatic polyester;

[0036] Anthracene oil product from coal tar distillation, 50-60% by weight of coal tar pitch;

[0037] The solvent is 17-32% of the above weight sum.

[0038] The aromatic polyester refers to or one or a combination of both.

[0039] The solvent refers to one or a mixture of two or more of alcohols, esters, benzenes or tar fractions.

[0040] The manufacturing method of the binder for magnesia carbon-containing refractories is as follows: after the catalyzed polycondensation reaction of phenol and formaldehyde is completed, or after the aromatic polyester is heated and melted, coal tar pitch and anthracene oil are added, heated and Stirring, the time is controlled at more than 60 minutes,...

Embodiment 3

[0042] The binder for magnesia carbon-containing refractory materials can also be composed of the following materials in proportion by weight:

[0043] 100 parts of aromatic polyester;

[0044] The reinforcing agent is 8% of the weight of the aromatic polyester; the reinforcing agent is pentaerythritol.

[0045] The solvent is 17-32% of the above weight sum.

[0046] The manufacturing method of the binder for magnesia carbon-containing refractory materials is as follows: after the aromatic polyester is heated and melted, a reinforcing agent is added, and then a solvent is used to adjust the viscosity, and the viscosity is controlled at 1-30 Pa·S according to the user's requirements.

[0047] The aromatic polyester refers to or one or a combination of both.

[0048] The solvent refers to one or a mixture of two or more of alcohols, esters, benzenes or tar fractions.

[0049] The binder of the present invention has been trial-produced in Jinan Quansheng Refractory Co., L...

Abstract

This invention relates to a bonding agent for magnesium-based carbon-containing refractory material. The bonding agent is composed of: phenol formaldehyde resin 100 parts, aromatic polyester 30-60 parts, and solvent 17-32 wt. % of phenol formaldehyde resin and aromatic polyester. The bonding agent has such advantages as stable quality, high solid content and high carbon residue content, and can improve the properties of the refractory material.

Description

technical field [0001] The invention relates to a binding agent used in the refractory industry, in particular to a binding agent for magnesia carbon-containing refractory materials. 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 relatively high, and because of the single variety of binders, they cannot meet the different needs of high, medium and low-grade magnesia refractory production. At present, high-grade thermoplastic or thermosetting phenolic resin binders are used, which are expensive. Therefore, it is imperative to research and develop different grades of binders for magnesia carbon-containing refractories. Contents of the invention [0003] The purpose of the present invention is to provide a series of binders for magnesia carbon-containing refractory mater...
