Abstract

The invention relates to fire-resistant quartz powder mending paste. The fire-resistant quartz powder mending paste consists of the following components in part by weight: 70 to 80 parts of quartz powder, 5 to 15 parts of diatomite, 2 to 6 parts of sodium carboxymethylcellulose, 2 to 4 parts of polyvinyl alcohol mixture, 20 to 40 parts of fire-resistant particles and the balance of water, whereinthe fire-resistant particles consist of the following components in part by weight: 20 to 40 parts of aluminium silicate firefibre, 50 to 70 parts of quartz powder and 10 to 30 parts of magnesia powder; and the polyvinyl alcohol mixture is colloidal solution and consists of the following components in part by weight: 10 to 20 parts of polyvinyl alcohol, 2 to 6 parts of acetic acid, 2 to 6 parts of polypropylene and 100 parts of water. The fire-resistant quartz powder mending paste has the advantages of simple components, simple and easy preparation operation, lower production cost, higher fire resistance, higher toughness and easy uniform mixing.

Description

technical field [0001] The invention relates to a paint, in particular to a refractory quartz powder repair paste, which is particularly suitable for repairing the inner and outer surfaces of sand molds for casting. Background technique [0002] With the rapid development of the foundry industry, the requirements for the surface quality of casting workpieces are getting higher and higher, and the requirements for sand surface coatings are also increased. Generally, uniform quality, excellent adhesion, strong water and heat resistance must be required, and It is stable at room temperature and high pressure, easy to paint, and can prevent defects such as sand sticking and sand inclusion during casting, so as to obtain castings with smooth surfaces. [0003] The Chinese patent publication number is CN1082466A, and the invention patent disclosed on February 23, 1994 discloses a refractory powder with graphite powder, zircon powder, high alumina powder, titanium slag powder, bent...
