Abstract

The invention discloses an inorganic adhesive, as well as preparation and application methods thereof. The inorganic adhesive is prepared from the following materials in parts by mass: 100 parts of water glass, 1 to 15 parts of phosphoric acid, 0.2 to 5 parts of sodium aluminate, 1 to 5 parts of polymeric borate-sodium, and 3 to 5 parts of potassium trimethylsilanolate. The invention further discloses the preparation method of the inorganic adhesive. The preparation method comprises the steps of mixing, heating and stirring the components so as to form a colorless, tasteless, non-combustible and transparent resin. The inorganic adhesive prepared through the invention is mainly applied to the casting industry so as to replace an alkaline phenolic resin and a furan resin, and the problem that an organic resin produces pungent smells and dioxin during the casting process is solved. The inorganic adhesive provided by the invention is low in inorganic resin adding amount, high in strength,good in collapsibility, good in withdrawing capability, beneficial to reducing the casting cost, and tasteless and non-toxic at the same time; and the non-combustible water-based inorganic resin is agreen and environmental-friendly product.

Description

technical field [0001] The invention relates to an inorganic adhesive and its preparation and application methods, belonging to the technical field of material modification. Background technique [0002] The organic resin binder in the foundry industry is generally alkali phenolic resin or furan resin, which produces irritating odor and dioxin problems during the casting process; ordinary water glass and modified water glass are added in a large amount when making sand molds during casting , At the same time, there is the problem of poor sand mold collapse. Contents of the invention [0003] In order to solve the problems existing in the prior art, the object of the present invention is to provide a safe, environmentally friendly inorganic adhesive that can effectively improve the collapsibility of sand molds during casting, as well as its preparation and application methods. [0004] The technical solution of the present invention is: an inorganic adhesive, comprising th...
