Abstract
The invention discloses an inorganic composite adhesive for cast exothermic risers, which is characterized by comprising, by weight, 5-9 parts of a yellow dextrin 50% aqueous solution, 90-40 parts of an inorganic high-temperature phosphate adhesive, 1-3 parts of an anti-flame retardant, 0.5-2 parts of a stabilizer, 0.5-1 part of an antioxidant and 0.5-1 part of a reinforcing agent, wherein the raw materials are mixed and then fully and uniformly stirred.
Description
Technical Field
The method is used in the field of industrial casting. Including cast steel, cast iron, non-ferrous metal casting, etc.
Background
In the modern industrial casting field, no matter cast steel, cast iron or nonferrous metal casting, the process is to melt the materials into water at high temperature, then cast the water into a cavity which is made in advance, because the metal has the characteristics of expansion with heat and contraction with cold, in order to accurately cast the required shape, a riser used for feeding in the metal cooling process needs to be designed when a sand mould is designed, the riser has various types, wherein the riser is the best types, the riser can generate heat by itself and improve the feeding efficiency, at the present stage, the production of the riser is formed by bonding powder raw materials in a mould by using an adhesive, the adhesive used on the market at present is mainly phenolic resin, the phenolic resin contains harmful substances such as formaldehyde, phenol and the like, the harmful substances such as very sharp taste are emitted in the production process, the health of workers is harmed, and the environmental protection requirement is not met, types of environment-friendly nontoxic adhesives for replacing the phenolic resin are used, the raw materials do not contain harmful substances such as formaldehyde, phenol and have no pungent smell in the production and use processes, and various indexes such as the bonding strength and the like meet the production requirements.
The invention is not only suitable for the production of the heating riser, but also can be used for molding sand, sand core and other molding materials which can be thermoset. The collapsibility and the bonding strength of the adhesive all meet the production requirements.
Disclosure of Invention
The invention aims to solve the technical problem of providing casting adhesives which have reasonable formula, simple preparation method, environmental protection, high adhesive strength and suitability for .
The technical problem to be solved by the invention is realized by adopting the following technical scheme:
inorganic composite adhesive for casting exothermic risers, which is characterized in that the adhesive is prepared by the following raw materials, by weight, 5-9 parts of yellow dextrin 50% aqueous solution, 90-40 parts of inorganic high-temperature-resistant silicate adhesive, 1-3 parts of flame retardant, 0.5-2 parts of stabilizer, 0.5-1 part of antioxidant and 0.5-1 part of reinforcing agent.
The preferred components of the raw materials are 8 parts of yellow dextrin 50% water solution, 87 parts of inorganic silicate high-temperature adhesive, 1 part of flame retardant, 2 parts of stabilizer, 1 part of antioxidant and 1 part of reinforcing agent.
The adhesive is used for bonding other materials such as sand molds or sand cores, and the components are adjusted according to the requirements of production indexes.
While embodiments of the invention have been described above, it is not limited to the applications set forth in the description and the embodiments, which are fully applicable to various fields of endeavor for which the invention pertains, and further modifications may readily be made thereto by those skilled in the art, it being understood that the invention is not limited to the specific details shown and described herein without departing from the -generic concept defined by the claims and their equivalents.
