Problems solved by technology

[0003] In the foundry industry, foundry sand matching plays a very important role in the casting quality of castings. However, traditional foundry sand matching auxiliary materials can no longer meet the quality requirements of castings, such as fat oil and tung oil. During the casting process, it is easy to produce air voids and Insurmountable defects such as subcutaneous air and air, and the other two are liquids that are not conducive to transportation and storage, and have a pungent smell, which makes people easy to breathe, which is not conducive to health and work. For this reason, people have been seeking an ideal technical solutions

Abstract

A flanged casting box filler for sand replacement and a preparation method thereof, comprising the following components: 100-200 parts of purple sand mineral material, 180-220 parts of modified starch, 80-120 parts of metal pulp waste, and 150‑160 parts of ionized water, 1‑2 parts of emulsifier, 3‑14 parts of acrylic acid, 2‑3 parts of methacrylic acid, 3‑5 parts of chain transfer agent, 1‑3 parts of initiator, 10 parts of acidic or alkaline aqueous solution 15 parts, metal particles 100‑120 parts. Moreover, the castings produced by using this filler can improve the hot-wet tensile strength, air permeability, fluidity, and toughness of the sand mold, and can improve the release property of the sand mold, reduce the sensitivity to moisture during pouring, and at the same time, there is no risk of casting Defects such as sticky sand, sand inclusions, sand washing, pores, etc.

Description

Technical field: [0001] The invention relates to the field of mold manufacturing, in particular to a filler for a flange casting box replacing sand and a preparation method thereof. Background technique: [0002] Flange is also called flange flange or flange. Flanges are parts that are connected to each other between pipes and are used for connection between pipe ends; they are also useful for flanges on equipment inlets and outlets, And can be used as connection between two equipments, example reducer flanges. Flange connection or flange joint refers back to the detachable connection of flange, Gasket and bolt as a team of combined sealing structure. Pipe flange refers back to the flange used for piping in the pipeline installation, And used on the equipment refers to the inlet and outlet flange of the equipment. There are holes in the flange, and the bolts tightly connect the two flanges. The flanges are sealed with gaskets. Flanges are divided into threaded (screw con...
