High air temperature adaptive plastic stuffing for crusher

Abstract

The invention belongs to the chemical engineering technical field, relating to a high temperature adaptive plastic property preparation liner used in a crusher. The plastic property preparation liner is characterized in that: in the bi-component formulation of the plastic property preparation liner, the mixed solvent of the resin is changed as follows: three or more than three of combinations of glycol, diethylene glycol, cyclohexanone, butyl cellosolve, dibutyl phthalate, n-Amyl acetate and butyl acetate are selected as the mixed solvent; the resin solution is a stable viscous fluid preparedby well blending epoxy resin, mixed solvent, intensifier, and toughener according to the fixed mixture ratio and forms a plastic filler with a firming agent system. The high temperature adaptive plastic property preparation liner used in a crusher can be applied in the maintenance of the lining board of the crusher in the temperature of 35 DEG C, does not generate hard bubbles, meets and guarantees the requirements of the replacement and maintenance of the crusher in summer.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and relates to a multi-component resin cast body, which is used as a liner plate of a crusher in mining and mineral processing production, and in particular to a plastic filler for a crusher suitable for high temperature. Background technique [0002] At present, in the domestic crushing operation of mining and mineral processing, in order to closely combine the fixed cone and the support and between the movable cone and the cone of the crusher, it is necessary to pour the lining. The main forms are: one is to pour cement into the cavity, A mixture of inorganic binder and water; before pouring, mix it evenly and pour it in by itself, and use it after it is strong; the second is lead-zinc alloy pouring; first melt the alloy with a heating furnace and a crucible, and use it within the operable time The rod guides the molten alloy into the cavity; the third is the pouring of the plastic fi...

Problems solved by technology

[0004] The present invention overcomes the above-mentioned defects, and aims to solve the problem that under high temperature conditions in summer, the foaming of the plastic backing makes the pouring body appear hard and foamy, which endangers the use of the crusher, and provides a kind of plastic lining for the crusher that is suitable for high temperature. filler
