Room-temperature-cured epoxy resin cast cushion block and preparation method thereof

Abstract

The invention belongs to a filling material used for fixing equipments, and especially relates to a room-temperature-cured epoxy resin cast cushion block and a preparation method thereof. According to existing technologies, the fixation of machineries with relatively large weights requires a large amount of bolts, such that the operation is difficult; in an environment with severe corrosion, fixing bolts are likely to be corroded, and the strengths of the bolts are reduced. The a room-temperature-cured epoxy resin cast cushion block provided by the invention is composed of, by weight: 100 parts of epoxy resin, 0 to 20 parts of a toughening agent, 0 to 3 parts of a diluent, 50 to 100 parts of active silicon micro-powder, 5 to 25 parts of an active crystal whisker material, 0 to 3 parts of titanium dioxide, 0 to 3 parts of a pigment, 0 to 1 part of an antifoaming agent, and 5 to 15 parts of a curing agent. The invention is advantaged in that: the surface properties of the product provided by the invention are stable, the product is not easy to contract, and the service life of the product is long. The cushion block can be cured under room temperature, such that the preparation method is simple. With the cushion block, the equipment can be firmly fixed, and requirements under vessel rocking and corrosion conditions can be satisfied.

Description

technical field [0001] The invention belongs to equipment fixing filling materials, in particular to a room temperature curing epoxy resin pouring pad and a preparation method thereof. technical background [0002] Important mechanical equipment in a factory or on a ship needs to be fixed. The traditional method is to use bolts to fix the equipment to the base. The disadvantages of this method are: 1. The effect of bolts to fix small mechanical equipment is good, but a lot of bolts are needed to fix larger weight mechanical equipment, which is difficult to operate; It is corroded, the strength is reduced, and there is a danger of sliding when the ship shakes. Especially the main propeller of the ship has strict positioning requirements, is heavy, and the environment is harsh, and it cannot be fixed with ordinary bolts to meet the requirements. [0003] In order to firmly fix mechanical equipment under severe corrosion and frequent shaking conditions, chemical casting materi...

Problems solved by technology

The disadvantages of this method are: 1. The effect of bolts to fix small mechanical equipment is good, but a lot of bolts are needed to fix larger weight mechanical equipment, which is difficult to operate; It is corroded, the strength is reduced, and there is a danger of sliding when the ship shakes, especially the main thruster of the ship has strict positioning requirements, heavy weight, and harsh environment, and ordinary bolts cannot meet the requirements.

However, the disadvantage of this material is that it needs high temperature to cure, it needs to be heated to more than 120 degrees, and there must be a special baking room, which restricts the use on ships.
