preparation example Construction

[0037] The preparation method of the bottom plate structure of the vibration damping press comprises the following steps:

[0038] 1) First prepare the damping composite material, weigh the base material and filler according to the formula, and send them into the strong mixer in turn, and fully stir and mix. The mixing time is 8-15min to obtain the mixed raw material, and the temperature of the mixed raw material is raised to 100-140°C , add additives, stir for 5-10 minutes, fully dissolve, and prepare damping slurry;

[0039] 2) Using CNC glue spraying technology, the conveying roller transports the upper metal plate and the lower metal plate to the automatic glue spraying system at a uniform speed at the same time, and the automatic glue spraying equipment evenly coats damping slurry on the inner surface of the metal plate;

[0040] 3) laying a layer of mesh-shaped glass fiber layer film 40 on the lower metal plate coated with damping slurry;

[0041] 4) The upper and lower...

Abstract

The invention discloses a damping composite material, a damping pressing machine bottom plate structure and a refrigerator. The damping composite material comprises a base material, filler and an aid, wherein the base material comprises 40 to 50 parts of epoxy resin; the filler comprises 20 to 25 parts of polyurethane polymers, 20 to 40 parts of glass fibers, 5 to 15 parts of barium sulfate, 10 to 20 parts of mica sheet, 3 to 8 parts of talcum powder, 5 to 10 parts of graphite, 5 to 20 parts of nano silicon dioxide, 5 to 10 parts of zinc oxide crystal whisker, and 5 to 10 parts of adhesives; and the content of the aid is 5 to 10 parts by weight. The damping pressing machine bottom plate structure comprises an upper metal plate, a middle damping layer and a lower metal plate, wherein the middle damping layer is made of the damping composite material. The damping pressing machine bottom plate structure is used as a compressor supporting plate to be applied to a refrigerator, so that the overall noise of the refrigerator is obviously reduced, and the overall silence effect is improved.

Description

technical field [0001] The invention belongs to the technical field of damping and vibration-reducing materials, and in particular relates to a damping composite material, a vibration-damping press bottom plate structure using the damping composite material, and a refrigerator using the vibration-damping press bottom plate structure. Background technique [0002] Traditional refrigerator compressors are fixed and supported by the bottom plate of the compressor, and then assembled and fixed to the machine compartment of the refrigerator to form an important component of the refrigeration system of the refrigerator. Plates and other metal plates, the connection between the compressor and the support base of the compressor is a rigid connection structure. During the working process of the refrigeration system of the refrigerator, the vibration of the compressor and the eruption vibration of the refrigerant flow in the refrigeration system are transmitted to the box through the s...
