Problems solved by technology

Since the bottom plate of the brake block is made of metal material, the weight of the whole product is large and the thermal conductivity is high. The heat generated by the brake friction will have an adverse effect on the mechanical equipment after being transmitted through the brake block; and the production process is complicated, the cost is high, and the production process is difficult. Large, difficult to control quality, inconvenient to use

Embodiment Construction

[0015] Such as Figures 1 to 5 As shown, a disc or drum brake pad 1, especially for disc or drum brake pads 1 for oil drilling rigs, mine hoists, heavy construction machinery, and heavy trucks, includes a base plate 11 and a base plate 11 The friction plate 12 that is bonded together by heat and pressure. The bottom plate 11 is made of fiberglass material, and the friction plate 12 is made of friction material.

[0016] Preferably, the glass fiber reinforced plastic material with nitrile-modified phenolic formaldehyde as the binder is used as the thermosetting material for manufacturing the bottom plate 11, and a polymer resin with a network structure is formed through condensation polymerization reaction, and mixed with glass fiber materials, fillers, lubricants, etc. Make the brake shoe bottom plate 11. Among them, 35-40% of resin, 45-50% of glass fiber (100-250mm in length) material, 10-15% of calcium carbonate, magnesium oxide, coloring agent, etc., and 1-1.2% of lubrica...

Abstract

A brake pad of brake is applied for drilling machine, the mine hoisting shaft and the heavy engine. It includes the soleplate and the grating piece in the soleplate. The plate is made from the glassfiber, which is combined with the grating piece. The plate is made up of the macromolecule heating colophony, the glass fibre, the stuffing and the lube. The two kinds of the materials combine and infiltrate together. It is light and the heat conductivity is low. This producing method is also disclosed.

Description

technical field [0001] The invention relates to a brake pad, in particular to a disc or drum brake pad suitable for oil drilling rigs, mine hoists, heavy engineering machinery or heavy-duty vehicles. The invention also discloses a method for manufacturing the brake block. Background technique [0002] Various brake shoes for brakes are known. These brake pads usually consist of a base plate of metal material and friction linings fixed thereon. When manufacturing brake pads, the friction disc is first made into a sheet, and then placed on a metal material base plate with the required geometric dimensions coated with an adhesive, and then pressurized and baked into a whole by the "splint method". Made into brake blocks; or, the steel plate is machined into a metal material base plate of the required geometric size, and then drilled, sand blasted, chemically cleaned, coated with adhesive, heat treated, put into a hot mold, and friction materials are added. Brake pads with fr...
