Scale-like potassium titanate preparation method and brake pad

Abstract

The invention discloses a scale-like potassium titanate preparation method which comprises the steps of mixing raw materials-smashing-once calcining-washing in solution-acid and alkali treating-filter pressing-drying-secondary calcining. In acid and alkali treating, a product is soaked in sulfuric acid solution to be treated, 99% or more of ions of the product are replaced by hydrogen ions or hydronium ions, and the product is converted into multilayer titanic acid; furthermore, 5 to 40 equivalent weight of alkali compound with an interlayer expansion effect acts on the multilayer titanic acid to adjust the thickness of the multilayer titanic acid. The invention further discloses a brake pad. A potassium hexatitanate friction enhancing material prepared through the preparation method disclosed by the invention has the following advantages: 1, the material is poisonless and harmless; 2, the material has stable performance, friction coefficients hardly change along with temperature change, and the defect that a non-asbestos organic formula has poor high temperature recession and high temperature abrasion is overcome; 3, use temperature is high and can be 1000 DEG C; 4, the material is wear-resistant and has long service life; 5, the material can be applied to the brake pad and is free of sound in brake, free of corroding hubs and free of environmental pollution.

AI Technical Summary

Benefits of technology

This invention relates to an improved type of material that can be used for making materials more resistant against heat or abrasion damage without adding too much weight compared to traditional methods like phenol formaldehyde resin bonding agents. It also has better durability than other types of binders due to its lower melting point (Tm) at temperatures above 1900C.

Problems solved by technology

Technological Problem: While certain types of metal oxides can be useful as raw materials or filler compounds due to their unique structure and physical property values they exhibit various technical effects including improved lubrication efficiency, increased durability against abrasives, better impact strength compared with other compositions containing calcium but without harmful elements like lead. These new products could replace existing ones while maintaining their beneficial attributes over time.
