Problems solved by technology

However, since waste porcelain powder basically has no plasticity, water is used as a mixing aid. Due to the poor plasticity and bonding performance of the mixed material, the plasticity of the ceramic material added with waste porcelain powder will become poor and it is not easy to form

Abstract

The invention provides a method for a low-cost manufacturing method for a ceramic base of an LED illuminating lamp. The method is characterized by: 1) adopting waste ceramics in a ceramic industry; 2) mixing and grinding the waste ceramics and kaolin; 3) respectively adding water glass, a tetramethylammonium hydroxide solution and a ammonium sulfate solution to the mixture through spraying; 4) heating paraffin wax, followed by adding accessory ingredients, mixing the resulting mixture through stirring, then adding the resulting mixture to the mixture from the step 3), followed by carrying outimpact briquetting to form a green body in a die; 5) annealing the green body to obtain the finished product. According to the present invention, demolding can be performed in 10-100 seconds; a forming process does not contain a green body dehydration process, such that forming time is substantially saved, efficiency is improved. In addition, the green body has high intensity so as to form an exquisite shape and an exquisite structure through matching with a steel mould, and satisfy a precision requirement of a structure size of the base of the LED illuminating lamp.

Description

technical field [0001] The invention relates to a method for manufacturing ceramic products, in particular to a method for manufacturing a ceramic lamp holder of an LED lighting lamp. Background technique [0002] The lamp holder of the LED light bulb can be made of a metal material as a whole due to heat dissipation requirements, or a metal material is used as a heat-conducting medium, and a ceramic body is used as a lamp holder, which is combined with a metal heat-conducting medium to form a lamp holder. Ceramic lamp holders have high requirements for shape, structure and dimensional accuracy. According to the existing technology of ceramic lamp holder, porcelain clay is injected into a plaster mold to form a ceramic body, and then calcined at high temperature. However, due to the poor precision of the plaster mold, complex cavity and structure cannot be formed, and the ceramic body is taken out by opening the mold The protruding stripes formed by the gap between the modu...
