Wide-width thin rubber sheet foaming technology based on infrared ray, steam and microwave composite heating

Abstract

The invention discloses a wide-width thin rubber sheet foaming technology based on infrared ray, steam and microwave composite heating. The technology comprises the following steps that step A, rubber, a foaming agent and a vulcanizing agent are mixed, and pressing is performed through a calender to form a wide-width thin rubber sheet; step B, air in a foaming furnace is heated through a steam radiator, so that the temperatures in the furnace are evenly distributed; step C, the wide-width thin rubber sheet is conveyed into the foaming furnace for heating, an infrared heating pipe of a feedingsegment is heated, so that the surface layer is quickly cured and formed, and under the combined effect of energy feedback microwaves radiated by a leaky antenna on a microwave heater wave guide pipeand air hot in the foaming furnace, the thin rubber sheet is evenly heated, vulcanized and foamed from inside to outside; step D, after foaming is completed, discharging is conducted. The invention aims at providing the wide-width thin rubber sheet foaming technology based on infrared ray, steam and microwave composite heating. According to the foaming technology, the wide-width thin rubber sheetis heated and foamed from inside to outside, the labor efficiency is improved, energy is saved, and the product qualification rate is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of rubber foaming, in particular to a wide-width thin rubber sheet foaming process based on infrared, steam and microwave composite heating. Background technique [0002] Foamed materials are relatively ubiquitous dense materials, and their most general common characteristics are low density, light weight, large specific area, high specific mechanical properties, and good damping properties. Due to its excellent physical and mechanical properties and high cost performance, foamed materials have become an excellent engineering material with dual properties of function and structure. It is a class of functional structural materials that are widely used and have great application potential. The application of this kind of material involves industries such as aviation, aerospace, atomic energy, medicine, environmental protection, metallurgy, mechanical construction, electrochemistry and petrochemical industry, a...

AI Technical Summary

Problems solved by technology

According to relevant investigations and studies, the original foaming technology basically adopts the method of heating air to form hot air circulation to heat and foam the thin rubber sheet from the outside to the inside. The basic heating sources usually use electric heating, infrared rays, heat transfer oil, and natural gas. These methods have high energy consumption, are not environmentally friendly, and have a low qualified rate of finished products.
