Processing equipment and method for flame retarding modification of blend fiber felt

Abstract

The invention belongs to the technical field of modification processing machinery and relates to processing equipment for flame retarding modification of blend fiber felt. The processing equipment for flame retarding modification of the blend fiber felt comprises a conveying transmission mechanism (a), an impregnation mechanism (b), a pressing mechanism (c), a drying mechanism (d) and a winding mechanism (e) which are sequentially connected from front to back, wherein the impregnation mechanism (b) comprises an impregnation tank (2) and three parallel impregnation rollers (21, 22 and 23) which are located in the impregnation tank (2); concave grooves (40) for containing liquids are formed in surfaces of the impregnation rollers (21, 22 and 23). The blend fiber felt produced by the processing equipment for flame retarding modification of the blend fiber felt is high in flame retardation, redundant flame-retardant liquids are easy to recover, a flame retardant is low in consumption and is evenly dispersed, the processing process is environment-friendly and free of pollution, the whole production line can operate continuously, and the production efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of material processing and machinery, and relates to a flame-retardant modification processing equipment and processing method of a blended fiber felt. Background technique [0002] At present, there is no effective set of processing equipment for flame-retardant modification of formed blended fiber felt products in the market. In order to make the blended fiber mat meet the flame-retardant requirements, most people can only find a way on the raw materials, and process it into a blended fiber mat by selecting a flame-retardant and modified raw material for non-woven processing. The molding process of felt is also limited, and the flame retardancy of the finished product is also difficult to control, and the range of raw material selection is narrowed, and the quality of the product is unstable, which can no longer meet the growing actual demand.
