Problems solved by technology

For the former, the guide roller needs to give the mixed felt a greater tension, so that when the mixed felt passes through the guide roller, the flame retardant inside it is easy to be squeezed out, which affects the impregnation effect, and also causes the cleaning and maintenance of the guide roller. The disadvantages of inconvenience and slow feeding speed, after impregnating the flame retardant, it needs to be soaked with liquid, which will easily cause serious wrinkles and tightness of the mixed felt after drying.
For the latter, it is easy to have insufficient infiltration

Abstract

The invention discloses a production technology of a flame-retardant environment-friendly mixed felt, and relates to the technical field of mixed felt processing. The production technology comprises loading opening, cotton grabbing, primary needling, dipping and drying, baking, washing and drying, secondary needling, and other steps, and meanwhile, the invention also discloses a dipping and dryingintegrated machine used for dipping in a fire retardant and drying treatment. The mixed felt provided by the invention is formed by mixing of various materials, by dipping in the fire retardant, themixed felt not only has excellent sound insulation performance and flame resistance, but also has excellent thermoplastic forming performance, and in a production process, by well controlling of a needling parameter, drying temperature and time, and so on, thickness is relatively lower, but a product finally can satisfy expected requirements.

Description

technical field [0001] The invention belongs to the technical field of mixed felt processing, and in particular relates to a production process of a flame-retardant and environment-friendly mixed felt. Background technique [0002] The noise of the compressor is the main noise source of the outdoor unit of the air conditioner (especially the small and medium-sized models), and the noise level directly determines the noise value and sound quality of the air conditioner. At present, compressor sound insulation cotton is widely used in the industry to wrap the compressor, so as to attenuate the noise of the compressor. In order to improve the noise reduction, the sound insulation cotton used to wrap the compressor generally consists of a sound absorption layer and a sound insulation layer to form a composite sound insulation cotton to reduce the noise of the compressor. [0003] At present, there are many kinds of sound insulation cotton materials on the market, and the sound ...
