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 process of a flame-retardant and environment-friendly mixed felt, which relates to the technical field of mixed felt processing, including feeding and opening, picking cotton, primary needling, dipping and drying, baking, water washing and drying, and secondary needling At the same time, the invention also discloses an impregnation and drying integrated machine for impregnating flame retardants and drying treatment. The mixed felt of the invention uses a variety of materials for mixing. By impregnating flame retardants, it not only has excellent Sound insulation, flame retardant performance, and also has good thermoplastic molding performance. During the production process, through controlling the acupuncture parameters, drying temperature and time, etc., although the thickness is relatively thin, the product finally meets the 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 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 insula...
