Abstract

The invention discloses a flame retardant sound absorbing board based on polyester fiber material and a production process thereof. Waste plastics are used as raw materials; the regenerated polyester staple fiber and regenerated low melting skin core type polyester staple fiber are prepared by melt spinning; the flame retardant is sprayed on the upper surface of the board uniformly, and the partial thickness of the lower surface of the board is dipped into the flame retardant; the flame retardant sound absorbing board is obtained by predrying, cooling down with cold air after calendering and cutting. The production process comprises the following steps: (1), preparing the raw materials; (2), mixing a formation mesh of the regenerated staple fiber; (3), reinforcing the fiber mesh; (4), spraying the flame retardant, and being dipped into the lame retardant; (5), predrying, calendering, and cooling; (6), cutting and arranging. According to the method of spraying and immersion which work at the same time and by spraying the flame retardant on the upper surface and dipping the lower surface into the flame retardant, the good flame retardant effect of the sound absorbing board is effectively guaranteed; a good formability of the sound absorbing board after drying is ensured, and the hardness is up to standard.

Description

technical field

[0001] The invention relates to the technical field of flame-retardant boards, in particular to a flame-retardant sound-absorbing board based on polyester fiber materials and a production process thereof. Background technique

[0002] Fire is the most common disaster that seriously endangers people's lives and property and directly affects economic development and social stability. In recent years, with the widespread use of new energy, new materials, and new equipment, as well as the continuous expansion of urban construction scale and the improvement of people's material and cultural living standards, the casualties and property losses caused by fires are also increasing. Therefore, the fire performance of sound-absorbing materials is crucial, and the concept of fire prevention has become the most important safety requirement in various fields. The advent of flame-retardant fiberboards has solved the problem of flammability of traditional interior decorati...
