Problems solved by technology

Since the jute fiber layer and the polyester fiber layer are stacked at intervals, and the jute fiber and the polyester fiber are not entangled with each other, the board prepared by this interval stacking has small and few pores on the board, and the board is relatively hard. , resulting in poor air permeability and poor sound absorption

Abstract

The invention relates to the technical field of sound absorption panels, in particular to a polyester fiber plate based on China hemp straw waste and a production technology of the polyester fiber plate. The China hemp straw waste is used as a raw material to prepare China hemp fiber, low-melting-point fiber is prepared through smelting spinning, a fiber plate body is prepared through mixing, opening, carding, lapping and needling reinforcement, a fire retardant is sprayed on the fiber plate body for drying, press polishing and cooling, and the polyester fiber plate is obtained after cutting;and the polyester fiber plate is prepared from the following components in parts by weight: 50-60 parts of the China hemp fiber and 40-50 parts of the low-melting-point fiber, and a NRC sound absorption coefficient of the polyester fiber plate is greater than or equal to 0.90. The production technology of the polyester fiber plate comprises the following steps that (1), the raw material is prepared; (2), mixing is carried out to form a mesh; (3), the fiber mesh is reinforced; (4), the fire retardant is sprayed; (5), drying, press polishing and cooling are carried out; and (6), cutting and tidying are carried out. The polyester fiber plate is environment-friendly and saves energy, has extremely high moisture absorption performance and air permeability, has a good sound absorption effect, can effectively resist bacteria, restrain mites, prevent mildew, insulate sound, can be degradable, and has high strength.

Description

technical field [0001] The invention relates to the technical field of sound-absorbing boards, in particular to a polyester fiber board based on hemp straw waste and a production process thereof. Background technique [0002] The full name of polyester fiber sound-absorbing board is polyester fiber decorative sound-absorbing board, which is a decorative material with sound-absorbing function made of polyester fiber as raw material by hot pressing. Polyester fiber sound-absorbing board has the characteristics of sound-absorbing, heat-insulating and heat-insulating, and the material of the board is uniform and firm, full of elasticity, toughness, wear resistance, impact resistance, tear resistance, not easy to be scratched, and large board width. Because of its characteristics of decoration, heat preservation, flame retardancy, environmental protection, light weight, easy processing, stability, impact resistance, and easy maintenance, it has become the first choice of decorati...
