Abstract

The invention provides a method for preparing black sound-absorption flame retardant paper by using a gum dipping method. The method comprises the following steps of: making raw paper from a mixture containing glass fiber and masson pine fiber by adopting a wet process papermaking technology, and then preparing a gum dipping solution by using a binding agent, a fire retardant and color paste according to a certain sequence and proportion; and finally uniformly putting the prepared raw paper into the gum dipping solution to be dipped, absorbing gum on the surface of the paper subjected to gum dipping and then drying the paper. According to the method provided by the invention, the glass fiber and the masson pine fiber are selected, an appropriate production process is researched on the basis of a technical theory for production of special paper, and the black sound-absorption flame retardant paper which is high in strength, strong in flame retardance and even in surface luster is obtained. The method disclosed by the invention fully takes advantages of excellent properties of the glass fiber and the masson pine fiber, is used for making the black sound-absorption flame retardant paper which is high in strength and can be used as a filling material in a building wall by using a wet process papermaking technology and a dipping and drying process in preparation of special paper, can make full use of self properties of raw materials and is in simple in preparation process and excellent in finished-product property.

Description

technical field [0001] The invention belongs to the field of special fiber wet papermaking, and in particular relates to a method for preparing black sound-absorbing and flame-retardant paper by dipping. Background technique [0002] At present, sound-absorbing and flame-retardant paper is required in many civil and industrial buildings. This special material is one of the urgently needed special materials in the market because of its light weight, good sound-absorbing effect, and fire and flame-retardant properties. [0003] At present, domestic sound-absorbing and flame-retardant paper has disadvantages such as poor strength, brittleness, uneven surface color, poor decorative performance, and easy to be affected by moisture. When used for a long time, the performance stability is poor, and it cannot meet the requirements of building material selection. Contents of the invention [0004] The purpose of the present invention is to overcome the problems existing in the abo...
