Method for making black sound absorption and flame retardation paper through adhesive spraying

Abstract

The invention provides a method for making black sound absorption and flame retardation paper through adhesive spraying. The method comprises the following steps: mixing glass fibers and vegetable fibers through a wet papermaking technology, respectively processing an adhesive and a flame retardant and color past mixture to prepare solutions having certain concentrations, uniformly spraying the surface of raw paper with a prepared adhesive solution, and drying at a controlled drying temperature for a controlled time to guarantee the flattening and no wrinkling of dried paper. The glass fibers and the vegetable fibers selected in the invention are processed through a production technology theory of special paper to obtain black sound absorption and flame retardation paper having the advantages of high strength, strong flame retardation and uniform surface color. In the invention, the excellent performances of the glass fibers and the vegetable fibers are fully performed, and the high-quality black sound absorption and flame retardation paper which can be used in the walls of buildings as a filler is obtained through the wet papermaking technology and an adhesive spraying and drying technology in the preparation of the special paper. The method provided by the invention has the advantages of full utilization of the self characteristics of raw materials, simple preparation process, and excellent performances of finished products.

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 spraying and gluing. 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
