Abstract

The invention discloses a making method of ultrathin low-weight sound-absorbing decoration paper. The existing sound-absorbing material is large in thickness and high in weight, and easily generates a fiber or dust and the like to damage a surrounding environment. The method comprises the steps that a plant fiber is beat till 15-30<0>SR is achieved, and mixed with a non-plant fiber; a chemical additive is added to a mixed fiber; the mixed fiber is subjected to paper making by a round wire or inclined wire paper machine to form raw paper; a fire retardant, an adhesive and the chemical additive are mixed to form a coating fluid; the raw paper is subjected to in-machine coating or out-machine coating to form semifinished sound-absorbing decoration paper; the semifinished sound-absorbing decoration paper is dried, subjected to surface finishing, and reeled into the sound-absorbing decoration paper; and a sound-absorbing paper decoration material which is good in strength, high in air permeability, small in thickness, light in weight, good in flame retardance, excellent in sound absorptivity, and good in decoration effect is obtained.

Description

technical field [0001] The invention relates to a novel ultra-thin and low-weight sound-absorbing paper manufacturing method, in particular to a sound-absorbing paper material suitable for decorative materials and a manufacturing method thereof. Background technique [0002] With the development of modern society, people's requirements for the sound environment are getting higher and higher. Sound absorption and noise reduction and space privacy requirements have evolved into an important issue that needs to be solved urgently for the coordinated development of high technology, the environment and human beings. The new sound absorption and noise reduction The structure, acoustic properties and application of materials are an important subject involving interdisciplinary subjects. With the rapid growth of society's demand for sound-absorbing materials, the performance of sound-absorbing materials has more and higher requirements. The sound-absorbing material has changed from...
