Problems solved by technology

[0004] The polylactic acid fiber currently used in the market is polymerized from L-lactic acid as a monomer, while PLLA has poor heat resistance, its glass transition temperature is only 57°C, and its melting point is 175°C. Therefore, how to avoid the poor heat resistance of polylactic acid fiber and bring adverse effects on the processing performance of subsequent products, prepare polylactic acid fiber wall decoration materials, overcome the defect of denaturation when it encounters high temperature, and reduce the impact on polylactic acid fiber. The strength of lactic acid fibers causes damage, and the short-process and functional use of polylactic acid materials is very meaningful for the environment we live in and the sustainable development of society.

Abstract

The invention discloses polylactic acid biodegradable wall decoration material which is composed of a colored polylactic acid fiber fluff layer, a low-temperature flocking adhesive layer and polylactic acid fiber organic textile fabric. The invention further discloses a manufacturing method of the polylactic acid biodegradable wall decoration material. The polylactic acid biodegradable wall decoration material not only is good in wet permeability, plump and thick in hand feeling, good in abrasive resistance and flame retardancy and not prone to falling fluff, but also has good antibacterial activity, anti-mite performance and a unique mildewproof function, meanwhile can be biodegraded completely, is safe and ideal material for interior decoration of houses, hotels, movie theatres and the like and has excellent market prospects.

Description

technical field [0001] The invention relates to a wall surface decoration material, in particular to a polylactic acid biodegradable wall surface decoration material with the functions of flame retardant, antibacterial, anti-mite and anti-mold. Background technique [0002] There are mainly two types of indoor wall decoration now, one is the woven fabric decorative cloth made of polyester filament fiber, and the other is painting paint and latex paint on the wall. For the former, because the polyester fiber will shrink after being heated, it is very easy to burn people if there is a fire. The method of paint, because the paint contains a large amount of organic solvents, will be released slowly in the subsequent use process, which is very harmful to the human living environment. Therefore, it is very necessary to choose healthy and environmentally friendly interior wall decoration materials. [0003] Polylactic acid fiber is a biomass fiber produced by non-grain crops (cass...
