Embodiment 1

[0020] Take by weighing polylactic acid fiber 22kg, regenerated fiber 25kg, jute fiber 40kg respectively, the total amount of taking by weighing three kinds of fibers is 87Kg each time, mix in mixer and become mixed fiber. Respectively weigh 8 kg of flame retardant, 3 kg of nano-montmorillonite and 2 kg of initiator, mix uniformly, stir at a high speed for 10 minutes, and the screw speed is 100 rpm, and then extruded by the screw to cool and pulverize into powder.

[0021] After the mixed fiber is opened by the bale opener, it is sent to the mixed opener for further opening, and then sent to the cotton box, and the cotton box outputs the mixed fiber to the air-laid machine with a conveying curtain. Add the powder into the powder applicator, set the speed of the applicator spreading roller to 1.5 rpm, output the powder on the conveying curtain, and send it into the air-laid machine together with the mixed fibers to form a fiber web and convey it to in the oven. Control the ove...

Embodiment 2

[0026] Take by weighing 40kg of polylactic acid fiber, 25.9kg of regenerated fiber, and 22kg of jute fiber respectively, and the total amount of the three kinds of fibers is 87.9Kg each time, and they are mixed uniformly in a mixer to form a mixed fiber. Respectively weigh 10kg of flame retardant, 2kg of nano-montmorillonite and 0.1kg of initiator, mix uniformly, stir at a high speed for 15min at a screw speed of 150rpm, extrude, cool, and pulverize into powder.

[0027] After the mixed fiber is opened by the bale opener, it is sent to the mixed opener for further opening, and then sent to the cotton box, and the cotton box outputs the mixed fiber to the air-laid machine with a conveying curtain. Add the powder into the powder applicator, set the speed of the applicator spreading roller to 3 rpm, output the powder on the conveying curtain, and send it into the air-laid machine together with the mixed fibers to form a fiber web and convey it to in the oven. Control the tempera...

Embodiment 3

[0032] Take by weighing polylactic acid fiber 29kg, regenerated fiber 30kg, jute fiber 28kg respectively, the total amount of taking by weighing three kinds of fibers is 87Kg at every turn, mixes in mixer and becomes mixed fiber. Respectively weigh 9kg of flame retardant, 3kg of nano-montmorillonite and 1kg of initiator, mix uniformly, stir at a high speed for 15min at a screw speed of 150rpm, extrude, cool, and pulverize into powder.

[0033]After the mixed fiber is opened by the bale opener, it is sent to the mixed opener for further opening, and then sent to the cotton box, and the cotton box outputs the mixed fiber to the air-laid machine with a conveying curtain. Add the powder into the powder applicator, set the speed of the applicator spreading roller to 2 rpm, output the powder on the conveying curtain, and send it into the air-laid machine together with the mixed fibers to form a fiber web and convey it to in the oven. Control the temperature of the oven at 160°C, po...

Abstract

The invention discloses a polylactic acid composite fiber interior material and a preparation method thereof. The polylactic acid composite fiber interior material consists of the following components in percentage by weight: 22 to 40 percent of polylactic acid fiber, 25 to 30 percent of regenerated fiber, 22 to 40 percent of natural fiber, 8 to 10 percent of flame retardant, 2 to 3 percent of nano-montmorillonite and 0.1 to 2 percent of initiator. The preparation method comprises the following steps of: uniformly mixing the two-component polylactic acid fiber, the regenerated fiber and the natural fiber to obtain mixed fibers; uniformly mixing the flame retardant, the nano-montmorillonite and the initiator, stirring, cooling, and grinding into powder; opening the mixed fibers by using an opener, further opening by using a hopper blending opener, feeding into a feed box, and outputting by using a transport lattice; and putting the powder onto the transport lattice, making the powder and the mixed fibers fed into an air-laid web forming machine to obtain a web, and polymerizing the web in an oven. The prepared interior material has high environment friendliness, elasticity, sound absorption, flame retardancy and thermal insulation.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and specifically relates to an interior material compounded by polylactic acid bicomponent fiber, regenerated fiber and natural fiber, which is used for automobile heat insulation pads, home appliance sound insulation pads, ship interior decoration, etc. . Background technique [0002] At present, most of the raw materials for interior sound insulation and heat insulation interior materials such as automobiles and home appliances come from petroleum-derived polymer materials. With the rising energy prices and increasingly prominent environmental problems, it has become a development trend to replace traditional petroleum products with biodegradable biomaterials. [0003] Polylactic acid is formed by the polymerization of L-lactic acid fermented from starch and sugar. It is a completely biodegradable synthetic fiber. All agricultural products such as corn and even ordinary plants can ext...
