Waterproof and environment-friendly paper honeycomb composite board for automotive interior, and preparation method of composition board

The invention discloses a waterproof and environment-friendly paper honeycomb composite board for automotive interior, and a preparation method of the composition board. The waterproof and environment-friendly paper honeycomb composite board is formed by compounding a piece of non-woven fabric, a hot melt adhesive membrane, a bamboo fiber felt, another hot melt adhesive membrane, a paper honeycomb core, another hot melt adhesive membrane, a GMT felt and another hot melt adhesive membrane from bottom to top; each hot melt adhesive membrane is prepared from the following raw materials in parts by weight: 20-30 parts of ternary co-polypropylene, 10-20 parts of a vinyl-propylene copolymer, 5-10 parts of C5 / C9 copolymer resin, 2-4 parts of high molecular weight polypropylene (PP) wax and 1-2 parts of an antioxidant; the bamboo fiber felt is prepared from the following raw materials in parts by weight: 40-50 parts of bamboo fiber, 5-10 parts of brucite powder, 5-8 parts of sepiolite powder, 10-15 parts of a urea-formaldehyde resin adhesive, 7-12 parts of silicone acrylic emulsion, 1-2 parts of nano titanium dioxide and 4-6 parts of castor oil. The waterproof and environment-friendly paper honeycomb composite board has the characteristics of being less in odor and less in volatile organic compounds (VOC), resisting low temperature and heat aging, being permanent in moisture resistance, mould-proof and free from undesirable odor, and the like, and is non-toxic and environmentally-friendly.

Modification method of ramie fibers

The invention relates to a modification method of ramie fibers. The modification method comprises the following steps: step 1, proportioning cottonseed shell ash, rice straw ash and sodium hydroxide according to a weight ratio of 10 to (5-8) to (1-2) to obtain a mixture, adding the mixture into water which is 10-15 times the total weight of the mixture, boiling and preparing a modified solution; step 2, adding the ramie fibers into the modified solution to be completely immersed, and cooking for 2-4 hours; and step 3, taking the ramie fibers out of the modified solution, washing the ramie fibers with clear water, and naturally drying the ramie fibers in air. Compared with the prior art, the method disclosed by the invention has the advantages that characteristics such as degree of crystallinity and degree of orientation of the ramie fibers are improved, a prodding and itching feeling generated when the ramie fibers are in contact with a human body is eliminated to certain extent, unique fiber hole cavity structures of the ramie fibers are not damaged, and grooved cavities in the middle of the fibers are not damaged, so that characteristics such as bacteria resistance and bacteriostasis, deodorization and adsorption, moisture absorption and ventilation, mildew prevention and wear resistance of the ramie fibers can be kept.

Ramie fiber mattress production method

The invention relates to a ramie fiber mattress production method which includes the steps: firstly, quantitatively feeding and carding ramie fibers; secondly, performing mesh laying, needle punching and thermoforming; finally, cutting the ramie fibers. The ramie fibers adopt modified ramie fibers, a modified method of the ramie fibers includes the steps: firstly, matching cotton seed shell ash, rice straw ash and sodium hydroxide according to the weight ratio of 10:(5-8):(1-2), adding the cotton seed shell ash, the rice straw ash and the sodium hydroxide into water with the weight accounting for 10-15 times of the total weight of the cotton seed shell ash, the rice straw ash and the sodium hydroxide, and boiling mixture to prepare modified solution; secondly, adding the ramie fibers into the modified solution, enabling the ramie fibers to be completely immersed by the modified solution, and stewing mixture for 2-4h; thirdly, taking out the ramie fibers from the modified solution, washing the ramie fibers by the aid of clear water, and naturally air-drying the ramie fibers. According to the method, characteristics such as crystallizing degree and orientation degree of the ramie fibers are changed, prodding and itching sensation is removed when the ramie fibers contact with human bodies to some extent, and unique pore cavity structures and middle ditch-shaped cavities of the ramie fibers cannot be broken, so that a prepared ramie fiber mattress keeps characteristics such as natural bacterium resistance, bacterium inhibition, odor removal, adsorption, moisture absorption, permeability, mildew resistance and abrasion resistance of the ramie fibers.

Preparation method of tea shell carbon fibers

The invention provides a preparation method of tea shell carbon fibers. The preparation method is characterized by comprising the following steps of (1) preparing tea shell carbon powder; (2) preparing a tea shell carbon aqueous dispersion liquid; (3) performing pretreatment of fibers; and (4) coating the fibers with tea shell carbon. Tea shells are prepared into tea shell carbon aqueous dispersion liquid, and the tea shell carbon aqueous dispersion liquid is added into a dipping barrel, so that the surfaces of fibers are evenly coated with the tea shell carbon aqueous dispersion liquid to prepare the tea shell carbon fibers, the technical problem of preparation of the tea shell carbon fibers is solved, and the whole preparation method operates at low temperature, is safe and environmentally friendly and cannot pollute the environment. The tea shell carbon fiber prepared by the novel preparation method has natural functions of resisting and inhibiting bacteria, generating negative ions, emitting far infrared rays and removing peculiar smell, and textiles prepared from the tea shell carbon fibers have the characteristics of smoothness, fineness, good hygroscopicity and the like. Thetea shell carbon fiber can be applied to the field of textile products such as clothes, household textiles, underwear and masks, and has a wide market prospect.
