Embodiment 1

[0034] 1) Disperse softwood fibers with a beating degree of 46°SR and water-soluble PVA fibers at 90°C in water, and use a fiber disintegrator to continuously stir for 3 minutes to evenly disperse the fibers in the water. Then add the waste FRP infiltrated by sodium lauryl sulfate, and continue to stir at a low speed for 30s to obtain the slurry to be treated. Wherein the coniferous wood fiber accounts for 80% of the total mass, waste FRP accounts for 9% of the total mass, PVA fiber accounts for 10% of the total mass, and sodium lauryl sulfate accounts for 1% of the total mass.

[0035] 2) Using a paper scraper, the slurry obtained in step 1) is copied into a wet paper sheet.

[0036] 3) Pressing the wet paper, the pressing pressure is 5MPa, the pressing time is 60s, and finally the dryness of the paper is controlled at 30-40%.

[0037] 4) The wet paper sheet is dried, the temperature of the dryer is 105° C., and the drying time is 5 minutes. After the wet paper sheet is com...

Embodiment 6

[0044] 1) Disperse the hardwood fiber with a beating degree of 43°SR and the water-soluble PVA fiber at 90°C in water, and use a fiber disintegrator to continuously stir for 2 minutes to make the fibers evenly dispersed in the water. Then add waste FRP soaked with polyethylene glycol p-isooctylphenyl ether, and continue to stir at a low speed for 20s to obtain a slurry to be treated. Wherein the hardwood fiber accounts for 65% of the total mass, the waste FRP accounts for 16% of the total mass, the PVA fiber accounts for 18% of the total mass, and the polyethylene glycol p-isooctyl phenyl ether accounts for 1% of the total mass.

[0045] 2) Using a paper scraper, the slurry obtained in step 1) is copied into a wet paper sheet.

[0046] 3) Pressing the wet paper, the pressing pressure is 4MPa, the pressing time is 40s, and finally the dryness of the paper is controlled at 30-40%.

[0047]4) The wet paper sheet is dried, the temperature of the dryer is 103° C., and the drying t...

Embodiment 7

[0049] 1) Disperse cotton fibers with a beating degree of 44°SR and 90°C water-soluble PVA fibers in water, and use a fiber disintegrator to continuously stir for 2 minutes to make the fibers evenly dispersed in water. Then add waste FRP soaked with dodecyltrimethylammonium bromide, and continue to stir at a low speed for 25s to obtain a slurry to be treated. Wherein cotton fiber accounts for 75% of the total mass, waste FRP accounts for 19% of the total mass, PVA fiber accounts for 5% of the total mass, and dodecyltrimethylammonium bromide accounts for 1% of the total mass.

[0050] 2) Using a paper scraper, the slurry obtained in step 1) is copied into a wet paper sheet.

[0051] 3) Pressing the wet paper, the pressing pressure is 4.5MPa, the pressing time is 50s, and finally the dryness of the paper is controlled at 30-40%.

[0052] 4) The wet paper sheet is dried, the temperature of the dryer is 104° C., and the drying time is 4.5 minutes. After the wet paper sheet is co...

Abstract

The invention relates to a plant fiber / waste FPR composite material and a preparation method thereof. The preparation method comprises the following steps: dispersing 50-80% of plant fibers and 5-20% of PVA fibers in water in percentages by weight and uniformly stirring, then adding 10-30% of waste FPR powder wetted by a wetting agent in percentages by weight, and uniformly stirring to obtain a fluid to be treated; and carrying out papermaking and molding on the fluid to be treated to obtain wet paper sheets, and squeezing and drying to obtain the plant fiber / waste FPR composite material. According to the preparation method disclosed by the invention, the waste FPR and the plant fibers serve as main materials, PVA fibers serve as adhesives, so that the plant fibers and the waste FPR are combined well, and the strength property of the material is improved effectively; the wetting agent facilitates dispersion of the waste FPR in a system, properties of the various components are played fully, the composite material with good properties is prepared by a wet-method papermaking technology, and reasonable reusing of resources is realized; and the preparation method is simple and feasible, and the recycling rate is high and can reach 100%.

Description

【Technical field】 [0001] The invention relates to the field of recycling waste materials, in particular to a plant fiber / waste FRP composite material and a preparation method thereof. 【Background technique】 [0002] FRP is also known as glass fiber reinforced composite material, commonly known as FRP (Fiber Reinforced Plastics), because of its superior properties such as: light weight and high strength, good corrosion resistance, good insulation performance, good thermal performance, strong designability, excellent workmanship, etc. , Since its development and research in 1958, it has been favored by all walks of life. According to relevant statistics, there are currently about 40,000 types of FRP products developed by countries around the world, which are mainly used in construction industry, chemical industry, automobile and railway transportation industry, electrical industry and communication engineering and other industries. [0003] Over the years, the application fie...
