Embodiment 1

[0030] A plywood modified by nanometer ionic liquid comprises the following steps:

[0031] (1) Preparation of nano-ionic liquid: uniformly mix nano-diatomite and nano-graphene to obtain composite nanoparticles, add a mixture of deionized water and glycerin to the reaction kettle, and then press 40g of the above-mentioned composite nanoparticles: The ratio of 400mL was evenly dispersed in the mixed solution of deionized water and glycerin, heated to 80°C in a water bath, kept for 35min, then adjusted to 40°C, and stirred at 1500r / min for 2 hours to obtain a nanoparticle dispersion, which was injected into the nanoparticle Add isoprene monomer, methacrylonitrile monomer, and initiator to the particle dispersion in sequence, and react for 15 hours after mixing evenly. Washing with deionized water, vacuum drying to constant weight, and then evenly dispersing the composite reaction nanoparticle product in the ethanol solution, and ultrasonically dispersing to obtain the nanopartic...

Embodiment 2

[0046] A plywood modified by nanometer ionic liquid comprises the following steps:

[0047] (1) Preparation of nano-ionic liquid: uniformly mix nano-diatomite and nano-graphene to obtain composite nanoparticles, add a mixture of deionized water and glycerin to the reaction kettle, and then press 45g of the above-mentioned composite nanoparticles: The ratio of 400mL was evenly dispersed in the mixed solution of deionized water and glycerol, heated to 85°C in a water bath, kept for 38min, then adjusted to 40°C, and stirred at 1500r / min for 2 hours to obtain a nanoparticle dispersion, which was injected into the nanoparticle Add isoprene monomer, methacrylonitrile monomer, and initiator to the particle dispersion in sequence, and react for 16 hours after mixing evenly. Washing with deionized water, vacuum drying to constant weight, and then evenly dispersing the composite reaction nanoparticle product in the ethanol solution, and ultrasonically dispersing to obtain the nanopartic...

Embodiment 3

[0062] A plywood modified by nanometer ionic liquid comprises the following steps:

[0063] (1) Preparation of nano-ionic liquid: uniformly mix nano-diatomite and nano-graphene to obtain composite nanoparticles, add a mixture of deionized water and glycerin to the reaction kettle, and then press 42g of the above-mentioned composite nanoparticles: The ratio of 400mL was uniformly dispersed in the mixed solution of deionized water and glycerin, heated in a water bath to 82°C, kept for 36min, then adjusted to 40°C, and stirred at 1500r / min for 2 hours to obtain a nanoparticle dispersion, which was injected into the nanoparticle Add isoprene monomer, methacrylonitrile monomer, and initiator to the particle dispersion in sequence, and react for 15.5 hours after mixing evenly. Washing with deionized water, vacuum drying to constant weight, and then evenly dispersing the composite reaction nanoparticle product in the ethanol solution, and ultrasonically dispersing to obtain the nanop...

Abstract

The invention discloses a plywood modified by nanometer ionic liquid, which relates to the field of environmental protection technology, and comprises the following steps: (1) preparation of nanometer ionic liquid; (2) thermal steaming treatment of eucalyptus board; (3) modification of nanometer ionic liquid Eucalyptus board; (4) gluing on the surface of the eucalyptus board; (5) hot-press forming of three-ply plywood, the plywood prepared by the invention has good bonding strength and flame retardancy.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a plywood modified by nanometer ionic liquid. Background technique [0002] Wood is a traditional furniture material, which has something to do with its beautiful and delicate texture, warm feel and easy processing. There are two main types of wood suitable for making furniture, softwood and hardwood. Softwood is easy to process, light in weight and light in color, and cheap in price; hardwood is not easy to process, heavy in quality but durable, and its color, texture, and pattern are eye-catching. [0003] In addition to natural wood panels, various wood-based panels are also widely used in the production of furniture. [0004] (1) Plywood. Plywood is made by cutting wood into planks, applying glue, and applying a lot of pressure. Since the layers of veneers coated with glue are arranged crosswise, the strength and stability are guaranteed. [...
