Problems solved by technology

As people pay more attention to the living environment, everyone has heard of the term formaldehyde, especially in newly renovated houses. Many furniture, decoration materials, and paints have excessive formaldehyde, which is extremely harmful to human health; As a high-strength flat plate made of wood fiber and thermosetting resin through high-pressure polymerization, special boards are prone to excessive formaldehyde emission when used in outdoor places such as schools, hospitals, airports, stations, hotels, shopping malls, and office buildings. , affecting the environment

Embodiment 1

[0021] Such as figure 1 As shown, the new E0 grade plate in this embodiment includes a substrate 1, and the outside of the substrate 1 is coated with a decorative paper 2 treated with a mixed solution of melamine-formaldehyde-organic particles; the decorative paper 2 is cured by electron beams before being coated on the substrate 1 One layer of electron beam curing coating 3, the electron beam curing coating 3 is composed of the following raw materials by weight percentage: polyfluoroacrylic acid 40%, epoxy acrylic acid 8%, co-crosslinking agent 10%, hexanediol diacrylate 15% %, light stabilizer 1%, ultraviolet absorber 1%, flame retardant 4%, coupling agent 0.5%, leveling agent 0.5%, gold powder 5%, silver powder 3%, dispersant 1%, nano titanium dioxide 8%, Nano-silver oxide 3%, above-mentioned material obtains electron beam curing coating resin through stirring and mixing, wherein co-crosslinking agent is trimethylolpropane triacrylate; Formaldehyde by weight, organic parti...

Embodiment 2

[0023] The manufacturing method of the novel E0 grade sheet material of embodiment 1, comprises the steps:

[0024] A. Electron beam curing coating resin preparation: Add the following raw materials into the mixer by weight percentage, including 40% polyfluoroacrylic acid, 8% epoxy acrylic acid, 10% co-crosslinking agent, 15% hexanediol diacrylate, Light stabilizer 1%, UV absorber 1%, flame retardant 4%, coupling agent 0.5%, leveling agent 0.5%, gold powder 5%, silver powder 3%, dispersant 1%, nano titanium dioxide 8%, nano oxide Silver 3%, start the stirrer and heat to 50°C, stir evenly, and vacuumize to obtain electron beam curing coating resin solution.

[0025] B. Immerse the decorative paper in the mixed solution of melamine-formaldehyde-organic particles, dry and rewind to ensure that the obtained decorative paper has a uniform weight, a smooth surface, and the light fastness rating of the printing ink is not less than 6.

[0026] C. Glue coating and curing. Apply the e...

Embodiment 3

[0034] A manufacturing method of a novel E0 grade plate, on the basis of Embodiment 2, the manufacturing method of this embodiment has the following differences:

[0035]In step B, the grammage of the decorative paper before impregnation is 115 g / m2, the amount of glue applied during impregnation is 105 g / m2, the volatile matter is 3.5%, and the light fastness rating of the printing ink is grade 6 to ensure uniform impregnation of the decorative paper.

[0036] In step C, the coating thickness is 0.15 mm.

[0037] In step E, first raise the temperature to 50°C to preheat the decorative paper, so that the melamine-formaldehyde glue on the substrate melts, keep the pressure on the platen and raise the temperature again to make the temperature rise slowly to 155°C, maintain the pressure to 10.0MPa, and keep it warm for 35 minutes After cooling down to normal temperature and removing the pressing plate, compared with the traditional hot pressing method of pressurizing once to the ...

Abstract

The invention relates to a novel E0 grade plate and a preparation method thereof. The novel E0 grade plate comprises a base plate, and the outside of the base plate is wrapped by decorative paper, which is processed by melamine-formaldehyde-organic particle mixed solution; the surface of the decorative paper is wrapped by an electron beam cured coating. According to the novel E0 grade plate, the decorative paper on the surface is impregnated by the melamine-formaldehyde-organic particle mixed solution, of which the organic particles are mesoporous double-layer organic silicon spheres in a double-layer porous structure, so that formaldehyde in the novel E0 grade plate can be absorbed by the organic particles and further avoid being released.

Description

technical field [0001] The invention relates to the technical field of building decoration materials, in particular to a novel E0 grade plate and a preparation method thereof. Background technique [0002] Anti-fold special board has excellent stability and is easy to clean and maintain, so it has a wide range of applications. Anti-fold special board is widely used in large public places such as schools, hospitals, airports, stations, hotels, shopping malls, and office buildings. Kitchen countertops, vanity tops, dining tables, desks, door leaves, bathroom and toilet cubicles in public spaces, sinks, reception counters, lockers, ceilings, desks and office cubicles, etc. As people pay more attention to the living environment, everyone has heard of the term formaldehyde, especially in newly renovated houses. Many furniture, decoration materials, and paints have excessive formaldehyde, which is extremely harmful to human health; As a high-strength flat plate made of wood fiber...
