Problems solved by technology

[0006] The existing aging-resistant flooring will coat a layer of aging-resistant paint film on the surface of the solid wood floor during the preparation process. After being exposed to light for a long time, the surface paint film will change color or even crack, which will cause the paint film to fail to protect the floor. , and the curing agent will be used when the paint film is cured, the use of the curing agent will cause the emission of organic volatiles, which will pollute the environment

Embodiment 1

[0040] An aging-resistant EB floor is made by the following steps:

[0041] Step S1: Mix N,N-dimethylaniline, p-hydroxyanisole, acrylic acid, and toluene until they are evenly mixed to prepare a drop solution, and add novolac epoxy resin to the reaction kettle, and set the temperature at 75°C Under the condition of stirring and adding dropwise liquid, dropwise adding time is 1h, after the dropping is completed, the temperature is raised at 85°C, and the reaction is carried out until the acid value in the reaction system reaches 0.5mgKOH / g, then the reaction is stopped , cooled to room temperature, the reactant was extracted 3 times with anhydrous ether to obtain a viscous substance, which was dried to obtain the first product;

[0042] Step S2: Add isophorone diisocyanate into the reaction kettle, add γ-aminopropyltriethoxysilane solution dropwise under the condition of an ice-water bath with a rotational speed of 60r / min, and react for 1 hour to obtain the second product , d...

Abstract

The invention disclsoes anti-aging EB floor and a preparation method thereof. The surface of a solid wood floor is coated with an EB coating through an electron beam immobilization technology, an anti-aging agent is prepared in the preparation process of the anti-aging EB floor, and when the anti-aging EB floor is illuminated, hydrogen bonds in the anti-aging agent are broken, so that a compound reaches an unstable high-energy state; when the anti-aging agent in the high-energy state needs to return to the low-energy state, heat release is needed, then light energy is converted into heat energy, and after the anti-aging agent returns to the low-energy state, hydrogen bonds in molecules of the anti-aging agent are formed again, so that the anti-aging agent can continuously consume the lightenergy, and the molecules of the anti-aging agent can decompose peroxides and generate nitroxide free radicals; the nitroxide free radicals can capture free radicals and quench singlet oxygen, so that the light stability of the polymer is enhanced, and the prepared EB floor is better in aging resistance.

Description

technical field [0001] The invention belongs to the technical field of floor preparation, and in particular relates to an aging-resistant EB floor and a preparation method thereof. Background technique [0002] Electron beam curing is an advanced material surface treatment technology that uses electron beam (EB) as the radiation source to induce a specially configured reactive liquid with a solid content of 100% to quickly transform into a solid. The incident electrons are bombarded and cured at approximately the speed of light. Material surface, strong penetrating power, curing is not affected by the color of the paint film, and can also cure the adhesive between the internal coating of paper or other substrates and opaque substrates, electron beam curing can make coatings, inks and adhesives 100% Curing, making electron beam curing has a good development prospect. [0003] The existing aging-resistant flooring will coat a layer of aging-resistant paint film on the surface...
