Description

Wax sealing agent for mortises of laminate flooring and preparation method of wax sealing agent

(I) technical field

The invention relates to a wax sealing agent capable of generating air negative oxygen ions and a preparation method thereof, which can be applied to tongue-and-groove wax sealing of laminate flooring to enable the laminate flooring to generate the air negative oxygen ions, and belongs to the field of manufacturing of functional health floors.

(II) background of the invention

In recent years, with the development of economy in China, the housing conditions of residents are remarkably improved. The rise of the housing industry provides a huge market space for the development of the decorative material industry. Among them, the use of wood flooring represented by a laminate flooring has been popular. It has two major problems. Firstly, the laminate flooring needs to be subjected to a glue dipping (generally melamine formaldehyde glue) process in the manufacturing process, so that the flooring can slowly release formaldehyde to pollute the indoor air environment; secondly, the existing wooden floor is easy to be affected with damp, mildewed and discolored, and further a great amount of harmful bacteria are bred. With the enhancement of environmental protection and health awareness of people, the single-function reinforced floor is not favored by the public, and the market urgently needs to provide a health floor which has moisture resistance, antibiosis and health care function.

From the structural point of view, laminate flooring is generally composed of four layers of materials, i.e., wear-resistant paper, decorative paper, high density substrate board, and balance paper. The main manufacturing process comprises the following steps: firstly, performing gum dipping treatment on wear-resistant paper, decorative paper and balance paper; secondly, sequentially covering the decorative paper layer and the wear-resistant paper layer which are subjected to gum dipping treatment on the front side of the high-density substrate board, and covering the balance paper layer on the back side of the high-density substrate board; then carrying out hot-press molding; and finally, carrying out the steps of curing, plate cutting, mortise opening, transfer printing, wax sealing and the like. After the floor is laid and installed, the bottom surface of the floor is the place which is most easily affected with damp and grows mildew, the mortise gap is the only channel for connecting the bottom surface of the floor with indoor air, and the mortise gap has a relatively large contact area with the air; on the other hand, the mortise is the place which is most easy to fall into dirt, residual water vapor and generate germs.

At present, medical research shows that the content of negative ions in the air has a close relationship with human health, and the following table shows that:

TABLE 1 relationship between the concentration of negative ions in the environment and the health of the human body (reported in International journal of medicine)

As can be seen from table 1, the concentration of negative ions in the air in the enclosed spaces such as houses and offices is far from the basic requirement for maintaining human health. Because most of the time of people spend indoors, the quality of indoor environment directly affects the health of people, and the floor used for laying indoor floor occupies a larger indoor area, if an additive capable of generating air negative oxygen ions is introduced into the floor, the floor has the function of releasing the air negative ions, and is certainly popular with consumers.

Tourmaline (tourmaline) is a boron-containing cyclic silicate mineral with additional anions and has SiO as main chemical component₂、Fe₂O₃、B₂O₃，、A1₂O₃、Na₂O、MgO、Li₂O、MnO₂And the like. In 1989, Japanese scholars Kubo firstly discovered the unique phenomenon that tourmaline has permanent electrodes, and developed a series of researches on the electric field effect of tourmaline micropowder. According to Kubo theory, tourmaline has permanent electrode and reacts with water molecules to ionize the water molecules to generate OH^-And H⁺。H⁺Will form hydronium ion (H)₃O⁺) Or form H₂，OH^-Combined with water molecules to form (H)₃O₂)^-，(H₃O₂)^-The air negative ions are emitted into the air. If moisture in the air, sweat of human body and other water molecules contact tourmaline, the above reaction will also occur, and negative ions will be generated to enter human body. Therefore, the necessary condition for generating the negative ions in the air around the tourmaline lies in that the tourmaline crystal is fully contacted with the air, namely when the tourmaline powder is coated on a certain surface, the tourmaline coating has certain air permeability, and a channel is provided for the diffusion of the generated negative ions.

In conclusion, in order to promote the tourmaline to better exert the function of releasing negative ions, the larger the contact area between the tourmaline and the air, the better the contact area is, and enough water molecules are ensured to be arranged on the contact surface. It has been found that after installation of the floor, the underside of the floor is the most susceptible to moisture and mold growth, and the tongue and groove gap is the only path connecting the underside of the floor to the room air where there is a relatively large amount of contact area with the air. Therefore, in structural view, the tourmaline negative ion powder is introduced into the mortise gap, so that the requirement of the contact area can be met. The strengthened floor is further subjected to wax sealing treatment after the mortice is opened, so that the tourmaline is added into the molten wax solution, and after the wax sealing treatment, the tourmaline can be uniformly coated on the surface of the gap between the strengthened floor and the mortice to be fully contacted with the air, and the negative ion release function is promoted.

After tourmaline is introduced into the paraffin liquid (1-3 percent)Accounting for the mass of paraffin), the release concentration of the negative ions of the product reaches or exceeds the level of a city park (1000-2000/cm)³) (ii) a When the addition amount of the tourmaline reaches 3 percent, the product even reaches the level (5000-50000 pieces/cm) close to the suburb and field³). As can be seen from the test results of the example 3 and the comparative example 3-2, the introduction of the super absorbent resin can greatly promote the anion release capacity of the tourmaline under the same tourmaline addition amount, thereby greatly improving the anion release concentration of the product.
