Embodiment 1

[0035] In the embodiment of the present invention, high hygroscopic resins (i.e. SAP) of different qualities are added to the white latex to obtain adhesives with different mass contents of high hygroscopic resins, and the compressive shear dry strength and compressive shear wet strength of the adhesive are detected, and the results are shown in Table 1. shown. Wherein, the mass content of superabsorbent resin refers to the added amount of superabsorbent resin divided by the added amount of white latex. For example, 0.3% superabsorbent resin refers to the superabsorbent resin with 0.3% white latex added to the adhesive.

Embodiment 2

[0040] In order to improve the flow properties of the adhesive and increase the shear strength of the adhesive, the embodiments of the present invention introduce KH570 silane coupling agents with different mass contents to prepare the adhesive, and detect the compressive shear dry strength and compressive shear wet strength of the adhesive. Strength, the results are shown in Table 2. Wherein, the mass content of KH570 refers to the added amount of KH570 divided by the added amount of white latex, for example, 1% KH570 means KH570 with 1% white latex added to the adhesive.

[0043] It can be seen from Table 2 that the addition of KH570 silane coupling agent improves the flow...

Embodiment 3

[0045] The embodiment of the present invention introduces a silicone resin into the adhesive to enhance the waterproof performance of the adhesive and at the same time enhance the air permeability of the adhesive, so that the adhesive can be both waterproof and air-permeable, so that the moisture in the laminate floor can be discharged in time. In the present invention, silicone resins with different mass contents are added to detect the compressive shear dry strength and compressive shear wet strength of the prepared adhesive, and the results are shown in Table 3. Wherein, the mass content of the silicone resin refers to the added amount of the silicone resin divided by the added amount of the white latex. For example, 1% of the silicone resin means that 1% of the mass of the white latex is added to the adhesive.

Abstract

The invention discloses a moisture-proof treatment method for a reinforced wood floor, which comprises the following steps: mixing white latex and a superabsorbent resin to obtain an adhesive; coating the adhesive on the tongue and groove of the reinforced wood floor, laying the reinforced wood floor, so that the laminated wood floors are bonded and fixed by the adhesive. It can be understood that the technical solution of the present invention can adjust the humidity of the environment between the laminate flooring and the paving ground, thereby solving the problem that the laminate flooring is easily deformed under the condition of large changes in dryness and humidity inside and outside, and maintaining the humidity of the laminate flooring The internal dry and humidity balance prolongs the service life of the laminate flooring.

Description

technical field [0001] The invention relates to the technical field of building decoration materials, in particular to a moisture-proof treatment method for laminate flooring. Background technique [0002] Laminate flooring, originated in Europe, is a new type of floor based on wood-based panels. It is generally divided into two categories: laminate flooring based on medium and high-density fiberboards and laminate flooring based on shavings. , It is widely used in the ground laying of family rooms, conference halls in public places, dance halls, hotels and other places. White latex, that is, polyvinyl acetate emulsion adhesive, has the characteristics of high bonding strength, fast curing rate, long storage period, convenient use, and low price. It is widely used in floor tongue and groove glue; The environment is easy to open glue. [0003] The poor waterproof performance of laminate flooring and the high expansion rate of water absorption thickness have always been insu...
