Embodiment 1

[0027] combine image 3 This embodiment is described in detail, and it is characterized in that: the surface layer is flexible veneer composited with basswood sliced ​​veneer and non-woven fabric; 2 and melamine resin mixture impregnation-precuring-curing treatment, glued and fixed to the core layer, the surface surface does not need to be painted; 1) the surface layer of basswood composite flexible veneer is impregnated with melamine resin, which is impregnated by normal temperature and pressure impregnation process Realization, the dipping amount is 100%, the pre-curing degree is 25%, and the flexible veneer impregnated with melamine resin is glued to the core poplar veneer. Realized by the pressure of 1.2MPa.

[0028] 2) High-quality basswood flexible veneer impregnated with melamine resin. The melamine resin used for impregnation adopts a self-developed low-temperature curing melamine adhesive for impregnation. The composition of the melamine adhesive is formaldehyde, mel...

Embodiment 2

[0032] like Figure 4 As shown, the surface layer is flexible veneer composited with basswood sliced ​​veneer and non-woven fabric, and the flexible veneer has not been impregnated with melamine resin solution. Gluing the surface flexible veneer to the core requires the application of adhesive. The core layer and the non-woven fabric of the flexible veneer surface layer not impregnated with melamine resin are coated with isocyanate adhesive, and are glued and fixed together by hot pressing at a temperature of 95°C, a hot pressing time of 60s, and a unit hot pressing pressure of 0.4MPa. Antibacterial materials loaded with silver nano-TiO 2 Added to the paint for finishing, in which silver-loaded nano-TiO 2 The ratio with the paint mass is 1:100.

Embodiment 3

[0034] For the flexible veneer treated by impregnation on the surface, the amount of impregnation reaches 200% by multiple dipping treatments, and the pre-curing treatment process is adjusted to achieve a pre-curing degree of 35%. The surface basswood flexible veneer impregnated with melamine resin is a self-developed low-temperature curing impregnated melamine adhesive. The flexible veneer used in the experiment is realized by the self-developed composite reinforcement technology of veneer and non-woven fabric. Since the surface layer of flexible veneer is impregnated with melamine resin adhesive, the composition of the melamine adhesive is formaldehyde, melamine, urea, and water, and its mass ratio is 6:3:3:1; 240s, unit hot pressing pressure 2.0MPa hot pressing process, so that the surface layer and the core layer are directly glued together.

[0035] Antibacterial material silver-loaded nano-TiO 2 Added to the impregnated melamine resin adhesive in a mass ratio of 1:50 to...

Abstract

The invention relates to a preparation method for a slat of an antibacterial compound shutter. The preparation method is characterized in that the slat of shutter comprises a sandwich layer and a surface layer, wherein the sandwich layer adopts a fast-growing poplar sliced veneer; the surface layer is a flexible veneer formed by compounding a basswood sliced veneer and a piece of non-woven fabric; the flexible veneer of the surface layer is divided into two types: the first type is as follows: a mixed liquor of silver-loaded nano TiO2 and melamine resin performs dipping-precuring-curing process on the flexible veneer of the surface layer, then, the flexible veneer is fixed on the sandwich layer in a glue joint manner, and the surface of the surface layer requires no coating process; the other type is as follows: a formaldehyde-free isocyanate adhesive is smeared on one side of the non-woven fabric of the flexible veneer of the surface layer, through the curing process, the flexible veneer of the surface layer is fixed on the sandwich layer in a glue joint manner, and the surface of the surface layer requires coating process. According to the invention, the consumption of the high-quality basswood is reduced, the product cost is reduced, and the additional value is increased; in addition, the silver-loaded nano TiO2 is compounded with the veneer of the surface layer is realized during the preparation process, the excellent antibacterial efficacy is provided for the slat of the shutter, the rate of multipurpose utilization of timber resources is increased, the purpose of improving performances is realized, and the demands of functionality and individualized products from the market are met.

Description

technical field [0001] The invention relates to a preparation method of an antibacterial composite shutter blade, in particular to a processing method of a three-layer composite shutter blade, belonging to the field of home decoration. Background technique [0002] Timber is one of the indispensable important resources in national economic construction and people's daily life. Among the four major construction materials of cement, steel, wood, and plastic, wood is the only renewable circular economy material. With the construction and development of the national economy, the timber gap will further increase, and the contradiction between timber supply and demand and environmental protection will become more prominent. In recent years, many countries have strictly restricted the export of timber due to the pressure of environmental protection, the demand for value-added industrial log processing, and the development of their own economies, and their prices have continued to ...
