Benefits of technology

This patented method uses two stages: one involves adding certain chemical agents (nanosized or small) called silanes coupled agents onto the surface layer of papermaking felt before making it up the final sheet material used for environmental conservation purposes. These chemistries help increase the strength and durability of the finished environmentally friendly products while reducing their negative impact upon human health caused by harmful substances such as formaldehyde emissions. Overall, this new technique enhance the quality control and efficiency of manufacturing environments' worthiness.

Problems solved by technology

This patented technical solution describes how highly durable colored bases are needed when producing ecotical products like wood or planking. These colors should provide good visual appeal while being able to absorb harmful chemical substances from plants without causing damage over time. Additionally, these colorings require specific conditions at certain stages throughout their manufacturing process. Existing solutions involve expensive methods involving complicated steps and often result in poorly designed palettes on top surfaces.

Abstract

The invention discloses special ecological board decoration base paper and a preparation method thereof. The special ecological board decoration base paper comprises paper pulp, composite fillers andmulti-component retention agents, the paper pulp comprises whitened broadleaf wood sulfite pulp, whitened coniferous wood sulfate pulp, whitened broadleaf wood chemi-mechanical pulp and waste stuff, the composite fillers comprise modified nano-titanium dioxide, kaolin and talcum powder, and the multi-component retention agents comprise cationic polyacrylamide, silica solution and bentonite. By theaid of a staged filling technique, at a first stage, titanium dioxide is modified, and the modified titanium dioxide is added into a hydrapulper in the pulping process. At a second stage, the composite fillers such as the titanium dioxide, the kaolin and the talcum powder are dispersed by a high-speed dispersion machine, and the dispersed composite fillers are added into an approaching system. The filling quantity of the decoration base paper reaches 50% or more, and the ash content of the decoration base paper reaches 40% or more. The special ecological board decoration base paper has the advantages of high ash content, good covering performance and strength, sun resistance, environmental protection and the like and has a wide market prospect.
