Bio-based scratch-resistant type flame-retardant wallpaper base paper and preparation method thereof

Abstract

The invention discloses bio-based scratch-resistant type flame-retardant wallpaper base paper. The bio-based scratch-resistant type flame-retardant wallpaper base paper is an improvement of a prior process and a prior formula, and is obtained by the steps of: taking sepiolite powder, antimony trioxide and chlorinated paraffin as flame retardants, and performing modification; capturing H- and OH- free radicals for maintaining a chain reaction of combustion in a paper combustion reaction gas phase to change a reaction pattern in the gas phase; and reducing reaction heat release to quench flames. Meanwhile, organically modified nano silicon carbide is added into raw materials, so that the brushing property and scratch resistance of the base paper are improved, and the base paper can be closely combined with a decorative layer and cannot fall off easily. The flame resistance of the flame-retardant wallpaper base paper prepared according to the invention reaches a GB / T14656-93 requirement, and the tear strength, folding strength, ring crush strength and tensile strength of the base paper are improved.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a bio-based scratch-resistant flame-retardant wallpaper base paper and a production method thereof. Background technique [0002] Wallpaper, also known as wallpaper, is based on paper, non-woven fabric or woven fabric, plus a decorative layer, and is widely used for some wall or wall decoration. Although wallpaper is not essential for the decoration of buildings, it is already an important means of creating interior style, atmosphere and color. In particular, paper-based wallpapers are favored by people no matter in terms of product performance or environmental protection requirements. [0003] Paper is an essential item in people's lives. With the development of social economy, paper and paper products are widely used in many aspects such as packaging materials, building materials, industry and agriculture, and daily necessities. The ignition point of paper is between 130...

Problems solved by technology

[0005] This paper only analyzes the flame retardancy of the base paper. However, the current wallpapers generally have problems such as easy to accumulate dust and dirt, get wet when exposed to water, poor sound insulation effect, and single function. It is less than the technical indicators that people have high requirements for the indoor environment, and it will become moldy in humid areas or humid climates, especially during the rainy season in the south, which is not easy to store and has a short service life. This requires frequent replacement of wallpaper, and the cost is high
