Silicon calcium plastic corrugated composite paper board and preparation method thereof

Abstract

The invention discloses a silicon calcium plastic corrugated composite paper board, which is prepared by bonding silicon calcium plastic corrugated core paper and at least one layer of kraft paper, wherein the silicon calcium plastic corrugated core paper is prepared from the following raw materials including polyethylene, polycarbonate, calcium carbonate, kieselguhr, layered silicate, chitosan, coupling agents, antioxidants, plasticizers and zinc stearate. A preparation method comprises the following steps that all raw materials of the silicon calcium plastic corrugated core paper are mixed;the mixed material is guided into a banburying machine for banburying; after the mixed material is taken out, tableting is performed; next, sheet materials are subjected to open milling and tableting;after the cooling, the silicon calcium plastic corrugated sheet material is made into the silicon calcium plastic corrugated core paper on a corrugated roller; a bonding agent is coated on the silicon calcium plastic corrugated core paper; heating and curing are performed; the bonding layer is formed; then, the kraft paper is pressed on the bonding layer; the silicon calcium plastic corrugated composite paper board is manufactured. The corrugated paper board manufactured by the method has the excellent breaking-resistant intensity and bonding intensity and no tilting phenomenon, and can ensure excellent waterproof performance and anti-impact performance after obtaining the paper box product.

Description

technical field [0001] The invention belongs to the technical field of corrugated paper products, and in particular relates to a silicon-calcium-plastic corrugated composite cardboard and a preparation method thereof. Background technique [0002] Corrugated cardboard, also known as corrugated cardboard, is a cardboard made of multiple layers of materials bonded together. Corrugated cardboard is formed by bonding at least one layer of corrugated core paper (paper material or plastic material) and at least one layer of cardboard (kraft paper) in the middle. In terms of mechanical properties, it has very good ductility and elasticity, and very high mechanical strength, which can withstand falls and collisions during transportation, and is mainly used for carton products in packaging. The main performance of corrugated boxes in practical applications depends on the following three factors: 1. Core paper: corrugated core paper made of paper or plastic; 2. The characteristics of...

Problems solved by technology

[0003] Corrugated cardboard in the traditional sense is mainly composed of paper materials. Although this paper material has the characteristics of simplicity, convenience, and low temperature influence, and has excellent light resistance and shading performance, its moisture resistance and humidity resistance are relatively low. Poor, if this material is used in an environment with high humidity, its mechanical strength will be seriously affected
