The invention has the beneficial effects that:
the invention prepares the soft film by the film-forming reaction of aqueous polyurethane and aqueous isocyanate curing agent. The low volatility and the dissolving effect of the diethylene glycol butyl ether are utilized to promote the mixing of the raw materials, so that the reaction can be uniformly carried out, and the uniformity of the prepared shielding film layer is improved; by utilizing the coupling effect of tetra-n-propyl zirconate, one end of a molecule of the nano-barium sulfate can react with nano-barium sulfate to form a firm chemical bond, and the other end of the molecule can form electrostatic combination with waterborne polyurethane and polyethylene wax, so that the nano-barium sulfate is promoted to be filled into a macromolecular chain gap, and the film strength is improved; meanwhile, the water polyurethane, the diethylene glycol butyl ether and the polyethylene wax are promoted to be fully mixed and connected, so that the overall rheological property is improved, subsequent components can be better dispersed, and the film forming effect is better. The smoothness of the film body is improved by filling polyethylene wax, so that the prepared film is good in softness, and can be adhered according to the shape of corrugated paper, and the attaching degree of the shielding film layer and the supporting layer is better. Effectively isolated foreign matter and the contact of corrugated paper through the shielding rete, improve the anticorrosive effect of corrugated paper when promoting the corrugated paper performance.
According to the invention, the surface of the silicon rubber particles is corroded by using nitric acid with lower concentration, and the thermal resonance effect of microwaves is utilized, so that the chemical defects of the silicon rubber particles are enlarged, the rough surface is quickly formed, and the hydrophobicity of the silicon rubber is reduced. And promoting the insertion of waterborne polyurethane molecules into chemical defects on the surface of the silicon rubber particles, so that the waterborne polyurethane molecular chains are cemented and extended by taking the rubber particles as cores. The shielding film layer is crosslinked between the waterborne polyurethane molecular chains and the rubber particles and crosslinked between the waterborne polyurethane molecular chains, and the molecular configuration of the shielding film layer is enriched. The shielding film layer after the silicone rubber particles are filled has better elasticity, is not easy to be damaged by machinery, effectively protects corrugated paper, improves the environmental tolerance of the corrugated paper, and increases the strength of the corrugated paper. In addition, the silicon rubber particles with enough fineness are uniformly dispersed, so that the cementation of the shielding film layer can be maximally matched, the situation that the silicon rubber with finer particles is filled between molecular chains and cannot be effectively cemented can be prevented, and the problem that larger particles are not cemented completely can be solved.
According to the invention, through the use of the eucalyptus citriodora pulp, the characteristics of high viscosity brought by high holocellulose and rich pentosan in the eucalyptus citriodora pulp are utilized, the viscosity of the pulp composed of the raw materials of the supporting layer is improved, the surface modification of gamma-aminopropyltriethoxysilane and sodium dodecyl sulfate is carried out, the crosslinking degree is better in a system of polystyrene resin, polymethyl methacrylate, vinyl resin and polyethylene through amino coupling sisal fiber, coffee fiber, coconut fiber, acetate fiber and ethoxy coupling mineral fiber of the gamma-aminopropyltriethoxysilane, the bonding strength is stronger, the tightness of the supporting layer is strengthened, the mechanical property of the supporting layer is improved, and the corrosive substances penetrating through the shielding film layer are prevented from further permeating through forming a highly arranged molecular network. The corrosion resistance of the second stage is realized, and the weather resistance of the corrugated board is effectively enhanced by the echelon matching of the second stage and the shielding film layer.
The invention utilizes the chain crystal configuration of the sepiolite layer, has a large amount of Si-OH, can be polymerized with other organic components to form organic mineral derivatives, improves the integral molecular chain strength of the supporting layer, and the octahedral layer of the sepiolite layer forms channels arranged alternately on the upper layer and the lower layer, the orientation of the channels is consistent with the fiber axis, allows metal cations, organic micromolecules and the like to enter the channels, can be combined with ions released by the coffee fibers and the coconut fibers, further promotes other molecules to fill ion vacancies in the coffee fibers and the coconut fibers, enables the supporting layer to efficiently construct a reinforced molecular network to improve the strength of the corrugated paper, and increases the stability of the corrugated paper in different environments.
