The reinforcing agent includes nano grade titanium white powder, jute staple fiber, the weight of the meter level titanium dioxide and jute staple fiber
Amount part is compared for 3~5:8~10.
The dipping solution be paraffin oil, the thermoplastic acrylic resin by n-BMA monomer polymerization and
At the coupling agent is vinyl front three oxosilane.
A kind of preparation method of the freeze proof maceration extract of corrugated case waterproof, should the preparation method comprises the following steps: by each raw material in 100~
3~5min is mixed in required ratio at 110 DEG C.
A kind of application method of the freeze proof maceration extract of corrugated case waterproof, the application method are as follows: prior at 100~110 DEG C
Corrugated board is placed in the maceration extract 5~10s of dipping, then will complete the corrugated board after dipping at 110~130 DEG C into
Row heat is dried, and finally cools down 20min or more at room temperature.
The principle of the present invention is described as follows:
The invention proposes a kind of maceration extract for corrugated case, the maceration extract and corrugated case can directly be formed compared with
Strong chemical bond forms firm enhancing protective layer in corrugated case surface cure rapidly, even if so that corruggted wrapping case is long
Phase is in cryogenic freezing environment, its intensity will not be substantially reduced in soaking conditions in water, and non-volatile object pollutes, and can be used for cold
Freeze the packing and storing of product under transport product packaging, low temperature and moisture environment, it is also possible to ship live fish, marine product and water content pole
High class I goods.In addition, the maceration extract is clear, colorless thick liquid, it is impregnated in the color of back cardboard on corrugated board not
It can change, therefore not influence the overall appearances such as the pattern of body paper case, decorative pattern.
Impregnate solution: paraffin oil can reduce the viscosity of solution, enable jute staple fiber more as dipping solution after heating
It is uniform impregnated, meanwhile, paraffin also has waterproof, moisture-proof role, asepsis environment-protecting.
Thermoplastic acrylic resin: being polymerized by monomer methacrylic acid N-butyl, is had good elastic and higher
Gluing.
Modifying agent: ethylene-propylene diene copolymer, ethylene-vinyl acetate copolymer are the good modified material of low temperature flexibility, the two
The flexibility of waterproof membrane can be enhanced, increase waterproof film strength, be destroyed cardboard waterproof membrane in folding process not, increase simultaneously
The waterproof performance of strong waterproof membrane.In addition, also having using ethylene-vinyl acetate copolymer as waterproof membrane made from modifying agent molten
The advantages that melt-viscosity is low, cohesive force is high, cold resistance is high, but its softening point, hardness and strength are relatively low, and therefore, the present invention will
Ethylene-vinyl acetate copolymer is shared with ethylene-propylene diene copolymer, to make up above-mentioned deficiency.
Nanometer titanium dioxide: being a kind of non-toxic and tasteless free of contamination inorganic matter for unformed white powder.Its surface molecular shape
Three-dimensional netted structure is presented in state, can form network structure when waterproof membrane is dry after addition, dramatically increase waterproof film strength；
The ultraviolet radiation absorption effect for increasing cardboard, to improve the weatherability of cardboard, scratch resistant；Significantly improve the ageing resistance of waterproof membrane
Energy, finish；Guarantee fiber impregnation more evenly.In addition, it also has sterilization, the mould proof of corrugated case can be met
Performance requirement.
Jute staple fiber: the present invention uses very environmentally friendly jute staple fiber, and not only intensity is high, and length generally exists
400~900 μm, which is more suitable for impregnating.
Heat is dried: the solidification that can accelerate maceration extract using heat baking in application method of the present invention is qualitative, makes the smooth circle of paperboard surface
Whole, dipping is uniform.
