Accompanying drawing explanation
Fig. 1 is reinforced composite floorboard and the schematic diagram of surface wet-heat resisting structure；
Fig. 2 is the processing process figure of wet-heat resisting spraying dipping paper.
Detailed description of the invention
Below in conjunction with the accompanying drawings presently preferred embodiments of the present invention is described in detail, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, thus protection scope of the present invention is made apparent clear and definite defining.
Referring to attached Fig. 1 and 2, the embodiment of the present invention includes:
A kind of reinforced composite floorboard surface wet-heat resisting solution, the surface pressing wet-heat resisting at reinforced composite floorboard sprays dipping
Paper；Wet-heat resisting spraying dipping paper includes facing paper basic unit, resin bottom and wear-resisting compound tree lipid layer, resin surface layer；Resin bottom
It is coated on the lower surface of facing paper basic unit；The upper surface of facing paper basic unit coats wear-resisting compound tree lipid layer；At wear-resisting compound tree
Vertical top layer it is coated with in lipid layer；The composition of wherein said wear-resisting compound tree lipid layer includes: carborundum, aluminium sesquioxide and MF tree
Fat；Guaranteeing that MF resin wraps aluminium sesquioxide, because can not there be the gentle bubble of hole at the interface of both materials, no side pressure goes out ground
Just turn white in plate surface.Even if the dipping paper that we produce overlays non-whitening under normal circumstances, but under conditions of damp and hot, hot water
The interface of MF and aluminium sesquioxide will be broken through, form bubble and hole, turn white so floor surface is formed.
Prepare above-mentioned wet-heat resisting spraying dipping paper production method, its processing step includes successively: uncoiling, the back of the body painting, impregnation,
Liquid spray, put down, first drying, coating, secondary drying, shearing, stacking, packaging；In liquid spray with coating process, adopt
Use MF resin.Being different from common conventional pickling process, the production method of this wet-heat resisting spraying dipping paper is a kind of revolutionary
Dipping technique.By cement dipping machine, general decor paper is carried out the back of the body and be coated with gluing, impregnation, liquid spray, coating so that facing paper basic unit
Lower surface scribble resin bottom, the upper surface of facing paper basic unit scribbles wear-resisting compound tree lipid layer, resin table the most successively
Layer, wear-resisting compound tree lipid layer is mixed group by the ceramic material of the high-wearing feature such as carborundum, aluminium sesquioxide with melmac
Become.
Temperature and wind speed that first drying and secondary drying are used are the most different, and conventional impregnation uses the low wind speed of high temperature
Technique, and this production method uses low temperature high wind speed drying curve.Its contrast is such as following table:
Liquid spray, with coating process, uses MF resin, and this MF resin includes virgin rubber, latent curing agent, penetrating agent, the demoulding
Agent；Being modulated into of MF resin point includes virgin rubber, latent curing agent, penetrating agent, releasing agent.The addition of latent curing agent with
Hardening time is as the criterion, the hardening time of MF resin be 4 points 30 seconds ~ 4 points 40 seconds, in MF resin, the addition of penetrating agent is gross mass
0.2%, in MF resin, the addition of releasing agent is also the 0.2% of gross mass.Latent curing agent selects our company 2013
The CA010 latent curing agent developed voluntarily, reaches the effect of higher latency.This latent curing agent is for impregnating the life of paper
Produce, be not only greatly improved the storage phase of dipping paper, and impregnate paper when the later stage overlays to overlaying the adaptability of temperature significantly
Strengthen.
The composition of virgin rubber and the quality of each composition are as follows:
Formaldehyde 1000kg；
Tripolycyanamide 850kg；
Water 450kg；

Value is adjusted to 9.0 ~ 9.5；
2, heat up after adding the tripolycyanamide of 850kg in above-mentioned mixed solution, be warming up to 90 ~ 92 DEG C and be incubated；During insulation
Measure pH value, if pH value less than 9.0, then adjusts the Acidity of Aikalinity of now solution and to control pH value be 9.0；
3, the solution in insulating process is in the stage of reaction, the pH value measuring the most now solution in each 10 minutes, and keeps this
Time solution pH value be not less than 8.5, temperature retention time is 120 minutes；
4, the solution after insulation is placed in reactor and is cooled to glue, determine water-soluble multiple when cooling and cloud point: putting
During glue, water-soluble multiple is adjusted to (1:1.5 ~ 1.6)；When cooling, terminate reaction with Caustic soda and the pH value of glue is adjusted to
9.0~9.5；
5, after the glue that the 4th step obtains being cooled to 60 DEG C, add 60kg caprolactam and stir, it is ensured that now glue
The pH value of water is 9.0 ~ 9.5；
6, the glue that the 5th step obtains is cooled to 40 DEG C and i.e. obtains described virgin rubber.
The spread of this virgin rubber is 130 ~ 140%, and fugitive constituent is 5.0 ~ 5.5%, and procuring degree is 55 ~ 70%.
This wet-heat resisting spraying dipping paper solves the requirement on user's high gloss floor, and other indexs of the floor of extrusion meet
GB/T 18102-2007(" impregnated paper laminated wood floor " GB) requirement；
This wet-heat resisting spraying dipping paper spread is 220-240%, and volatilization is divided into 6.5-7.2%, and procuring degree is 40-50%, other
Index meets GB/T28995-2012(" wood-based plate dedicated paper " GB) regulation.
The foregoing is only embodiments of the invention, not thereby limit the scope of the claims of the present invention, every utilize this
Equivalent structure or equivalence flow process that bright description is made convert, or are directly or indirectly used in other relevant technology necks
Territory, is the most in like manner included in the scope of patent protection of the present invention.
