Description
Technical field
The present invention relates to the preparation method of melamine resin, relate in particular to a kind of preparation method who is used to soak the melamine resin of woodgrained paper.
Background technology
Melamine plate, full name is a melamine-impregnated bond paper facing wood-based plate, it is the woodgrained paper that has different colours or texture to be put into melamine resin soak, be dried to certain state of cure then and make the melamine-impregnated bond paper, then melamine glue impregnated membranes paper is mated formation on the surface of substrates such as shaving board, medium density fibre board (MDF) or hardboard, form melamine decorative board through hot pressing.Melamine plate is not a product innovation, the gaudy not representative products of title is fresh, this kind sheet material is produced already at home, be to be used for doing office furniture such as computer desk at first, mostly be monochrome board, popular along with plate fitment in the family, it becomes the manufactured materials of each Furniture Factory's first-selection gradually, surface color and polish and decorative pattern are also more, and plate fitment in the market adopts import and homemade two kinds of sheet materials.Has very big fragility owing to soak the melamine-impregnated bond paper of back acquisition by existing melamine resin, therefore can only be on the planar substrate on the surface by hot pressing, can not be become on the undulatory substrate in surperficial continuous bend by hot pressing, cause the surface shape of existing melamine decorative board single, can not satisfy the demand of people the melamine decorative board profile.
Summary of the invention
The technical problem that the present invention solves is: a kind of preparation method of melamine resin is provided, and the melamine resin by this method manufacturing can soak into woodgrained paper the stronger melamine-impregnated glued membrane of plasticity.
Technical scheme of the present invention is: a kind of preparation method who is used to soak the melamine resin of woodgrained paper, it is characterized in that comprising following preparation process: 1) be that 37% formaldehyde joins in the reactor with 15～17 weight part concentration, and the adding alkali lye first time is in reactor, the pH value that makes solution in the reactor is 9～9.5, begin after stirring to heat up, after temperature reaches 35 ℃～45 ℃, the urea first time, the trimeric cyanamide of 3～5 weight parts and the polyvinyl alcohol of 0.5～1.5 weight part that add 3～3.5 weight parts, and fully stir;
2) continue to be warmed up to 85 ℃, and after being incubated 40～50 minutes, add the polyoxyethylene glycol of 0.4～0.5 weight part, and the adding alkali lye second time is in reactor, making the PH of solution is 7.5～8, when water smoke point occurring, adds the urea second time of 0.5～1 part of weight immediately; When the water Combination of solution reaches 1:2, add that alkali lye is in reactor for the third time, the pH value that makes solution in the reactor is 9～9.5;
3) industrial soft water that adds 3～5 weight parts cools off in reactor simultaneously;
4) when solution in the reactor is cooled to 60 ℃, adding 0.5～0.6 weight part concentration is 90% tenderizer;
When 5) solution is cooled to 40 ℃ in the reactor, discharging.
Further, the tenderizer described in the described step 4) is by polyvinyl alcohol, hexanolactam, the glycol ether of 1:2:3 are formed by weight percentage.
Further, the concentration of described trimeric cyanamide is 99%, and the concentration of described urea is 98%, and the concentration of described polyvinyl alcohol is 98%.
Further, described step 1) and step 2) described in alkali lye all be that concentration is 30% caustic soda.
Further, described formaldehyde is 16 weight parts, the urea first time that adds is 3.2 weight parts, trimeric cyanamide is 4 weight parts, polyvinyl alcohol is 0.985 weight part, and industrial soft water is 4 weight parts, and polyoxyethylene glycol has 0.45 weight part, the urea second time that adds is 0.8 weight part, and tenderizer is 0.52 weight part.
The invention has the beneficial effects as follows: woodgrained paper is by after the immersion of melamine resin, obtain the melamine-impregnated bond paper, melamine resin according to present method preparation can soak into woodgrained paper the higher melamine-impregnated bond paper of plasticity, this melamine-impregnated bond paper than high-ductility can cooperate the twisted plate face successive alternating bending of curved decorative plate, therefore can be fixed on the curved surface of curved decorative plate by hot pressing.
The main technical details of the melamine resin that preparation method of the present invention produced is as follows:
| Outward appearance | PH value | Viscosity | Proportion | The precipitating temperature | Adaptive phase | Shelf lives |
| As clear as crystal | 8.8～9.2 | Employing is coated with 4 glasss of measurements: 14-16 second | 1.16kg/m3 | 42℃ | 24 hours | 25～30 days |
Wherein, the survey instrument of viscosity adopts the QND-4 flow cup of source, Shenzhen side Instr Ltd., promptly is coated with 4 glasss.
