Abstract
The invention discloses low-aldehyde flame retardant tripolycyanamide modified urea-formaldehyde resin floor glue which comprises the following components in parts by weight: 350 parts of formaldehyde, 160 parts of urea, 100 parts of tripolycyanamide, 5 parts of polyvinyl alcohol, 5-10 parts of a flame retardant A and 10-20 parts of a flame retardant B. The preparation method comprises the following steps: adding metered formaldehyde, urea and polyvinyl alcohol into a three-mouth bottle provided with an electric stirrer and a thermometer; adding a proper amount of caustic soda liquid with the concentration of 30%, adjusting the pH value to 8.5, heating to 90 DEG C and insulating for 1 hours; and after insulating, adding formic acid, adjusting the pH value to 5.0, measuring the viscosity, adding 30% caustic soda liquid when the viscosity reaches 22-25Pa.s, adjusting the pH value to 9.5-10, adding the metered tripolycyanamide and the flame retardant A, insulating for 1 hour at 85-88 DEG C, cooling, adding the flame retardant B, and uniformly stirring to obtain a product. The floor glue is excellent in flame retardance and low in formaldehyde emission.
Description
Technical field
The invention belongs to adhesive area, be specifically related to low aldehyde flame melamine modified urea-formaldehyde resin floor glue and preparation method thereof.
Background technology
Along with the rapid development of China's economic, the raising of living standards of the people, the requirement of house decoration is also constantly improved.Timber floor, because of its naturally graceful lines, good texture, becomes the preferred material of family's ground surface finishing.And solid wooden compound floor overcomes the shortcoming of solid wooden floor board moisture expansion and drying shrinkage, there is good dimensional stability, remain the natural wood veins of solid wooden floor board and comfortable feel simultaneously, thus the important kind become in floor, the urea-formaldehyde resin bottom plate glue consumption that production solid wooden compound floor uses also promotes thereupon.Existing floor glue does not have flame retardant properties, and burst size of methanal is larger.
Summary of the invention
Technical problem to be solved by this invention is: the deficiency existed for prior art, and provide a kind of flame retardant properties good, burst size of methanal is low, is beneficial to cyanurotriamide modified urea resin floor glue strengthening solid wood base plate base material MOR and preparation method thereof.
For realizing the object of the present invention, be achieved by the following technical solutions: a kind of low aldehyde flame melamine modified urea-formaldehyde resin floor glue, this bottom plate glue is counted by weight and is comprised following component:
350 parts, formaldehyde;
160 parts, urea;
Trimeric cyanamide 100 parts;
Polyvinyl alcohol 5 parts;
Fire retardant A5-10 part;
Fire retardant B10-20 part.
Preferably: described fire retardant A is ammonium polyphosphate; Fire retardant B is triethyl phosphate; Ammonium polyphosphate 8 parts, triethyl phosphate 15 parts.
The present invention also provides a kind of preparation method of above-mentioned floor glue, comprises the following steps: in the there-necked flask that electric stirring, thermometer are housed, and adds the formaldehyde, urea, the polyvinyl alcohol that measure; Add the liquid caustic soda that appropriate concentration is 30%, adjust pH value to 8.5, be warming up to 90 DEG C, be incubated 1 hour; Add formic acid after insulation terminates, adjust pH value to 5.0, viscosimetric, when viscosity reaches 22-25Pas, add the liquid caustic soda that concentration is 30%, adjust pH value to 9.5-10, add the trimeric cyanamide, the fire retardant A that measure, 85-88 DEG C of insulation 1 hour, cooling, adds fire retardant B, stirs, obtain product.
Compared with prior art, the invention has the beneficial effects as follows: flame retardant properties is good, burst size of methanal is low.For investigating the performance of floor glue of the present invention, by this sizing agent with common sizing agent for the production of solid wooden compound floor base material.Thickness is 15mm.Obtained product tests its dipping and stripping, MOR, free formaldehyde according to LY/T 1738-2008 and tests its oxygen index according to GB/T 2406-93.
| Dipping and stripping | MOR | Burst size of methanal | Oxygen index | |
| This floor glue | Nothing | 39 | 0.3 | 39.9 |
| General floorings glue | Nothing | 31 | 1.5 | 25.8 |
Experimental result shows, the solid wooden floor board base material using this low aldehyde flame melamine modified urea-formaldehyde resin floor glue to produce has better MOR and lower burst size of methanal.And its oxygen index is higher, there is good flame retardant effect.
