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 fire-retardant cyanurotriamide modified urea resin floor glue of low aldehyde 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 has overcome the shortcoming of solid wooden floor board moisture expansion and drying shrinkage, there is good dimensional stability, natural wood veins and the comfortable feel of solid wooden floor board have been retained simultaneously, thereby become the important kind in floor, produce the also lifting thereupon of urea-formaldehyde resin bottom plate glue consumption that solid wooden compound floor uses.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 existing 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 present invention's object, be achieved by the following technical solutions: the fire-retardant cyanurotriamide modified urea resin floor glue of a kind of low aldehyde, this bottom plate glue is counted by weight and is comprised following component:
350 parts, formaldehyde;
160 parts, urea;
100 parts of trimeric cyanamides;
5 parts of polyvinyl alcohol;
Fire retardant A5-10 part;
Fire retardant B10-20 part.
As preferred version: described fire retardant A is ammonium polyphosphate; Fire retardant B is triethyl phosphate; 8 parts of ammonium polyphosphates, 15 parts of triethyl phosphates.
The present invention also provides a kind of preparation method of above-mentioned floor glue, comprises the following steps: being equipped with in the there-necked flask of electric stirring, thermometer, add the formaldehyde, urea, the polyvinyl alcohol that measure; Adding appropriate concentration is 30% liquid caustic soda, adjusts pH value to 8.5, is warming up to 90 ℃, is incubated 1 hour; After insulation finishes, add formic acid, adjust pH value to 5.0, viscosimetric, in the time that viscosity reaches 22-25Pas, adding concentration is 30% liquid caustic soda, adjusts pH value to 9.5-10, adds the trimeric cyanamide, the fire retardant A that measure, is incubated 1 hour at 85-88 ℃, cooling, adds fire retardant B, stirs, and obtains 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.Prepared product according to LY/T 1738-2008 tested that its dipping is peeled off, MOR, free formaldehyde and tested its oxygen index according to GB/T 2406-93.
| ? | Dipping is peeled off | 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 that uses the fire-retardant cyanurotriamide modified urea resin floor glue of this low aldehyde to produce has better MOR and lower burst size of methanal.And its oxygen index is higher, there is good flame retardant effect.
