Definitions
- the invention relates to a borate intercalated hydrotalcite, and a preparation method and application thereof.
- Hydrotalcite (Layered Double Hydroxides, abbreviated as LDHs) has the property of intercalable layer assembly. Using this property, some functional species can be inserted between the layers of hydrotalcite to prepare supramolecular intercalation structure materials with special functions.
- the present inventor studied an ultra-fine, high smoke suppressing inorganic flame retardant and a preparation method thereof.
- the structure of the flame retardant is [Mg ⁇ A x (OH) 2 ] (C0 3 ) 2 - x / 2 m3 ⁇ 40, which is a layered structure, laminates hydroxides of Mg 2+ and Al 3+, the flame retardant is thermally decomposed during the release of C0 2 and 0 off endothermic cooling, dilution, isolated
- the flammable gas method plays a flame retardant role in the polymer substrate.
- the product after decomposition is an alkaline porous substance, which is larger than the surface and can adsorb harmful gases, especially acid gases. Therefore, it has good flame retardancy, but Smoke suppression performance is relatively poor.
- the purpose of the present invention is to make use of the intercalability of LDHs to insert borate into the interlayer of LDHs to prepare borate intercalated hydrotalcite.
- the intercalated hydrotalcite's smoke suppression performance is greatly improved.
- the borate ion partially or completely replaces co 3 2 between the hydrotalcite layers.
- the interlayer anion generated is borate and C0 3 2 -intercalated hydrotalcite, where 'borate accounts for 40-100wt% of the total anion, borate can be triborate or tetraborate alone or mixed The form exists between the layers of hydrotalcite.
- the hydrotalcite was compounded with PE, PVC, EVA, PP and various rubber materials, and the flame retardancy and smoke suppression tests were carried out.
- the flame retardancy was equivalent to that of LDHs flame retardants in patent application 02100800.
- the performance is greatly improved over LDHs. That is, the borate intercalated hydrotalcite is a high smoke suppression flame retardant.
- Table 1 shows the flame retardance and smoke suppression performance of different flame retardant and PE / EVA composites. Test results, where the mass ratio of PE to EVA was 90:10.
- Step A Dissolve 61.5 g (0.24 mol) of solid Mg (N0 3 ) 2 ⁇ 6H 2 0 and 45.0 g (0.12 mol) of solid A1 (N0 3 ) 3 9H 2 0 in 225 ml of 3 ⁇ 4; another 25.3 g (0.24mol) of solid Na 2 C0 3 and 23.0g (0.58mol) of NaOH were dissolved in 225ral water.
- the obtained Mg 2+ / Al 3+ 2: 1.
- Step B l.Og LDHs was added to a solution containing 40 ml of deionized water, and magnetically stirred at room temperature for later use.
- Step C Prepare an aqueous solution of H 3 B0 3 with a concentration of 1.5M and add it to the reactor with condensation and stirring. While stirring, add the solution obtained in step B dropwise. After the addition is complete, adjust the system with H 3 B0 3 aqueous solution.
- ⁇ 4.5, condensed and refluxed for 6 hours, filtered and washed to pH ⁇ 8, and dried at 100 ° C for 12 hours.
- the hydrotalcite was compounded with PE / EVA at a ratio of 70 parts by weight of a flame retardant per 100 parts by weight of PE / EVA material, and the limiting oxygen index 24.3 and the maximum smoke density of the composite material were measured. The results are shown in Table 1.
- the supramolecular structure boron-based semi-intercalated LDHs effectively exerted the synergistic effect of nano-LDHs and inorganic expanded flame retardants, while maintaining the good flame retardancy of nano-LDHs, and effectively improving the smoke suppression. Therefore, this flame retardant better overcomes the coexistence of LDHs and boron flame retardants.
- Step A Obtain the dispersed LDHs precursors according to steps A and B in Example 1.
- Step B Prepare an H 3 B0 3 aqueous solution with a saturated concentration of 1.6 and add it to the reactor with condensation and stirring. While stirring, add the solution obtained in step A dropwise. After the addition, use a saturated H 3 B0 3 aqueous solution. Adjust the pH of the system to 3.2, condense and reflux for about 2 hours, filter and wash to pH ⁇ 8, and dry at 70 ° C for 24 hours. The interlayer was assembled to obtain LDHs with complete intercalation structure of boric acid.
- the hydrotalcite was compounded with PE / EVA at a ratio of 70 parts by weight of flame retardant per 100 parts by weight of PE / EVA material.
- the limiting oxygen index of the composite material was 22.0 and the maximum smoke density was 67.2.
- the results are shown in Table 1 .
