oC, the reaction times is 4 h, cooling gets magnalium phosphate composite bonding agents base-material, the phosphoric acid add-on is [Mg, Al]: [P]=0.5, wherein, [Mg, Al] is the mole number sum of aluminium in the mole number of magnesium in the sepiolite and the malthacite, and [P] is the mole number of phosphorus in the phosphate aqueous solution;
4) magnesium oxide of adding base-material massfraction 5 % in magnalium phosphate composite bonding agents base-material makes the magnalium phosphate composite bonding agents.
Performance test: with the binding agent room temperature, leave standstill for some time, observe stability; The solidifying agent that adds binder content 40 %, casting in the steel die of 20mm * 20mm * 20mm, vibration is to get rid of micro-bubble, and the room temperature maintenance is tested its ultimate compression strength to solidifying fully; Sample after solidifying is placed 24h in humidity is the environment of RH90 %, takes out the ultimate compression strength of measuring after its moisture absorption, the intensity after the moisture absorption and the ratio of former intensity represent the size of resistance to water soak.
Table 1: each example prepares the performance test results of binding agent
| ? | Stability/day | Resistance to water soak/% | Ultimate compression strength/Mpa |
| Example 1 | >30 | >80 | 56.4 |
| Example 2 | >30 | >80 | 63.6 |
| Example 3 | >45 | >85 | 62.1 |
