[0002] With the development of social science and technology and the improvement of living standards, organic polymer composite filling flame retardant materials have developed rapidly, and their output has increased year by year. Composite polymer materials have been widely used in building materials, decorative materials, wires and cables, electronic appliances, information and transportation.

[0003] Organic polymer composite filling flame retardant materials to achieve porcelain and flame retardant effects has developed into one of the new topics in flame retardant scientific research. In recent years, the market has attracted widespread attention to ceramic polymer composite materials in the field of passive fire protection. This material has the characteristics of low smoke, non-toxicity, and rapid transformation into ceramics under flame burning. It has very important economic significance, social benefits and theoretical research value for solving the fire resistance, flame retardancy and heat insulation problems of flame retardant polymers.

[0004] The surface temperature of the burning polymer material is 300-600℃, and strong thermal cracking occurs. When the polymer is heated to the thermal decomposition temperature, one or more of the following decomposition products are produced, such as combustible gases: methane, ethane, etc., such as non-combustible gases: carbon dioxide, water vapor, etc., such as liquids: usually partially decomposed plastics and high molecular weight organic compounds, such as solids: generally carbon-containing residues, such as charcoal or ash, such as solid particles and plastic fragments, which can form smoke. Obviously, when a fire is formed, the combustion process of polymer materials releases a large amount of smoke, which often causes great harm to the human body.

[0067] 3) adding solution A dropwise to mixed solution D to obtain mixed solution E, and then keeping mixed solution E at 90° C. for 6 h to obtain a crude product;

[0068] The crude product was cooled to room temperature, filtered, washed twice with deionized water, dried in a vacuum oven at 60°C, ground and sieved through a 150-mesh sieve to obtain zinc borate-coated tricalcium phosphate porcelain-forming powder.

[0069] 10 parts of PE resin, 40 parts of EVA resin, 0.05 parts of PE wax powder, 0.15 parts of antioxidant 168, 15 parts of low-melting-point glass powder and 35 parts of the ceramic powder prepared in Example 1 were weighed by mass and all were put into an internal mixer for blending. When the mixing temperature was raised to 160°C, the material was discharged after mixing for 15 minutes. After discharging, the material was processed by a flat vulcanizer at a processing temperature of 160°C, a processing time of 10 minutes and a pressure of 10 MPa to obtain a molding material.

[0070] The performance of the molding material prepared in Example 1 was tested, and the results are shown in Table 1.

[0071] Examples 2-4 and Comparative Example 1

[0072] The method of Example 1 is followed, except that different amounts of borax and zinc chloride are used, resulting in different ratios of zinc borate and tricalcium phosphate in the ceramic powder, as shown in Table 1.

[0073] The unexplained parts in Examples 2-4 and Comparative Example 1 are the same as those in Example 1.

[0074] The performance tests were performed on the molding materials prepared in Examples 2-4 and Comparative Example 1. The results are shown in Table 1.

[0075] Comparative Example 2

[0076] The method of Example 1 is followed, except that the same amount of tricalcium phosphate is used as the ceramic powder.

[0077] The unexplained parts in Comparative Example 2 are the same as those in Example 1.

[0078] The performance of the molding material prepared in Comparative Example 2 was tested, and the results are shown in Table 1.

[0079] Comparative Example 3

[0080] The method of Example 1 is followed, except that a physical mixture of zinc borate and tricalcium phosphate in the same amount is used as the porcelain-forming powder, as shown in Table 1.

[0081] The unexplained parts in Comparative Example 3 are the same as those in Example 1.

[0082] The performance of the molding material prepared in Comparative Example 3 was tested, and the results are shown in Table 1.

[0083] Table 1

[0084]

[0085]

[0086] It can be seen from Table 1 that the molding materials obtained in Examples 1-4 have a porcelain strength of more than 4.2 MPa after being kept at 950°C for 45 minutes. Under the condition of spraying with a butane spray gun for 5 minutes, the porcelain strength is as high as 3.5 MPa, and can reach a maximum of 5.5 MPa, which indicates that the molding materials prepared in the embodiments of the present invention have a low porcelain temperature and a short porcelain time.

[0087] It can be seen from Examples 1-4 and Comparative Example 1 that, under the condition that other conditions remain unchanged, when the mass ratio of zinc borate to tricalcium phosphate in the porcelain powder is (5-30):100, as the mass proportion of zinc borate continues to increase, the oxygen index and porcelain strength of the obtained molding material also gradually increase. However, when the mass ratio of zinc borate to tricalcium phosphate in the porcelain powder increases to 40:100, the oxygen index and porcelain strength of the molding material begin to decrease compared with Example 1.

[0088] By comparing Example 2 with Comparative Example 3, it can be seen that when the usage ratio of zinc borate to tricalcium phosphate is the same, compared with the physical mixing of zinc borate and tricalcium phosphate, the ceramic strength of the molding material can be significantly improved by chemically coating the zinc borate on the surface of tricalcium phosphate.

[0089] Figure 1 The SEM images of the ceramic powder prepared in Example 1 at different magnifications are shown; Figure 2 This is the SEM image of tricalcium phosphate in Comparative Example 2. Figure 1 and Figure 2 It can be seen that the surface of the ceramic powder of tricalcium phosphate coated with zinc borate is more uneven than that of the ceramic powder without coating;

[0090] pass Figure 3 It can be seen that the average size of the polymer added with the ceramic powder prepared in Comparative Example 3 after combustion is 58mm×6.2mm×5.8mm, and the average size of the polymer added with the ceramic powder prepared in Example 1 after combustion is 48mm×4.2mm×4.5mm. This indirectly indicates that after the polymer added with the ceramic powder prepared in Example 1 is burned, its interior is denser.

[0091] Example 5

[0092] The method of Example 1 is followed, except that tricalcium phosphate is replaced with the same amount of calcium silicate.

[0093] All parts not described in Example 5 are the same as those in Example 1.

[0094] The performance of the molding material prepared in Example 5 was tested, and the results are shown in Table 2.

[0095] Examples 6-8 and Comparative Example 4

[0096] The method of Example 5 is followed, except that different amounts of borax and zinc chloride are used, resulting in different ratios of zinc borate to calcium silicate in the ceramic powder, as shown in Table 2.

[0097] The unexplained parts in Examples 6-8 and Comparative Example 4 are the same as those in Example 5.

[0098] The performance tests were performed on the molding materials prepared in Examples 6-8 and Comparative Example 4. The results are shown in Table 2.

[0099] Comparative Example 5

[0100] The method of Example 5 is followed, except that a physical mixture of zinc borate and calcium silicate in the same amount is used as the porcelain-forming powder, as shown in Table 2.

[0101] The unexplained parts in Comparative Example 5 are the same as those in Example 5.

[0102] The performance of the molding material prepared in Comparative Example 5 was tested, and the results are shown in Table 2.

[0103] Table 2

[0104]

[0105] It can be seen from Table 2 that the molding materials obtained in Examples 5-8 have a porcelain strength of more than 3.5 MPa after being kept at 950°C for 45 minutes. Under the condition of spraying with a butane spray gun for 5 minutes, the porcelain strength is as high as 3.2 MPa, and can reach a maximum of 4.5 MPa, which indicates that the molding materials prepared in the embodiments of the present invention have a low porcelain temperature and a short porcelain time.

[0106] By comparing Examples 5-8 with Comparative Example 4, when other conditions remain unchanged, when the weight ratio of zinc borate to calcium silicate in the porcelain powder is (5-30):100, as the mass proportion of zinc borate continues to increase, the oxygen index and porcelain strength of the obtained molding material also gradually increase. However, when the mass ratio of zinc borate to calcium silicate in the porcelain powder reaches 40:100, the oxygen index and porcelain strength of the molding material begin to decrease relative to Example 5.

[0107] Figure 4 The cross-sectional diagram of the samples of the ceramic polymers of Example 6 and Comparative Example 5 after calcination; Figure 4 It can be seen that compared with the polymer filled with ceramic powder formed by physical mixing (Comparative Example 5), the ceramic polymer added with the ceramic powder prepared in Example 6 is denser inside after calcination, thereby being able to improve the compressive strength of the material.

[0108] After the molding material obtained in Example 6 was kept at 500°C for 45 minutes, its porcelain strength was 2.3 MPa; after the molding material obtained in Example 6 was kept at 750°C for 45 minutes, its porcelain strength was 3.2 MPa, indicating that the porcelain powder provided by the present invention can be formed into porcelain at 500°C.

[0109] Example 9

[0110] The method of Example 6 is followed, except that the amount of the porcelain-forming powder used is different, as shown in Table 3.

[0111] All parts not described in Example 9 are the same as those in Example 6.

[0112] The performance of the molding material prepared in Example 9 was tested, and the results are shown in Table 3.

[0113] Example 10

[0114] The method of Example 6 is followed, except that the amount of the porcelain-forming powder used is different, as shown in Table 3.

[0115] All parts not described in Example 10 are the same as those in Example 6.

[0116] The performance of the molding material prepared in Example 10 was tested, and the results are shown in Table 3.

[0117] Table 3

[0118]

[0119] It can be seen from Table 3 that when other conditions remain unchanged, as the amount of ceramic powder increases, the content of calcium silicate in the system increases at the same time, the oxygen index and ceramic strength of the polymer continue to increase, but the elongation at break of the polymer continues to decrease, and the tensile strength first increases and then tends to stabilize. Therefore, although increasing the content of ceramic powder in the resin-based composite material will improve the flame retardant properties and ceramic strength of the composite material, it will affect the mechanical properties of the composite material to a certain extent, and the addition ratio of ceramic powder needs to be controlled.
