Wherein the flame retardant is a borate; the reinforcing filler is talcum powder; the ultraviolet-resistant auxiliary agent consists of UV-360 and thiodipropionate in a weight ratio of 3: 2; the anti-aging agent is RD; the coupling agent is a titanate coupling agent; the plasticizer is D810; the lubricant is ZG 16.
Performance testing
The polyvinyl chloride foamed sheets prepared in examples 1 to 4 and comparative examples 1 to 2 were respectively tested for performance tests, and the specific data were compared as follows:
| numbering | Smooth finish Ra | Density g/cm3 | Shore hardness HD | Coefficient of linear thermal expansion (10-6 m.DEG C.)-1) |
| Example 1 | Less than 0.4 | 0.35 | 58 | 33.9 |
| Example 2 | Less than 0.4 | 0.33 | 55 | 30.7 |
| Example 3 | Less than 0.4 | 0.34 | 56 | 31.2 |
| Example 4 | Less than 0.4 | 0.34 | 57 | 32.6 |
| Comparative example 1 | Greater than 3.2 | 0.42 | 40 | 83.1 |
| Comparative example 2 | Greater than 3.2 | 0.45 | 38 | 85.7 |
As can be seen from Table 1, the polyvinyl chloride foam board of the present application has a lower product density and a higher Shore hardness, and simultaneously, the linear thermal expansion coefficient of the prepared polyvinyl chloride foam board is greatly reduced.
Finally, the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered in the claims of the present invention.
