But basalt fiber is inorganic mineral fiber, has very smooth surface, is chemically inert, lacks active oxygen-containing groups, has poor surface hydrophilicity, and limits the application field.
At present, basalt fibers and polybutylene succinate are compounded into fully-degradable plates with very good performances in all aspects.

Firstly, ultrasonically cleaning basalt fibers by using an acetone solution, then cleaning and drying by using deionized water, and then separating into single fibers; then carrying out plasma treatment on the basalt single fiber for 60s with the power of 200-300W, and obtaining modified basalt fabric after the treatment;
(3) Laying down
Laying the modified basalt fabric in a hot-pressing die in a warp-weft crossing mode, laying 8 layers, laying a layer of polybutylene succinate film between every two layers, wherein the volume content of the modified basalt fiber is 30-35%;
(4) Hot pressing
Firstly, the temperature is increased to 118 ℃, the pressure is set to 2.5MPa, the resin is preheated after 1 minute of heat preservation, then the temperature is increased to 120 ℃, and the heat preservation is carried out for 10 minutes;
(5) Cooling and demoulding
The basalt fabric polybutylene succinate composite board is formed at one time, does not need to be compounded layer by layer, can be completely degraded, has no harm to the environment, and has the strength as high as 235.5MPa.
2. The method of claim 1, wherein the basalt fibers of step (2) are desized basalt fibers.
3. The method of claim 2, wherein the plasma treatment in step (2) is performed using a radio frequency plasma generator.
4. A method according to claim 3, wherein the plasma treatment in step (2) is performed by: fixing the basalt single fiber on a paper frame, placing the paper frame in a plasma processing chamber, and turning on a radio frequency power supply and an automatic radio frequency matcher to perform plasma processing.
5. The method according to claim 4, wherein a stainless steel spacer plate having a certain thickness is placed between two pressing plates of a hot pressing mold at the time of hot pressing in the step (4) to ensure that a composite plate having a uniform thickness is obtained, and polyimide is used as a release paper.
6. A basalt fabric polybutylene succinate composite board prepared by the preparation method of any one of claims 1 to 5.
