At present, with the continuous promotion of urban construction, the demand and the yield of the glass fiber reinforced plastics are increasingly larger. At the same time, however, a large amount of glass fiber reinforced plastic waste is inevitably produced. If the glass fiber reinforced plastic waste materials are directly buried, not only the waste of resources is caused, but also the environmental pollution is easily caused, because the glass fiber reinforced plastic waste materials are difficult to be completely degraded in the natural environment.

Comparative example 3
The difference from example 2 is that:
the waste material of the polyester glass fiber reinforced plastic is replaced by an equivalent amount of unsaturated polyester.
Performance test data tensile strength: the test is carried out by referring to GB/T1447-2005 fiber reinforced plastics tensile property test method.
Table 1 Performance test data for glass fiber reinforced plastics in examples 1-9 and comparative examples 1-3
Note that: the aging method is that the sun exposure is carried out for 90 days under the same environment.
As can be seen in combination with the present application example 2 and comparative examples 1-2, in combination with table 1: when the glass fiber reinforced plastic is prepared by using the waste polyester glass fiber reinforced plastic, if the ethylene-butene copolymer is replaced by an equivalent amount of the silane coupling agent or the silane coupling agent is replaced by an equivalent amount of the ethylene-butene copolymer, the tensile strength of the glass fiber reinforced plastic is reduced. Wherein, when the ethylene-butene copolymer is replaced by the equivalent silane coupling agent KH550, the tensile strength of the glass fiber reinforced plastic is reduced to the greatest extent. Accordingly, the inventor conjectures that the silane coupling agent and the ethylene-butene copolymer in the application have the effect of synergistically improving the tensile strength of the glass fiber reinforced plastic, because the polyester glass fiber reinforced plastic waste can be uniformly dispersed in unsaturated polyester when the silane coupling agent and the ethylene-butene copolymer are combined, so that a relatively uniform matrix resin is obtained, and in addition, the glass fiber can be uniformly dispersed in the matrix resin, thereby being beneficial to obtaining the glass fiber reinforced plastic with relatively high strength.
As can be seen in combination with the present application, examples 2 and 4-7, and table 1: the modified glass fiber in the embodiment 4 is directly prepared by modifying glass fiber by organic silicon resin, and the tensile strength of the corresponding glass fiber reinforced plastic is increased; the modified glass fiber in the embodiment 5 is prepared by firstly carrying out ultrasonic soaking on the glass fiber by adopting hydrofluoric acid solution to obtain pretreated glass fiber A and then carrying out modification treatment on the pretreated glass fiber A by adopting organic silicon resin, and the tensile strength of the corresponding glass fiber reinforced plastic is also increased, but the increase amplitude is lower than that of the glass fiber reinforced plastic in the embodiment 4; the modified glass fiber in the embodiment 6 is prepared by firstly carrying out ultrasonic soaking on glass fiber by using water to obtain pretreated glass fiber A, then pressing nano silicon dioxide on the pretreated glass fiber A to obtain pretreated glass fiber B, and finally carrying out modification treatment on the pretreated glass fiber B by using organic silicon resin, wherein the corresponding tensile strength of the glass fiber reinforced plastic is also increased, and the increase amplitude is slightly larger than that of the glass fiber reinforced plastic in the embodiment 4; the modified glass fiber in the embodiment 7 is prepared by firstly carrying out ultrasonic soaking on glass fiber by adopting hydrofluoric acid solution to obtain pretreated glass fiber A, then pressing nano silicon dioxide on the pretreated glass fiber A to obtain pretreated glass fiber B, and finally carrying out modification treatment on the pretreated glass fiber B by adopting organic silicon resin, wherein the corresponding glass fiber reinforced plastic has increased tensile strength and increased growth amplitude which is far greater than that of the glass fiber reinforced plastic in the embodiments 4-6. The inventor guesses that the reason is probably that after the glass fiber is soaked in hydrofluoric acid solution in an ultrasonic mode, nano silicon dioxide is more conveniently attached to the glass fiber, so that organic silicon resin can be more stably attached to the outer side of the glass fiber, abrasion resistance of the glass fiber is improved, and the problem that reinforcing effect on plastics is weakened due to structural damage of the glass fiber in a processing process is solved.
As can be seen in combination with example 7, example 9 of the present application and table 1: the tensile strength of the glass fiber reinforced plastic prepared in example 9 is better than that of the glass fiber reinforced plastic prepared in example 7; among them, example 7 is different from example 9 in that in the Sc step of preparing the modified glass fiber of example 9, the temperature of the silicone resin was controlled to 45 ℃. Accordingly, the inventors hypothesize that controlling the temperature of the silicone resin to 45 ℃ is more beneficial for the silicone resin to permeate into the glass fiber, thereby forming a more stable coating film and being capable of better protecting the glass fiber.
As can be seen from a combination of example 9, example 10 and comparative example 3 of the present application and table 1: when the weather-resistant auxiliary agent adopts the combination of the ultraviolet absorber and the hindered light stabilizer, the weather-resistant auxiliary agent is more beneficial to improving the ageing resistance of the glass fiber reinforced plastic. In addition, the strength properties of the glass fiber reinforced plastic produced in example 10 were similar to those of the glass fiber reinforced plastic of comparative example 3 without the scrap of polyester glass fiber reinforced plastic.
