Embodiment 1
[0017] The present invention proposes a kind of preparation method of continuous glass fiber rubber prepreg, comprises the steps:
[0018] S1. Surface modification of continuous glass fiber cloth: burn commercial glass fiber cloth at 400°C for 25 minutes to remove surface paraffin to obtain surface heat-treated glass fiber cloth a, and then mix 88% EtOH with 8% The H2O was made into an alcoholic aqueous solution. After adding a coupling agent and stirring for 4 minutes under magnetic stirring, the treatment solution b was prepared. Then, the glass fiber cloth a was soaked in the treatment solution b for 10 minutes until it was completely saturated, and then dried at 85°C for 22 hours. , that is, a surface-modified glass fiber cloth is obtained;
[0019] S2. Preparation of natural rubber glue: dissolve natural rubber in two or more mixed solvents with a solid content of 25%, stir at 900r / min for 1.5h under the action of mechanical stirring until a stable and uniform glue is for...

[0025] The present invention proposes a kind of preparation method of continuous glass fiber rubber prepreg, comprises the steps:
[0026] S1. Surface modification of continuous glass fiber cloth: burn commercial glass fiber cloth at 435°C for 28 minutes to remove surface paraffin to obtain surface heat-treated glass fiber cloth a, and then mix 89% EtOH with 9% The H2O was made into an alcoholic aqueous solution. After adding a coupling agent and stirring for 5 minutes under magnetic stirring, the treatment solution b was obtained. Then, the glass fiber cloth a was soaked in the treatment solution b for 12 minutes until it was completely saturated, and then moved to an environment of 88°C for 23 hours to dry. , that is, a surface-modified glass fiber cloth is obtained;
[0027] S2. Preparation of natural rubber glue: dissolve natural rubber in two or more mixed solvents with a solid content of 30%, stir at 950r / min for 1.8h under the action of mechanical stirring until a stabl...

[0033] The present invention proposes a kind of preparation method of continuous glass fiber rubber prepreg, comprises the steps:
[0034] S1. Surface modification of continuous glass fiber cloth: burn commercial glass fiber cloth at 480°C for 32 minutes to remove surface paraffin to obtain surface heat-treated glass fiber cloth a, and then mix 91% EtOH with 10% The H2O was made into an alcoholic aqueous solution. After adding a coupling agent and stirring for 6 minutes under magnetic stirring, the treatment solution b was obtained. Then, the glass fiber cloth a was soaked in the treatment solution b for 14 minutes until it was completely saturated, and then dried at 92°C for 25 hours. , that is, a surface-modified glass fiber cloth is obtained;
[0035] S2. Preparation of natural rubber glue: dissolve natural rubber in two or more mixed solvents with a solid content of 40%, stir at 1100r / min for 2.2h under the action of mechanical stirring until a stable and uniform glue is f...
