Embodiment 1

[0049] Mix 98g of maleic anhydride, 200g of 2,3-butanediol, and 0.06g of tetra-n-butyl titanate. Add it to a 250mL three-necked flask equipped with a mechanical stirring device. After all the materials are added, equip the flask with a set of condensation device, vacuumize and fill with nitrogen three times, remove the oxygen in the reaction vessel to ensure that the esterification reaction is carried out under nitrogen, and heat until the reaction mixture is completely melted / dissolved into a homogeneous phase After the system, the esterification reaction was stirred at 200° C. for 5 h, and in the process, water was steamed out from the reaction mixture as a by-product until the amount of water reached 92% of the theoretical calculation amount (the theoretical calculation molar weight of water was equal to that of maleic diethylene glycol) molar amount of anhydride).

[0050] 0.05 g of zinc acetate was added to the reaction mixture as a polycondensation catalyst. The polyme...

Embodiment 2

[0055] Add 49g of maleic anhydride, 73g of adipic acid, 150g of 2,3-butanediol, 100g of 1,4-butanediol, and 0.93g of magnesium acetate into a 250mL three-necked flask equipped with a mechanical stirring device. After all the materials are added, equip the flask with a set of condensation device, vacuumize and fill with nitrogen three times, remove the oxygen in the reaction vessel to ensure that the esterification reaction is carried out under nitrogen, and heat until the reaction mixture is completely melted / dissolved into a homogeneous phase After the system, the esterification reaction was stirred at 210° C. for 4 h. In the process, water was steamed out from the reaction mixture as a by-product until the amount of water reached 92% of the theoretical calculation amount (the theoretical calculation molar weight of water was equal to 1 times of cis-butyl the sum of the molar weight of olefinic anhydride and twice the molar weight of adipic acid).

[0056] 0.93 g of antimony ...

Embodiment 3

[0061] 30g maleic anhydride, 59g phthalic anhydride, 52g dimethyl adipate, 150g 2,3-butanediol, 50g ethylene glycol, 0.02g tetraisooctyl titanate, 0.03g Antimony acetate was added to a 250mL three-necked flask equipped with a mechanical stirring device. After all the materials are added, equip the flask with a set of condensing devices, vacuumize and fill with nitrogen three times, remove the oxygen in the reaction vessel to ensure that the transesterification and esterification reactions are carried out under nitrogen, and heat until the reaction mixture is completely melted / dissolved After becoming a homogeneous system, the transesterification and esterification reactions were stirred at 180° C. for 8 h. During this process, water and methanol were distilled out from the reaction mixture as by-products until the amount of the distillate reached 92% of the theoretically calculated amount (water The theoretically calculated molar weight is equal to the sum of the molar weight ...

Abstract

The invention belongs to the preparation field of glass fiber reinforced plastics, and discloses a glass fiber reinforced plastics based on 2,3-butanediol, and a preparation method thereof. The glass fiber reinforced plastics have the following repetitive structure unit defined as in the description, wherein R1 is selected from -CH(CH3)-CH(CH3)- and -(CH2)o-; R2 is selected from -(CH2)p- and ortho-position-substituted benzene; n is from 1 to 100; m is from 1 to 100; o is from 2 to 13; and p is from 0 to 11. The invention also discloses the preparation method of the glass fiber reinforced plastics based on 2,3-butanediol. Products obtained by the method have light weight, high strength, good corrosion-resistant performance, thermal performance and electrical performance, and have wide applications in aviation, rocket, spacecraft, high voltage, insulation, heat-insulation and corrosion-resistant containers, and other products required to lighten self-weight.

Description

technical field [0001] The invention belongs to the field of glass fiber reinforced plastic material preparation, and in particular relates to a glass fiber reinforced plastic based on 2,3-butanediol and a preparation method thereof. Background technique [0002] Organisms with life activities on the earth are all composed of organic matter. Organic matter can produce hexose and pentose sugar through biotransformation, among which hexose sugar (mainly glucose) is easy to ferment, and pentose sugar is represented by xylose, which is the main sugar. A potentially important source of product. The main product of the fermentation of xylose and glucose by Klebsiella oxytoca is 2,3-butanediol. In addition, other microorganisms such as Bacillus, Aeromonas hydrophila and several Serratia species can also produce 2,3-Butanediol. Therefore, the preparation and production process of 2,3-butanediol is very different from other chemical products. It completely gets rid of the dependenc...
