Embodiment 1
[0022] An unsaturated polyester resin glass fiber prepreg for low-temperature and low-pressure molding described in Example 1 of the present invention is composed of the following raw materials: glass fiber, unsaturated polyester resin, nano-magnesium hydroxide, crystalline solid polyester, Release agent, coupling agent, isocyanate, unsaturated low-shrinkage resin, curing agent; among them, glass fiber accounts for 40% by mass of raw materials, unsaturated polyester resin accounts for 50% by mass of raw materials, and nano-magnesium hydroxide accounts for The mass percentage of raw material is 1%. The unsaturated low-shrinkage resin is a styrene solution of polyfumarate-diethylene glycol, and its mass is equivalent to 15% of the mass of the unsaturated polyester resin.
[0023] The isocyanate is a mixture of HDI and MDI, and the mass of the mixture is equivalent to 1% of the mass of the unsaturated low-shrinkage resin.
[0024] Described curing agent is tert-butyl peroxybenzo...
Embodiment 2
[0032] This Example 2 is to adjust the mass content of each component of the unsaturated polyester resin glass fiber prepreg for low-temperature and low-pressure molding, as follows: glass fiber accounts for 50% of the mass percentage of raw materials, unsaturated polyester resin accounts for The mass percentage of raw materials is 35%, and the mass percentage of nano-magnesium hydroxide in raw materials is 6%. The unsaturated low-shrinkage resin is a styrene solution of polyfumarate-diethylene glycol, and its mass is equivalent to 15% of the mass of the unsaturated polyester resin.
[0033] The isocyanate is HDI, and its mass is equivalent to 3% of the mass of the unsaturated low-shrinkage resin.
[0034] Described curing agent is cyclohexanone peroxide, and its quality is equivalent to 3% of unsaturated polyester resin quality.
[0035]The glass fiber is composed of the following fiber raw materials based on the mass percentage of the prepreg: 0.5% carbon fiber, 10% hemp fi...
