Embodiment 1

[0047] The high-pressure-resistant polyester BMC composite material in this embodiment includes 80 parts of BMC and 20 parts of epoxy resin material in parts by weight.

[0048] Wherein, in parts by weight, the bulk molding compound comprises the following components:

[0049]

[0050] Among them, the model of o-phthalic unsaturated polyester resin is P17-902 produced by Jinling Liliansi Resin Co., Ltd., and the model of polystyrene is 666D produced by Yanshan Petrochemical Company.

[0051] The preparation method of bulk molding compound is as follows: according to the above ratio, unsaturated polyester resin, low shrinkage agent, initiator, release agent and color paste are mixed and dispersed, and stirred for 40 minutes to form a paste-like material; Mix and disperse aluminum and calcium carbonate powder fillers, mix and stir with sauce paste material for 8 minutes to prepare a paste material, and finally add glass fiber in the formulated amount to the obtained paste mat...

Embodiment 2

[0056] The difference between this embodiment and embodiment 1 is that the epoxy resin material is compounded by epoxy resin E44 and curing agent low-molecular polyamide 650 with a mass ratio of 8:1, and the others are the same as those of embodiment 1. same.

Embodiment 3

[0058] The difference between this embodiment and embodiment 1 is that the epoxy resin material is compounded by epoxy resin E44 and curing agent low-molecular polyamide 650 with a mass ratio of 6:1, and the others are the same as those of embodiment 1. same.

Abstract

The invention discloses a polyester bulk molding compound composite material with high pressure resistance and a preparation method thereof. The polyester bulk molding compound composite material withhigh pressure resistance comprises the following components in parts by weight: 70 to 99 parts of bulk molding compound and 1 to 30 parts of epoxy resin material. Compared with a traditional BMC material, the high-pressure-resistance polyester bulk molding compound composite material has the electrical property improved by 15 to 20%, and has good pressure resistance and mechanical property.

Description

technical field [0001] The invention relates to the technical field of new materials, and relates to a polyester bulk molding compound composite material and a preparation method thereof, in particular to a high-pressure-resistant polyester bulk molding compound composite material and a preparation method thereof. Background technique [0002] In the 1930s, the polymer theory further promoted the development of polymer materials, and achievements such as polyethylene, nylon fiber, unsaturated resin and epoxy resin appeared one after another. Later, glass fiber / unsaturated resin (glass fiber reinforced material) also came out in the United States. In the 1960s, the German Bayer company launched the production of polyester molding compounds, and then gradually extended to Europe, the Americas, and the Asia-Pacific region, and formed mechanized and mass production, which greatly promoted the progress of industrial material technology. At the same time, under the impetus of ind...
