Embodiment 1
[0025] Add 4g of zinc stearate to 400g of phenolic resin, stir evenly, then add 600g of aluminum hydroxide and 4g of active magnesium oxide into the phenolic resin and stir evenly to make phenolic resin glue. Make 2992g non-alkali glass fiber continuously pass through the impregnation tank containing phenolic resin by traction, control the content of sizing and wettability of the non-alkali glass fiber by squeezing rollers, and then cover the upper and lower sides with polyethylene film and roll it up Take it into a roll, and put it in an oven at 50±5°C for 24 hours to make a unidirectional reinforced molding compound of phenolic resin composite material. According to the size of different areas of the mold structure, the phenolic resin composite material unidirectional reinforced molding material is cut into corresponding sizes, and according to the structure of different areas of the mold, the phenolic resin composite material unidirectional reinforced molded material of the ...
Embodiment 2
[0027] Add 120g of zinc stearate into 1600g of phenolic resin, stir evenly, then add 600g of aluminum hydroxide and 40g of active magnesium oxide into the phenolic resin and stir evenly to make phenolic resin glue. 1640g non-alkali glass fiber is continuously passed through the impregnation tank containing phenolic resin by traction, the content of fiber sizing and the wettability of the sizing material are controlled by squeezing rollers, and then the upper and lower sides are covered with polyethylene film and rolled into rolls , placed in a 50±℃ oven for 24 hours to prepare phenolic resin composite unidirectional reinforced molding material. According to the size of different areas of the mold structure, the phenolic resin composite material unidirectional reinforced molding material is cut into corresponding sizes, and according to the structure of different areas of the mold, the phenolic resin composite material unidirectional reinforced molded material of the correspondi...
Embodiment 3
[0029] Add 80g of zinc stearate into 1000g of phenolic resin, stir evenly, then add 800g of aluminum hydroxide and 40g of active magnesium oxide into the phenolic resin in turn, stir evenly, and make phenolic resin glue. Through traction, 2080g of alkali-free glass fiber is continuously passed through the impregnation tank containing phenolic resin, and passed through a pressing roller to control the content of fiber sizing and the wettability of the sizing material. Then, the upper and lower sides are covered with polyethylene film and rolled into a roll. After aging in an oven at 50°C for 24 hours, the unidirectional reinforced molding compound of phenolic resin composite material was obtained. According to the size of different areas of the mold structure, the phenolic resin composite material unidirectional reinforced molding material is cut into corresponding sizes, and according to the structure of different areas of the mold, the phenolic resin composite material unidire...
