Embodiment 1

[0053] Add 80kg of PF5220, 5kg of SQEB-801EK75, 5kg of polyvinyl alcohol, 5kg of ammonium polyphosphate, and 5kg of aluminum hydroxide into the reaction kettle, stir at high speed for 120min, and obtain a prepreg glue with a density of 1.1g / m 3 ; Pour the prepreg glue into the dipping tank of the gluing machine, pre-soak and main dip through the gluing machine, evenly coat the resin glue on the continuous fabric, the continuous fabric is 300g glass fiber satin cloth, impregnate The glass fiber cloth is baked in an oven at 110-140°C, and the production speed is 2m / min. During this process, the resin content is controlled to be 45±3%. After the production is completed, it is rolled up and covered with a layer of PE grid film on both sides; into composites. Peel off the PE grid film of the produced composite parts, cut them into 30×30cm size, stack 8 pieces together, and press them with a hot press. The pressing temperature is 140°C, the time is 1h, and the pressure is from 0.5Mp...

Embodiment 2

[0055] Add 70kg of PF5220, 10kg of SQEB-801EK75, 5kg of polyvinyl alcohol, 10kg of ammonium polyphosphate, 5kg of aluminum hydroxide, and an appropriate amount of methanol into the reactor, and stir at high speed for 120 minutes to obtain a prepreg glue with a density of 1.1g / m 3 ; Pour the prepreg glue into the dipping tank of the gluing machine, pre-soak and main dip through the gluing machine, evenly coat the resin glue on the continuous fabric, the continuous fabric is 300g glass fiber satin cloth, impregnate The glass fiber cloth is baked in an oven at 110-140°C, and the production speed is 2m / min. During this process, the resin content is controlled to be 45±3%. After the production is completed, it is rolled up and covered with a layer of PE grid film on both sides; into composites. Other strength tests are the same as in Example 1.

Embodiment 3

[0057] Add 60kg of PF5220, 15kg of SQEB-801EK75, 5kg of polyvinyl alcohol, 10kg of ammonium polyphosphate, 10kg of aluminum hydroxide, and an appropriate amount of methanol into the reaction kettle, stir at high speed for 120min, and obtain a prepreg glue with a density of 1.1g / m 3 ; Pour the prepreg glue into the dipping tank of the gluing machine, pre-soak and main dip through the gluing machine, evenly coat the resin glue on the continuous fabric, the continuous fabric is 300g glass fiber satin cloth, impregnate The glass fiber cloth is baked in an oven at 110-140°C, and the production speed is 2m / min. During this process, the resin content is controlled to be 45±3%. After the production is completed, it is rolled up and covered with a layer of PE grid film on both sides; into composites. Other strength tests are the same as in Example 1.

Abstract

The invention provides a resin composition, a laminated board, a prepreg and a preparation method and application thereof. A resin composition, which is mainly composed of the following ingredients: by weight, 40-90% of thermosetting phenolic resin, 5-20% of phosphorus-containing epoxy resin, 1-30% of halogen-free flame retardant, and 1-30% of inorganic filler 20%, toughening agent 3~30%; The toughening agent is selected from polyester, polysulfone, polyetherimide, polyphenylene ether, polyethersulfone, polyolefin and its derivatives, polyvinyl alcohol, poly One or more of vinyl butyral, nitrile rubber and its derivatives, preferably one or more of polyolefin and its derivatives, polyvinyl alcohol and its derivatives, nitrile rubber and its derivatives kind. The invention solves the problem of low bonding strength and impact resistance strength of the existing prepreg.

Description

technical field [0001] The invention relates to the field of chemical technology, in particular to a resin composition, a laminate, a prepreg, a preparation method and an application thereof. Background technique [0002] A prepreg is a semi-finished product of fiber reinforced plastic that is pre-impregnated with resin and can be stored for immediate use in the manufacture of composite products when required. Commonly used fibers are carbon fibers, glass fibers and other reinforcing fibers. Prepregs are divided into thermosetting and thermoplastic prepregs, of which thermosetting prepregs are mainly epoxy resin prepregs, phenolic resin prepregs, bismaleimide resin prepregs, cyanate ester prepregs Among them, epoxy resin prepreg is the most widely used. However, with the expansion of the application direction of composite materials, the interior materials in rail transit, ships, automobiles, aircrafts and other fields have higher and higher requirements for flame retardanc...
