Problems solved by technology

The two important factors of strength and quality are required to be taken into account by the small balls. Many small balls on the market often sacrifice strength to reduce quality or sacrifice quality to increase strength. The quality of the ball, but because the resin or resin / fiber composite material used as the sealing and structural support layer has a certain strength at room temperature, but when the ambient temperature reaches 120 ° C ~ 200 ° C, due to the structural characteristics of the fiber and the resin The high temperature fluidity will lead to a significant drop in the pressure resistance and sealing performance of the ball

Embodiment 1

[0034] Take by weighing 20 parts of absolute ethanol, 4 parts of flake graphite, stir in vacuum defoamer for 20 minutes under normal temperature, form flake graphite dispersion liquid,

[0035] Add the above dispersion liquid to 100 parts of bisphenol A epoxy resin, heat the resin to 80°C, stir continuously for 3 hours, let the absolute alcohol evaporate completely, then add 30 parts of amine curing agent (modified aliphatic amine curing agent ) after stirring for 30 minutes to be prepared into flake graphite reinforced resin;

[0036] The diameter of the polyurethane ball is 3mm to 40mm. The polyurethane ball is processed by rigid polyurethane foam, and a flame retardant is added in the polyurethane. The flame retardant is tris(2-chloroethyl)phosphate, tris(2-chloropropyl)phosphate halogenated phosphoric acid ester compound and phosphoric acid ester flame retardant, and the closed cell rate of polyurethane ball foam is 70%~ 90%, the density is 0.03g / cm 3 ~0.045g / cm 3 .

Abstract

The invention discloses flake graphite reinforced resin composite spheres and a preparation method and aims at providing the flake graphite reinforced resin composite spheres with high compressive strength, low weight, high temperature resistance and good air tightness according to the structural characteristics of flake graphite. The flake graphite reinforced resin composite spheres have good air tightness and heat preservation and can be applied in the fields of chemical catalysis, thermal insulation materials, ocean engineering and the like.

Description

technical field [0001] The invention relates to a novel light-weight and high-strength pellet produced by using carbon nanofiller, in particular to a flake graphite-reinforced resin composite ball and a preparation method thereof. Background technique [0002] Lightweight and high-strength pellets are widely used in thermal insulation, structural support, high temperature resistant materials, chemical catalysis, marine engineering and other fields. The two important factors of strength and quality are required to be taken into account by the small balls. Many small balls on the market often sacrifice strength to reduce quality or sacrifice quality to increase strength. The quality of the ball, but because the resin or resin / fiber composite material used as the sealing and structural support layer has a certain strength at room temperature, but when the ambient temperature reaches 120 ° C ~ 200 ° C, due to the structural characteristics of the fiber and the resin The high te...
