Problems solved by technology

However, the high temperature and long curing time required for phenolic resin curing make its production efficiency low, and phenolic resin is brittle, poor in toughness, and poor in mechanical properties, which seriously restricts the wider application of phenolic resin
Therefore, phenolic resins with poor comprehensive properties cannot be directly applied to stamping die materials for prototype car trial production

Embodiment example

[0040] Example: A phenolic resin composition, the composition includes, according to mass g, 10~40g of phenolic resin, 10~40g of styrene-butadiene rubber, 5~12g of iron powder, 6~8g of carbon-based material, and 7g of non-ferrous metal powder. ~13g, metal oxide 0.2~3g, basalt fiber 10~13g and dispersant 2.4~5.3g. The carbon-based material is selected from carbon nanotubes and / or carbon fibers; the non-ferrous metal powder is selected from at least one of Zr, Ni or Cu; the metal oxide is Al 2 O 3 , TiO 2 , Ni 2 O 3 , Fe 3 O 2 or at least one of CoO. The modified phenolic resin is a polyimide-modified phenolic resin, and the mass ratio of the phenolic resin to the polyimide in the polyimide-modified phenolic resin is 1:0.125~2. The iron powder is selected from reduced iron powder and / or electrolytic iron powder, and the mesh number of the iron powder is selected from 800-1600 mesh. The iron powder includes 2-4 parts of 1600-mesh electrolytic iron powder, 1-3 parts of 160...

Abstract

The invention belongs to the field of polymer composite materials, and particularly relates to a phenolic resin composition, a preparation method thereof, and an application in the preparation of a stamping die. The composition comprises, in parts by mass, 10-40 parts of modified phenolic resin, 10-40 parts of styrene-butadiene rubber, 5-12 parts of iron powder, 6-8 parts of carbon-based material, 7-13 parts of non-ferrous metal powder, 0.2~3 parts of metal oxide, 10~13 parts of modified basalt fiber and 2.4~5.3 parts of dispersant. The phenolic resin composition and its preparation method and application provided by the invention innovatively strengthen the polyimide-modified phenolic resin with various reinforcement phases, comprehensively utilize the reinforcement characteristics and synergistic reinforcement effects of various reinforcement phases, and improve the polymer Comprehensive properties of composite materials.

Description

technical field [0001] The invention belongs to the field of polymer composite materials, and particularly relates to a phenolic resin composition, a preparation method thereof, and an application in the preparation of a stamping die. Background technique [0002] With the vigorous development of the global auto industry, many auto companies need to innovate continuously. The shorter the cycle for vehicle manufacturers to launch new models, the faster the market brand occupation. Whether it is launching a new model or transforming and upgrading the original model, it is necessary to carry out trial production of automobile products to directly reflect whether the appearance and shape of the vehicle, the rationality of size and the quality are qualified. After the design engineer completes the design of the appearance and auto parts, it is necessary to make a prototype car according to the design data, and then make design changes by excavating the shortcomings of the prototy...
