Abstract
The invention discloses a special phenolic glass steel mould plastic, and belongs to the technical field of high-molecular materials. The special phenolic glass steel mould plastic comprises the following materials in parts by weight: 38-42 parts of phenolic resin, 3.2-6 parts of melamine resin, 2.8-6 parts of a curing agent, 1.2-2.5 parts of a curing accelerant, 1.6-2.5 parts of a mould releasing agent, 50-60 parts of filler, 0.5-1.2 parts of a reinforcing agent and 21-26 parts of reinforced fiber. The special phenolic glass steel mould plastic has the characteristics of good heat resistance and high strength; and by test, the bending strength is 80MPa, the thermal distortion temperature is 220 DEG C and the flame retardancy reaches UL-94-V-0 grade (3mm).
Description
Technical field
The invention belongs to technical field of polymer materials, be specifically related to the glass fibre reinforced plastics molded material of a kind of special type phenolic.
Background technology
Because the phenolic fiberglass reinforced plastics moulding compound has preferably thermotolerance, intensity height, convenient formation, the multiple advantage such as cheap, so is widely used in all trades and professions.Along with electric and electronic component are used day by day variation, also more and more higher to the requirement such as flexural strength, thermal distortion, flame retardant resistance and insulativity of phenolic fiberglass reinforced plastics material.Therefore how these performances of General Promotion are directions that present industry is pursued.
Summary of the invention
