Embodiment Construction

[0025] The present invention will be described in further detail below, so that those skilled in the art can implement it with reference to the description.

[0026] The processing method of the aramid fiber and ultra-high molecular weight polyethylene composite sheet as an embodiment of the present case comprises the following steps:

[0027] Step 1) Dip the evenly laid aramid filaments into the glue tank containing the first adhesive, lay the dipped aramid filaments on the surface of the release material, and compound the aramid with the release material The filament is drawn into the drying equipment by the coil feeding system for drying, and then coiled to obtain a coiled single aramid fiber layer containing glue;

[0028] Step 2) Dip the uniformly laid ultra-high molecular weight polyethylene filaments into the glue tank containing the second adhesive, lay the soaked polyethylene filaments on the surface of the release material, and compound the release material The poly...

Abstract

The invention discloses an aramid fiber-ultrahigh molecular weight polyethylene composite sheet material processing method. The method comprises fiber impregnation, single fiber layer hot pressing and multiple composite layer hot pressing. First glue comprises a styrene-vinyl acetate copolymer, epoxy resin, terpene resin, polyethylene glycol, p-nitrotoluene and strontium fluoride. Second glue comprises a propylene-vinyl acetate copolymer, polystyrene, terpene resin, polyethylene glycol, 2,4-dimethylphenol and potassium metasilicate. Through improvement of the glue and use of a multi-ingredient composite formula, bonding strength and density of the glue to aramid fibers and polyethylene fibers are effectively improved, and composite sheet material toughness and shock resistance are improved. Through freezing and unfreezing of the fibers subjected to impregnation, glue inner stress and surface tension are effectively reduced. Through UV treatment on the fibers subjected to impregnation, glue and fiber bonding strength is improved and a composite sheet material service life is prolonged.

Description

technical field [0001] The invention relates to a manufacturing method of a polymer composite board, in particular to a processing method of an aramid fiber and ultra-high molecular weight polyethylene composite board. Background technique [0002] With the development of national defense, aerospace, ocean operations and various civilian fields, the performance requirements of protective materials and reinforced composite materials are increasing day by day. Among them, the panel products made of a single material without weft cloth, due to the defects of their respective materials, it is difficult to meet multiple needs at the same time. Such as: Aramid fiber non-weft fabric has good softness, but poor light resistance, water and chemical properties; high-strength high-modulus polyethylene fiber non-weft fabric is light in weight, high in protection ability, good in water resistance, light and chemical stability, but not resistant to high temperature, fracture The extensio...
