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 text of the description.

[0026] As an embodiment of this case, the processing method of aramid and ultra-high molecular weight polyethylene composite sheet includes the following steps:

[0027] Step 1) Dip the aramid filaments evenly spread into the glue tank containing the first adhesive, spread the dipped aramid filaments on the surface of the release material, and compound the aramid with the release material The filament is drawn by the feeding system into the drying equipment for drying, and then rewinded to obtain a roll of rubber-containing mono-aramid layer;

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

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 method for manufacturing a polymer composite board, in particular to a processing method for a aramid and ultra-high molecular weight polyethylene composite board. Background technique [0002] With the development of national defense, aerospace, ocean-going operations and various civil fields, the performance requirements of protective materials and reinforced composite materials are increasing. Among them, it is difficult to meet multiple requirements at the same time due to the defects of the respective materials for the sheet products composited by a single-material non-weft cloth. Such as: aramid fiber latitude cloth has good flexibility, but poor light resistance, water and chemical properties; high-strength high modulus polyethylene fiber latitude cloth is light in weight, high protection ability, good water resistance, light and chemical stability, but not resistant to high temperature and breakage The extension is large,...
