Description
Technical Field
The utility model relates to a shellproof picture peg preparation technical field especially relates to a compound shellproof picture peg.
Background
When the ultra-high molecular weight polyethylene composite bulletproof flashboard is prepared, a finished product needs to realize excellent bulletproof performance, the requirement on the performance of a bulletproof material is high, the surface of a PE plate in the composite bulletproof flashboard is very smooth, the cohesiveness is poor, the interface bonding force is low, and materials such as bulletproof ceramics, aramid fiber and the like are also arranged in the composite bulletproof flashboard, so that the cohesiveness of various materials is uneven, and the interface bonding force is different, so that an adhesive with good bonding strength is required to be selected.
The implementation temperature of the existing adhesive (adhesive film) is above 100 ℃, and the bonding effect is optimal even when the implementation temperature reaches above 140 ℃. The existing molding process of the ultra-high molecular weight polyethylene composite bulletproof flashboard using the adhesive is autoclave one-step molding, the implementation temperature of the molding method is between 125 and 135 ℃, and at the molding temperature in the stage, the PE laminated board can be softened to influence the bulletproof performance of the PE laminated board, so that the bulletproof performance of the final finished board (composite bulletproof flashboard) is influenced.
In addition, the bulletproof ceramic and the PE laminated board in the PE composite bulletproof inserting board generate gaps or form cavities due to slight curvature difference, and are not completely attached, so the bulletproof performance of the bulletproof inserting board is influenced. Chinese patent publication No. CN 111319338A discloses a method for molding autoclave, which comprises heating PE to 125-135 ℃ to soften PE to complete filling of cavities and voids, but softening at this temperature greatly weakens the bulletproof performance of PE laminate.
