Abstract
The invention relates to a continuous glass fiber unidirectional thermoplastic composite plate and a preparation method thereof. The preparation process concretely comprises the following steps: untwisted glass fiber yarns firstly pass through an EVA emulsion adhesive groove at the set velocity under the action of traction force and then are dried by passing through an infrared drying region so as to form an EVA copolymer resin layer on the surface of glass fibers; and the treated glass fiber yarns and polypropylene fibers are alternatively and tightly arranged, the polypropylene fibers are fused and dip the glass fibers under grinding of a rolling machine at the temperature of 200 DEG C to form a unidirectional composite plate, and the unidirectional composite plate is cooled and shorn to obtain GF/PP unidirectional composite plates in different sizes and specifications. According to the preparation method disclosed by the invention, by introducing the EVA copolymer resin layer on the surface of glass fiber yarns, the problem that interfaces of polypropylene and glass fibers and a thermoplastic melt in a glass fiber yarn bundle are difficultly dipped is solved, and the prepared thermoplastic plate is low in porosity and high in strengthen, rigidity and impact toughness.
Description
Technical field
The present invention relates to a kind of unidirectional heat plastic composites sheet material and manufacturing technology thereof.
Background technology
Thermoplastic resin based composite material has that density is little, flexible design, be easily designed to one-piece construction, corrosion-resistant, heat-resisting/every electric, shock-resistant, antivibration, the advantage such as recyclable, the application in automobile component has great importance for automotive energy-saving emission-reducing.Can the fiber in thermoplastic composite give full play to its enhancement, depends on the interface cohesion situation between fiber and matrix.But, be generally solid-state under plastics normal temperature and not polar functionalities in molecular chain, be difficult to form effective interfacial adhesion with glass fibre.On the one hand, in the preparation process of thermoplastic composite more than heating temperatures to plastics fusing point, how to make the very high plastic melt of viscosity and glass fibre a be formed key that good dipping is recombining process; On the other hand, plastics and glass fibre affinity bad, the bonding being improved glass and plastics by the surface modification to fiber and the modification to matrix is another key point to improve the ability of compound interface transmitted load.The present invention is by carrying out emulsion process at fiberglass surfacing, flexibility function layer is introduced between fiber and plastics, flexibility function layer is utilized to have and the functional group of good combination between fiber and plastics, under the prerequisite not changing composite material processing equipment and processing conditions, improve plastics to be connected with the interface of glass fibre, prepare unidirectional heat plastic composites sheet material, improve the toughness of thermoplastic composite, intensity, rigidity, improve its processibility simultaneously.
Summary of the invention
A kind of unidirectional heat plastic composites sheet material of the present invention and manufacturing technology thereof, concrete preparation technology is as follows:
Non-twisting glass fibre yarn under the effect of tractive force by the speed set first by EVA emulsion glue groove; Then, carry out drying through infrared drying district, namely form EVA copolymer resins layer at fiberglass surfacing.The glass fiber yarn handled well and polypropylene fibre replace close-packed arrays, under the roller presses of 200 DEG C roll, polypropylene fibre melting impregnated glass fiber form unidirectional composite material sheet material, and namely cooling, cutting obtain the GF/PP unidirectional composite material sheet material of different size specification.
Beneficial effect
By adopting the Non-twisting glass fibre yarn of different size and the proportioning of polypropylene fibre, the unidirectional composite material sheet thickness 0.15 ~ 0.45mm of preparation, fiber quality percentage composition 20% ~ 50%.
