Description
Technical field
The invention belongs to technical field of composite materials, be specifically related to a kind of scratch resistance, wear-resisting, ageing-resistant compound film nonwoven
Cloth material.
Background technology
Along with the development of composite, composite relies on its specific strength, and specific stiffness is high, and the characteristic that density is light obtains extensively
Application, one of trend of current composite development is to replace traditional thermoset epoxy composite wood with thermoplastic composite
Material.One of reason is that thermoplastic composite by simply heating, can melt and cool down molding, can carry out as metal
Welding, the development for this thermoplastic composite produces the biggest change to market from now on.But thermoplastic composite exists
In its preparation, due to the characteristic of the processing technique of its material own, in manufacturing process, it is impossible to add substantial amounts of uvioresistant and absorb
Agent, anti-wear agent etc., if adding, the mobility of thermoplastic resin can be affected, thus reduce the mechanical property of material, being therefore combined
In the use of the outdoor goods of material, application is few；Owing to resin content is few, fibre reinforced materials is many, and resin volume content is few,
The most smooth at product product surface, the phenomenon such as glass emergence on the surface.In the product having color to require, product colour dispersion inequality
Even；Owing in thermoplastic composite, major part belongs to non-polar material, surface polarity key is few, and bonding force is poor, and this product can
Post forming, it is impossible to add thermosetting gel coat, the most how to improve its surface quality, governs answering of thermoplastic composite
With.
Although at present China's non-woven fabrics industry is a lot, forming method is varied, needle punched non-woven fabrics, spun-bonded non-woven fabrics, molten
Blown non-woven fabric, heat seal non-woven fabrics are a lot of, but film non-woven fabrics still belongs to the primary stage, is the most all with non-woven fabrics as basic unit, single
Face or two-sided film resin, be basically used for packaging material, make packaging bag clothes etc., for its surface and weather-proof can not accomplish long-term
Outdoor use, external E.I.Du Pont Company releases the film nonwoven cloth material being suitable for thermoplastic composite veneer, but its price is high,
Minimum quantity of an order is big, and the delivery cycle is long, the domestic phenomenon without agency even occurs.This restricts sending out of domestic thermoplastic composite
Exhibition, and the domestic current former for film non-woven fabrics and technique are still in the development phase, cannot do for state at all
Outer homogenous quantities is the most slightly weaker than the product of its quality.
Two-sided film non-woven fabrics of Chinese patent CN 1046944039 A mono-kind and preparation method thereof disclose a kind of double
Face film non-woven fabrics is divided into protective layer, nonwoven layer and adhesive linkage 3-tier architecture, though this kind of non-woven fabrics can solve in manufacturing process
The problem that certainly product surface quality and surface tinting strength, tinting power are evenly distributed, but ageing resistance and the scratch-resistant of product can not be given
Wearability, and product surface is PP film, ultra-violet resistance extreme difference, therefore cannot meet outdoor life-time service, greatly reduce product
Practicality.And film non-woven fabrics structurally arranges adhesive linkage, virtually add the cost of film non-woven fabrics so that it is unfavorable
In promoting and selling.
Summary of the invention
It is an object of the invention to provide a kind of scratch resistance, wear-resisting, ageing-resistant compound film nonwoven cloth material.
The object of the present invention is achieved like this, including protective layer, weathering layer and dielectric layer, described weathering layer by comprise with
The component of lower weight portion is made:
Polypropylene 100
Color masterbatch 3-10
Antioxidant 0.4-1
Stabilizer 0.1-0.2
UV absorbent 0.3-0.5.
Compared with prior art, the present invention has the following advantages and beneficial effect:
1. the film non-woven fabrics protective layer that prepared by the present invention is by made by PET, and PET film has optical property, surfacing, light
Clean, Heat stability is good, the feature such as shrinkage factor is little, light aging resisting, owing to its case hardness is high, product surface can be protected to be difficult to scrape
Wound, use single silicon fiml can ensure that its damaged or aging after, can remove easily, not affect the aesthetics of product.
2. the film non-woven fabrics weather-proofization layer that prepared by the present invention is made up of PP modification resin, and product is by adding modification tree
Fat, can improve its weatherability, improves the surface quality of its product by adding color masterbatch.
3. the product nonwoven layer that prepared by the present invention is bond medium layer, makes its one side attachment polypropylene tree by film
Fat, another side is polyester non-woven fabric, and when fitting with thermoplastic composite, non-woven polyester cloth cover can be impregnated with by thermoplastic resin,
Acrylic resin face has part fusing simultaneously, is fitted by roll-in, it is not necessary to glued membrane or adhesive linkage, economizes in raw materials and to material
Material is maximally utilized.
