Description
Technical Field
The invention belongs to the field of inorganic materials, and particularly relates to a high-dispersion glass fiber and glass fiber reinforced nylon material, and a preparation method and application thereof.
Background
Nylon is engineering plastic widely applied to industries such as electronics, electrics, automobiles, household appliances and the like, and has the advantages of heat resistance, wear resistance, chemical corrosion resistance and the like. In engineering plastics applications, it is often necessary to fill inorganic materials to advantage in terms of mechanical properties, most often glass fibers. However, because nylon has strong crystallinity, the compatibility of glass fibers and nylon is poor, and the problem of poor dispersibility of glass fibers in nylon is often faced during injection molding.
The glass fiber dispersion problem of the nylon glass fiber reinforced composite material is solved, and generally, a certain amount of dispersing auxiliary agent or component is added into the formula of the composite material to change the crystallinity of nylon, thereby improving the dispersibility of glass fibers in the composite material. For example, in CN106867247a, the transparent nylon component is added to destroy the crystal structure of nylon 66, which is helpful for dispersing glass fiber in the resin, reducing the orientation and anisotropy of glass fiber, reducing the surface shrinkage of the material, and improving the flatness.
In addition, the glass fiber can be subjected to surface modification, for example, CN108285641A discloses a modified glass fiber, and after surface corrosion, the modified glass fiber is immersed in a solution of polytetrafluoroethylene, trivalent metal oxides of lanthanum and cerium for modification, so that the wear resistance and the use hand feeling of the nylon modified material are improved. CN109054372a is a synthetic high molecular polymer, which is impregnated on the surface of glass fiber to improve the dispersibility and the binding property of glass fiber and nylon 66. CN110684342a is to perform plasma gas surface functionalization treatment on glass fiber, so that the surface of the glass fiber contains functional groups such as hydroxyl, carboxyl, carbonyl, amino and the like, the reactivity and compatibility of the glass fiber and the end group of the nylon matrix are improved, and the dispersibility of the glass fiber in nylon is promoted.
The CN105802206A is prepared by adding an interfacial bonding agent into a composite material, wherein one end of the interfacial bonding agent is anchored and adsorbed on the surface of glass fiber, and the other end of the interfacial bonding agent is outwards wound with a nylon molecular chain, so that the interfacial bonding property of the glass fiber and nylon is improved, the dispersibility in a nylon matrix is improved, the orientation of the glass fiber in the matrix is improved, and the performance of the composite material is improved.
However, the post-treatment method for surface dispersion of glass fibers increases the complexity of the high dispersion functional glass fibers, and it is difficult to ensure the uniformity of the distribution of the dispersing aid on the surface of the glass fibers. The method for improving the compatibility of the nylon glass fiber reinforced composite material and the glass fiber reinforced composite material by adding other components into the formula of the nylon glass fiber reinforced composite material has certain limitation, on one hand, the components are difficult to screen, and the compatilizer has influence on the performance of the product, so that the relationship between the improvement of the compatibility and the requirement of the product is difficult to balance; in addition, the crystallinity difference of different types of nylon is larger, and the dispersion problem of glass fiber in different types of nylon is also different, so that the formula added with the compatilizer has no universality in different types of nylon products.
Therefore, developing a glass fiber product which has better dispersibility in various nylon products has important research significance and application value.
Disclosure of Invention
The invention aims to overcome the defects or the shortcomings of the prior art and provide a high-dispersion glass fiber. According to the high-dispersion glass fiber, the characteristic element oxide component is added into the basic glass oxide component, so that the obtained glass fiber has high dispersibility in various nylon materials and has good universality; when the reinforced nylon material is used, post-treatment such as dipping is not needed, and a compatilizer component is not needed to be additionally added, so that the reinforced nylon material can be highly dispersed in the nylon material, and a better reinforcing effect is realized.
Another object of the present invention is to provide a method for preparing the above-mentioned high dispersion glass fiber.
Another object of the present invention is to provide a glass fiber reinforced nylon material.

The inventor researches find that the dispersibility of glass fibers in nylon can be effectively improved by adding a specific amount of characteristic element oxide components into a basic glass oxide component, and the glass fiber is suitable for various nylon materials, has better universality, and probably is because:
the main reason for poor dispersibility of glass fibers in nylon is that the strong hydrogen bonding action among nylon polymer chains is easy to cause aggregation among polymers, and inorganic filling materials are difficult to insert among polymer chains, so that good compatibility is difficult to realize. The divalent metal element in the characteristic element oxide can form a complex bond with an amide bond of a nylon material to break the aggregation of hydrogen bonds among nylon polymer chains, improve the compatibility of glass fibers and nylon and promote the dispersion of the glass fibers in the nylon.
The weight ratio of SrO to ZnO has a critical effect on dispersibility. If the weight ratio of the two is too low, the effect of destroying the nylon hydrogen bond is not obvious enough, and the glass fiber dispersibility is poor; if the weight ratio of the glass fiber to the nylon is too high, the glass fiber is easy to agglomerate, and the dispersibility in nylon is also reduced.
When the glass fiber reinforced nylon material is utilized, after-treatment such as dipping is not needed, and a compatilizer component is not needed to be additionally added, so that the obtained glass fiber reinforced nylon material can be highly dispersed, the glass fiber dispersibility is good, the reinforcing effect can be effectively realized, and the tensile strength, the bending modulus and the bending strength are all obviously improved.
