Abstract
The invention discloses a modified engineering plastic which is composed of the following components in percentage by weight: 60-85% of polyamide resin, 10-25% of glass fiber, 0-1% of lubricant, 1-5% of impact modifier and 5-10% of graft compatilizer. The polyamide resin is nylon 6, the lubricant is TAF, the impact modifier is a methyl methacrylate-butadiene-styrene terpolymer modifier, and the graft compatilizer is a polysiloxane-acrylate compatilizer. The modified engineering plastic has higher strength on the premise of fully displaying the light weight and durability of the nylon 6 material.
Description
Technical field
The invention belongs to technical field of polymer materials, be specifically related to a kind of engineering plastics of modification.
Background technology
Polyamide material, particularly nylon 6 are a kind of raw materials that the fields such as automobile component, mechanical part, electronic product components, engineering accessory are commonly used, and it has the advantages such as thermoplasticity, lightweight, good toughness, chemicals-resistant and good endurance.The excellent properties of polyamide material is mainly derived from intramolecular amide group, and amide group polarity is strong, stability is high, can also form hydrogen bond, substitutes the large and metallic substance that cost is high of weight gradually at present with its engineering plastics be prepared from.
Nylon 6 engineering plastic of the present invention mainly for be stationery field, stationery is a class staple of direct body contact, therefore certain requirement is had to its security, in addition, for slightly large-scale stationery, as file cabinet, computer related supplies etc., also improving constantly high the asking of the intensity of engineering materials, also there is many defects for above 2 in nylon 6 class engineering plastics of the prior art.
Summary of the invention
The object of this invention is to provide a kind of Modified Nylon 6 Engineering Plastics.
The present invention is achieved by the following technical solutions: a kind of modified engineered plastic, is made up of following compositions in weight percentage: polyamide resin 60-85%, glass fibre 10-25%, lubricant 0-1%, impact modifier 1-5%, grafting compatilizer 5-10%;
Further, described each weight percentages of components is: polyamide resin 75%, glass fibre 15%, lubricant 0.4%, impact modifier 2.5%, grafting compatilizer 7.1%;
Further, described polyamide resin is nylon 6;
Further, described lubricant is the modified product (TAF) of two ethylene hard fatty acids acid amides;
Further, described impact modifier is methyl methacrylate, divinyl and cinnamic terpolymer properties-correcting agent;
Further, described grafting compatilizer is polysiloxane-esters of acrylic acid compatilizer.
The beneficial effect that the present invention reaches:
(1) modified engineered plastic of the present invention is giving full play on the lightweight of nylon 6 material itself, weather resistance basis, also improves its intensity;
(2) use of glass fibre not only increases the tensile property of engineering materials of the present invention, as a kind of fire retardant material while glass fibre, also improves the flame retardant properties of engineering materials of the present invention;
(3) methyl methacrylate, divinyl and vinylbenzene (MBS) they are the anti-impact modifiers of a kind of core, shell structure, and its use considerably increases the shock-resistance of engineering plastics of the present invention;
(4) interpolation of lubricant TFA improves the processing fluidity of engineering plastics of the present invention and the surface smoothness of material, and above component has synergy to the excellent properties that this product finally obtains.
