Abstract

The invention discloses an environmental protection plastic, which comprises the following components by weight: 35.5-68.5% of nylon 66, 20-32.5% of halogen-free alkali-free glass fiber, 0.1-3.5% of heat stabilizer, 0.2-1.8% of glycol resistant processing agent, 0.1-3.2% of flexibilizer, 0.1-0.8% of nucleating agent, 5-12% of compatibilizer, 2-8% of coupling agent, 0.5-3.5% of mica and 0.5-3.5% of active carbon. The environmental protection plastic has the beneficial effects that the appearance is smoother, the environmental protection plastic can resist glycol, the strength is good, the production cost is reduced, and the environment can be protected.

Description

Environmentally-friendly plastic

Technical field

The invention discloses a kind of organic polymer composite, more particularly, relate to a kind of environmentally-friendly plastic.

Background technology

Nylon 66 is polyamide resins, one of several engineering plastics that application is at present maximum, his amide group has polarity, in his structure, there is well-set hydrogen bond, make the fusing point of nylon 66 higher, have good physical and mechanical property and wear resistance and self lubricity, these Comprehensive Characteristics are that other plastics are not available.But the heat-drawn wire of pure nylon 66 is lower, and water-absorbent is large, before water suction, shock strength is on the low side, the rigidity shortcoming such as decline to a great extent again after water suction, thus limit the application of nylon 66, and then dwindled again downstream industry design engineer's selection leeway.Therefore, launched nylon 66 to carry out composite modified research.And improve the most universal method that the comprehensive physical mechanics property the subject of knowledge and the object of knowledge of nylon 66 material uses, adopt exactly glass fiber reinforced nylon 66.But glass fiber reinforced nylon 66 is in significantly improving nylon 66 physical and mechanical properties, there is again individual distinct disadvantage, exactly because glass and nylon 66 two-phase interfaces are difficult for good combination, cause easily producing glass emergence on the surface phenomenon at product surface, namely the said dew of insider is fine/floating fine conventionally, so just obviously reduce product surface smooth finish, make product surface coarse and grow dim, thereby limited the application on the product that this starting material have relatively high expectations at effects on surface smooth finish or aesthetic measure.In addition, although the resistance to person's voltinism of nylon 66 self is fine, but water-intake rate is higher owing to self existing, can absorb for a long time airborne moisture, thereby cause physical property to change, especially in the environment of long-term continuous high temperature high humidity, this shortcoming has become and cannot accept, and must significantly be improved.

In the market, only have external large multinational company of several families improve do aspect these shortcomings better, and the product of domestic enterprise always can not accomplish there is better effects simultaneously in outward appearance, heat-proof aging, ethylene glycol resistant, high strength aspect these.

Summary of the invention

The present invention is directed to the deficiencies in the prior art, the invention provides a kind of product and have the ageing-resistant environmentally-friendly plastic of better effects.

The present invention solves the problems of the technologies described above adopted technical scheme as described below:

A kind of environmentally-friendly plastic of the present invention, is made up of by weight following composition, nylon 66:35.5-68.5%, Halogen alkali-free glass fiber: 20-32.5%; Thermo-stabilizer: O.1-3.5%; Ethylene glycol resistant treatment agent: 0.2-1.8%; Toughner: 0.1-3.2%; Nucleator: 0.1-0.8%; Expanding material: 5-12%, coupling agent 2-8%; Mica: 0.5-3.5%; Gac: 0.5-3.5%.

The Production Flow Chart of environmentally-friendly plastic of the present invention is: monomer nylon 66 is dried in high temperature, remove impurity, again nylon 66 is dissolved in and is mixed with Halogen alkali-free glass fiber, thermo-stabilizer, ethylene glycol resistant treatment agent, tough dose of Scarabaeiform, nucleator, mica, antioxidant, antiaging agent, the polyreaction of carrying out in the solvent of gac, the temperature of reaction is controlled to 90 ℃, several reagent add chemical property and the physicals that can improve plastics, make it have ageing-resistant performance, after question response finishes, the polymkeric substance obtaining is latex, polymkeric substance is placed in mould, heating is also rotation simultaneously, reaction is about 20 minutes, carry out again cooling, then with working cycle melting gradually, form the homogeneous phase layer of uniform thickness, mould proceeds to cooling work area subsequently, by forced ventilation or spray water cooling, then be placed on workspace, can make ageing-resistant environmentally-friendly plastic.

The advantage of environmentally-friendly plastic of the present invention: by adding of several reagent, the domestic supplementary material of the little employing of environmental pollution and additive, also meet all environmental requirements simultaneously, greatly improved the competitive power of product on market.

Embodiment

Be below the most preferred embodiment of environmentally-friendly plastic raw material of the present invention, therefore do not limit protection scope of the present invention.

Embodiment mono-, provides environmentally-friendly plastic, is made up of by weight nylon 66:61.2%, Halogen alkali-free glass fiber: 22.5% following composition; Thermo-stabilizer: 2.8%; Ethylene glycol resistant treatment agent: 0.9%; Toughner: 1.9%; Nucleator: 0.6%; Expanding material: 5-12%, coupling agent 2-8%; Mica: 0.5-3.5%; Gac: 0.5-3.5%.Monomer nylon 66 is dried in high temperature, remove impurity, again nylon 66 is dissolved in and is mixed with Halogen alkali-free glass fiber, thermo-stabilizer, ethylene glycol resistant treatment agent, toughner, nucleator, mica, antioxidant, antiaging agent, the polyreaction of carrying out in the solvent of gac, the temperature of reaction is controlled to 90 ℃, after reaction finishes, the polymkeric substance obtaining is latex, polymkeric substance is placed in mould, heating is also rotation simultaneously, reaction is about 20 minutes, carry out again cooling, then with working cycle melting gradually, form the homogeneous phase layer of uniform thickness, mould proceeds to cooling work area subsequently, by forced ventilation or spray water cooling, then be placed on workspace, can make environmentally-friendly plastic.

The above; instrument is the specific embodiment of the present invention; but protection scope of the present invention is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the present invention; the variation that can expect without creative work or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
