Abstract
The invention discloses glass fiber reinforced polypropylene plastic and a preparation method thereof. The glass fiber reinforced polypropylene plastic comprises the following components in parts by weight: 40-60 parts of PP resin, 25-35 parts of glass fiber, 15-25 parts of a PP-g-MAH compatilizer and 0.1-0.5 parts of an antioxidant. Relative to pure PP plastic, the glass fiber reinforced polypropylene plastic has high rigid intensity, and can be widely applied to production of products such as household appliances, plastic pipes and automotive interior parts.
Description
Technical field
The present invention relates to a kind of plastics and preparation method thereof, relate in particular to a kind of glass-reinforced polypropylene plastics and preparation method thereof.
Background technology
Polypropylene (Polypropylene is called for short PP) is a kind of hemicrystalline thermoplastics.Have higher shock-resistance, mechanical properties is tough, anti-multiple organic solvent and acid and alkali corrosion.Being widely used in industry member, is one of usually common macromolecular material.
The rigidity of plastics refers to the ability of plastics resistance to deformation.Tensile strength, flexural strength or the tensile modulus, the modulus in flexure that refer generally to.
In prior art, there is the shortcoming of undercapacity in acrylic plastering.
Summary of the invention
For above shortcomings in prior art, one of technical problem to be solved by this invention is to provide a kind of glass-reinforced polypropylene plastics, has higher intensity.
Two of technical problem to be solved by this invention is to provide the preparation method of above-mentioned glass-reinforced polypropylene plastics.
The present invention is achieved through the following technical solutions:
A kind of glass-reinforced polypropylene plastics, the component that comprises following weight parts: 40-60 part PP resin, 25-35 part glass fibre, 15-25 part PP-g-MAH compatilizer, 0.1-0.5 part oxidation inhibitor.
Preferably, the invention provides:
A kind of glass-reinforced polypropylene plastics, the component that comprises following weight parts: 40-60 part PP resin, 25-35 part glass fibre, 15-25 part PP-g-MAH compatilizer, 0.1-0.5 part oxidation inhibitor, 0.2-0.6 part antiseptic-germicide.
Described oxidation inhibitor is antioxidant 1010 or irgasfos 168.
Described antiseptic-germicide is 2-hydroxyl-4-sec.-propyl-2, two (n-to the chlorobenzene biguanides) hexanes of 4,6-cycloheptatriene-1-ketone and/or 1,6-.
Optimally, described antiseptic-germicide is 2-hydroxyl-4-sec.-propyl-2,4,6-cycloheptatriene-1-ketone and 1, the mixture of two (n-to the chlorobenzene biguanides) hexanes of 6-, 2-hydroxyl-4-sec.-propyl-2,4, the weight ratio of two (n-to the chlorobenzene biguanides) hexanes of 6-cycloheptatriene-1-ketone and 1,6-is 3:1-1:3.
Obviously, for improving other performances of product, can also in blend material, add adaptively other auxiliary agents in the present invention, as fire retardant, static inhibitor and pigment etc., its consumption is the conventional amount used of the industry, or adjusts according to the requirement of practical situation.
The present invention also provides the preparation method of above-mentioned glass-reinforced polypropylene plastics: take each component by proportioning, mediate, mixing, extrude, granulation.
The present invention, with respect to pure PP plastics, has higher rigidity intensity.The present invention can be widely used in the production of the products such as household electrical appliance, plastic pipe, automotive upholstery.
