Abstract
The invention discloses an anti-aging polypropylene switch comprising the following components in parts by mass: 100 parts of PP (Polypropylene), 0.5-2.5 parts of carbon black, 1-2 parts of an antioxidant 1010, 0.1-1 part of an antioxidant CA, 0.1-0.5 part of BHT (Butylated Hydroxytoluene), 0.5-1 part of titanium dioxide, 0.5-0.8 part of DLTP (Dydecyl Thiopropionate), 20-30 parts of calcium carbonate, 2-4 parts of an ultraviolet absorber, 8-10 parts of EBS (Ethylene Bis Stearamide), 0.5-2 parts of nanometer zirconium phosphate silver loaded antibacterial agent, 3-10 parts of LDPE (Low-Density Polyethylene) and 5-15 parts of CPE (Chlorinated Polyethylene). The anti-aging polypropylene switch has the tensile strength of 34-35MPa, the bending strength of 40-50MPa, the hardness of 98-100, the heat deflection temperature of 145-160 DEG C and the 500h light aging impact strength retention rate of 100% and is capable of inhibiting bacteria, resisting wear and ultraviolet radiation, thus being widely produced and constantly replacing the traditional material.
Description
Technical field
The application belongs to plastic material field, relates in particular to the anti-aging switch of a kind of polypropylene.
Background technology
Polypropylene is the polymkeric substance of nontoxic, odorless, the tasteless high crystallization of oyster white, is one of kind the lightest in current all plastics.It is stable especially to water, and the water-intake rate in water is only 0.01%, molecular weight approximately 80,000 one 15 ten thousand.Good moldability, but because of shrinking percentage large (for 1%-2.5%). thick article easily caves in, and to the higher part of some dimensional precisioies, is also difficult to reach requirement, and product surface good luster is easy to painted.Nontoxic, tasteless, density is little, and intensity, rigidity, hardness thermotolerance are all better than low pressure polyethylene, can be about 100 ℃ uses.There is good electrical property and high-frequency insulation and be not subject to humidity effect, but becoming fragile during low temperature, not wear-resisting, easily aging.Be suitable for making common mechanical part, corrosion-resistant part and insulating part.The organic solvents such as common acid, alkali work hardly to it, can be used for tableware.
The polyacrylic industrial production of China starts from 20 century 70s, development through more than 30 years, substantially formed the multiple production technique such as solvent method, liquid phase body-vapor phase process, batch liquid bulk polymerization, vapor phase process and developed simultaneously, the production pattern that large, medium and small industrial scale coexists.The large-scale polypropylene production apparatus of China be take imported technology as main now, and medium-sized and small-sized polypropylene production apparatus be take domestic technology as main; China's polypropylene output in the future several years has larger growth, but produce still, for not enough, needs, and China has become the maximum polypropylene net importer in the whole world.But because output in domestic increases very soon, import interdependency is on a declining curve generally.China's polypropylene is in the coming years, apparent consumption amount still can keep higher speedup, import volume will increase, polypropylene industry has a extensive future China, development along with social city, technicalization, hommization, design a kind of tensile strength, flexural strength is high, aging-resistant polypropylene switch fabric, to meet the need of market, is very important.
Summary of the invention
the technical problem solving:
The technical problems such as the application is low for existing polypropylene switch tensile strength and flexural strength, not ageing-resistant, provide a kind of polypropylene anti-aging switch.
