Abstract
The invention discloses a polymer warning band. The polymer warning band is characterized in that the polymer warning band is blending alloy of polyethylene and polypropylene with high molecular weight, the molecular weight of polyethylene and polypropylene ranges from 1,000,000 to 2,500,000, and the content of polyethylene ranges from 30% to 80%, and is preferably 50%-70%. According to the warning band, the mechanical strength of the product is improved, the durability of the product is improved, and meanwhile, the product is unique in appearance, high in stability and capable of reducing material cost, and can completely replace imported like products.
Description
Technical field
The present invention relates to a kind of polymer warning tape its preparation method.
Background technology
In recent years along with the develop rapidly of China's city Urbanization Construction, the consumption of high strength warning tape in urban infrastructure is increasing, the high-end warning tape of development high-performance, durable can not only promote the transition and upgrade of conventional plastic processing industry, and the unnecessary accident that produces in urban infrastructure process can be avoided, market outlook are very huge.Clearly claim in 2005 " National Program for Medium-to Long-term Scientific and Technological Development (2006-2020) " the advanced plastic nano material of development and composite product thereof.
The conventional warning tape of current China is main base material with PVC film, is prepared from by rolling process.This warning tape has the characteristic such as good insulation, resistance to combustion, cold-resistant, proof voltage, acid and alkali-resistance, solvent resistant, and can be used for terrain warning alerts region indicates, and color is multiple and adapt to different demands.But due to toxic gas chlorine can be produced in PVC warning tape preparation process, and there is serious aging phenomenon in long-time use, and European and American developed countries progressively eliminate this product.Current high-strength polyolefin warning tape becomes optimum substitute, and in developed countries such as the U.S., Japan, Europe, high performance polyolefine warning tape accounting reaches more than 70%, and China is just at the early-stage.
Conventional P VC warning tape mainly adopts melting coextrusion processes, casting roller impression brush is prepared from, there is poor working environment, the product problems such as easily aging, jaundice variable color intensity is not good in product preparation process, be badly in need of that mechanical property is good, the durable product innovation of product is used for substituting conventional P VC warning tape.
Summary of the invention
Not enough for prior art, the invention provides polymer warning tape that a kind of mechanical property is good, product is durable and preparation method thereof.
To achieve the above object of the invention, the present invention is by the following technical solutions:
One aspect of the present invention provides a kind of polymer warning tape, it is characterized in that it is the polyethylene of high molecular and polyacrylic blend alloy, polyethylene and polyacrylic molecular weight are 1,000,000-250 ten thousand, and wherein poly content is 30%-80%, preferred 50%-70%.
Preferably, poly melting index is 1.8-6.7g/10min, and density is 0.70-1.00g/cm
3, preferred 0.90-0.97g/cm
3; Polyacrylic melting index is 1.5-5.1g/10min, and density is 0.70-1.00g/cm
3, preferred 0.90-0.97g/cm
3.
Preferably, polyethylene and polypropylene are unilateral stretching.
Present invention also offers a kind of preparation method of polymer warning tape, it is characterized in that described method comprise the steps: by polyethylene and polypropylene even in stirrer for mixing respectively, carry out melting co-extrusion, flow casting molding, cooling forming obtains polymer warning tape.
The resistance to light characteristics of film product of the present invention: by the accurate specified requirement of the fast light sighting target of PV1303 5 cycle colour fastness 4 grades.Product is heat-resisting, cold tolerance is very good, and product respectively deposits 48 hours in 110 ± 2 DEG C ,-40 ± 2 DEG C, product without there is shape, visible and (or) affect the change of function in color and surface quality.The tensile strength of warning tape is not less than 25MPa.
Embodiment
Below in conjunction with specific embodiment, the present invention is further described, but does not limit the invention to these embodiments.One skilled in the art would recognize that all alternativess, improvement project and the equivalents that present invention encompasses and may comprise in Claims scope.
Polyethylene and polypropylene is even in stirrer for mixing respectively, and carry out melting co-extrusion, flow casting molding, cooling forming obtains polymer warning tape.Particular case is as shown in table 1.
Table 1
Wherein, the unit of happy and harmonious index is g/10min; Density unit is g/cm
3.
Test the performance of the warning tape material of above-mentioned preparation, concrete outcome is shown in Table 2:
Table 2
Claims (4)
1. a polymer warning tape, it is characterized in that it is the polyethylene of high molecular and polyacrylic blend alloy, polyethylene and polyacrylic molecular weight are 1,000,000-250 ten thousand, and wherein poly content is 30%-80%, preferred 50%-70%.
2. polymer warning tape as claimed in claim 1, it is characterized in that poly melting index is 1.8-6.7g/10min, density is 0.70-1.00g/cm
3, preferred 0.90-0.97g/cm
3; Polyacrylic melting index is 1.5-5.1g/10min, and density is 0.70-1.00g/cm
3, preferred 0.90-0.97g/cm
3.
