Description
The invention relates to a Chinese patent application with the application number 2020113901497 and the name of ultraviolet-resistant and high-low temperature impact-resistant thin-wall high-length-diameter-ratio polypropylene ribbon, which is divided into patent applications of 12 months and 2 days in 2020.
Technical Field
The invention belongs to the technical field of polymer materials and processing, and particularly relates to a thin-wall high-length-diameter-ratio plastic product, in particular to an ultraviolet-resistant polypropylene ribbon.
Background
Thin-wall plastic molding technology is a relative concept, and the definition in the industry is divided into three cases: (1) The ratio L/T of the flow length to the thickness, namely the ratio of the flow length L of the melt entering the die to the furthest point of the cavity which the melt must fill to the corresponding average wall thickness T is more than 100 or 150, and the injection molding is thin-wall high-length-diameter-ratio injection molding; (2) The thickness of the molded plastic part is less than 1mm, and the projection area of the molded plastic part is 50cm 2 The above injection molding method; (3) The wall thickness of the molded plastic part is less than 1mm (or 1.5 mm), or the injection molding of t/d (plastic part thickness t, plastic part diameter d, for disc type plastic part) below 0.05 is defined as thin-wall injection molding.
At present, the domestic thin-wall plastic molding technology is applied to the fields of food containers, medicine boxes, cosmetics, stationery and the like, and belongs to injection molding with small thin-wall length-diameter ratio. In the aspect of thin-wall high-length-diameter-ratio injection molding, because of the thin-wall high-length-diameter-ratio injection molding technology, higher requirements are put forward on equipment and an injection molding process, and meanwhile, higher requirements are put forward on high fluidity of raw materials, while the thin-wall low-length-diameter-ratio injection molding has lower fluidity requirements on the raw materials. Typical cases for the manufacture of thin-walled high aspect ratio plastic articles are the manufacture of thin-walled high aspect ratio ties.
Polypropylene is a pure carbon chain polymer containing neither polar groups nor chemically active groups and has many excellent properties such as: the polypropylene product has increasingly wide application in production and life, such as a thin-wall high-length-diameter-ratio ribbon product, the most widely used is nylon 6 or nylon 66 ribbon at present, because the strength, weather resistance and the like of nylon 6 or nylon 66 are better, but the cost of nylon 6 or nylon 66 is relatively higher, and the polypropylene product has certain hygroscopicity (the saturated water absorption of nylon 66 reaches 4.6 percent, the saturated water absorption of nylon 6 exceeds 8 percent, and the product performance degradation caused by nylon water absorption is extremely serious along with the rise of temperature), the mechanical property of the product is obviously influenced by the relative humidity of the environment, the polypropylene does not have hygroscopicity (the saturated water absorption of polypropylene is lower than 0.4 percent, and the product performance is hardly influenced by the humidity and the temperature of the environment (in a suitable temperature range), and the polypropylene has more advantages than the nylon product in some specific application fields; on the other hand, polypropylene has lower price than nylon, less impact on market environment, stable price and obvious advantages in civil fields, so if polypropylene material is used for making polypropylene ribbon, the polypropylene ribbon is expected to replace nylon 6 or nylon 66 ribbon in some fields.
However, in chemical structure, the polypropylene chain segment contains a large number of tertiary carbon atoms, and under the illumination condition, particularly under the ultraviolet irradiation condition, the polypropylene is easy to undergo photooxidation degradation, so that the polymer chain segment is broken, and the mechanical property is deteriorated. Qian Xin et al (flame retardant materials and techniques, second 2006) showed that placing polypropylene in a test chamber at a fluorescent UV lamp power of 320W and a UV wavelength of 280-400 nm, irradiating a sample of polypropylene at a chamber temperature of 60℃for 4 hours each time interval for 4 hours, and after 250 hours of the test, decreasing the tensile strength of polypropylene from an initial 35.6MPa to 31.4MPa. Yu Jianying et al (journal of materials research, volume 13, phase 5) showed that after uv irradiation, the polypropylene was rapidly photooxidized for 24 hours with oxidized carbon atoms at the interface accounting for 15.96% of the total carbon atoms, and for 72 hours and 120 hours with oxidized carbon atoms reaching 31.22% and 50.58%, respectively. The introduced oxygen-containing group is mainly single bond oxygen (C-O-C, C-OH) after 24 hours of irradiation, and the proportion of double bond oxygen existing in the form of carbonyl and carboxyl is obviously increased along with the extension of irradiation time. In the using process of the ribbon, various different working conditions are inevitably encountered, such as the irradiation of ultraviolet rays when the ribbon is used outdoors; as mentioned above, the existing polypropylene plastic has a special structure, the ultraviolet resistance and the mechanical property can not meet the special condition requirements, and the product quality is unstable, thereby influencing the performance of the binding belt made of polypropylene.
At present, although the ultraviolet resistance of polypropylene can be improved by adding zinc oxide, carbon black or similar milky white fillers in the prior art, the addition of the substances can lead to the loss of the transparency of polypropylene, and downstream customers have certain demands on the transparency of the product; meanwhile, for severe environments, such as areas with larger temperature difference, the cable tie is required to have high and low temperature impact resistance, and the current general polypropylene plastic is difficult to meet the requirement.
Disclosure of Invention
The invention aims to solve the technical problems of overcoming one or more defects in the prior art and providing an improved thin-wall high-length-diameter-ratio polypropylene ribbon capable of obviously improving ultraviolet resistance without reducing the transparency of the product.
In the invention, the thin wall refers to the wall thickness of less than 1.5mm, or t/d (the thickness t of the plastic part, the diameter d of the plastic part and the diameter d of the disc-shaped plastic part) is less than 0.05. The high aspect ratio refers to the ratio L/T of flow length to thickness, i.e. the ratio of flow length L from the melt into the mold to the furthest point of the cavity that the melt has to fill to the corresponding average wall thickness T, is above 100, specifically the ratio of length to thickness of the article is above 100.
