Problems solved by technology

However, aramid 1414 fibers also have defects such as low compressive strength, low UV radiation resistance, and weak bonding between the surface and the resin.
In addition to the inherent properties of the material itself, the influence of the external environment on the material properties cannot be ignored. For aramid 1414, it is mainly the photoaging effect, which causes the material to degrade, age and deteriorate, resulting in the gradual deterioration of the mechanical properties of the product. decline, resulting in brittleness, cracking and yellowing, or even complete damage and cannot be used. Therefore, the safe use of aramid 1414 under the long-term action of light also needs to be solved urgently.
[0008] "China Safety Production Science and Technology" Volume 6 No. 2 published "Safety Research and Development of Aramid Fiber 1414 Under Light Radiation" in April 2010, which described the research status of light resistance of aramid fiber 1414 and light resistance protection technology At present, coating protection measures are mainly used to prevent light from directly irradiating the fabric. Coating materials can be divided into organic UV shielding coatings and inorganic UV shielding coatings. Inorganic UV shielding agents not only have high chemical stability, Thermally stable, non-toxic, non-irritating, safe to use, and it is also a spectral shielding agent, which has a shielding effect on the medium and long waves of ultraviolet rays; while the organic ultraviolet shielding agent has a short wavelength band for shielding ultraviolet rays and has large side effects, which are easy to cause harm to the human body. Chemical allergies, with varying degrees of toxicity and irritation
