Description
Technical Field
The invention relates to the technical field of synthetic resin production, in particular to a high-hardness and corrosion-resistant synthetic resin composition and a preparation method thereof.
Background
Synthetic resin is a kind of high molecular weight polymer synthesized artificially and is a resin with or exceeding the inherent characteristics of natural resin. Astm d883-65T defines synthetic resins as organic materials which are not limited in molecular weight but are often high molecular weight solids, semi-solids or pseudo (quasi) solids, which tend to flow when subjected to stress, often having a softening or melting range and shell-like when broken. Synthetic resins are also basic raw materials for manufacturing synthetic fibers, paints, adhesives, insulating materials, and the like, and widely used resin concrete also uses synthetic resins as cementing materials. Because synthetic resins have significant performance and cost advantages over other competing materials, their use penetrates into various aspects of the national economy. Packaging is the largest market for synthetic resins, and secondarily for construction products. Electronic, electric and automotive are also important fields of application for synthetic resins. Other markets are furniture, toys, recreational products, household appliances, medical products, and the like.
The patent with publication number CN116333244A discloses a synthetic resin, a preparation method and application thereof, which are applied to the field of synthetic resin, and the technical scheme is as follows: the method comprises the following steps: s1, mixing 500-700 parts of formaldehyde, polyvinyl alcohol, 500-240 parts of urea, 160-240 parts of water and ammonia water, and preserving heat for 0.5-1.5 hours at 80-90 ℃; s2, adjusting the pH to 4.8-4.6, adding alkaline substances to adjust the pH to 5-5.3 after 15-30 minutes, adding 150-200 parts of urea and 30-70 parts of melamine, and preserving heat for 15-30 minutes; s3, adding alkaline substances to adjust the pH value to 7-8, adding 250-300 parts of urea, and preserving heat for 20-40 minutes; s4, cooling to 68-72 ℃, adding 100-200 parts of urea, continuously cooling to 55-60 ℃, adding 40-60 parts of ammonia water, cooling to 45-50 ℃, adding 3-8 parts of aldehyde eliminating agent, and discharging after more than 30 minutes; the method has the technical effects that: the residual amount of formaldehyde in the synthetic resin is made to be at a low level.
At present, the strength and corrosion resistance of the existing synthetic resin can not meet the requirements in actual use, the corrosion resistance of the synthetic resin is often subjected to serious tests in humid environments such as heavy rainfall for a long time, the service life of the synthetic resin can be influenced if the corrosion resistance is low, and meanwhile, the resin can not be used in special environments due to cracking caused by poor hardness performance in high-temperature insolation environments, so that the synthetic resin composition with high hardness and corrosion resistance and the preparation method thereof are provided, and the problems are solved.
Disclosure of Invention
