【摘要】：通過對鋁合金及聚甲基丙烯酸甲酯(PMMA)基底涂覆不同彈性涂層進行表面改性,研究了涂層彈性對基底結(jié)冰附著強度的作用。用單組份室溫硫化硅橡膠WH-705與BOPP進行對比。采用水杯制冰結(jié)冰強度測試試驗法,以結(jié)冰切向附著力為指標,測量鋁合金和PMMA兩種材料(典型金屬和非金屬材料)基底表面未涂覆和涂覆彈性涂層后的結(jié)冰附著強度。試驗結(jié)果表明,相對于標準基底,涂覆彈性涂層后基底表面結(jié)冰強度有顯著變化。其中,涂覆硫化硅橡膠的鋁表面結(jié)冰強度降低73.27%,PMMA表面降低14.85%。分析表明,涂層的彈性系數(shù)、分布規(guī)律等對結(jié)冰附著強度的影響顯著。本文研究可為彈性涂層在防除冰方面的實際應(yīng)用提供依據(jù)。
[Abstract]:Surface modification of aluminum alloy and polymethyl methacrylate (PMMA) substrate with different elastic coatings was carried out. The effect of coating elasticity on the adhesion strength of substrate ice was studied. The one-component room temperature vulcanized silicone rubber (WH-705) was compared with BOPP. The icing adhesion strength of aluminum alloy and PMMA material (typical metal and non-metallic material) on the surface of uncoated and elastic coating was measured. The icing strength of aluminum coated with vulcanized silicone rubber decreases by 73.27% and 14.85% by PMMA. The analysis shows that the elastic coefficient of the coating is reduced by 14.85%. The distribution law has a significant effect on the icing adhesion strength. The study in this paper can provide the basis for the practical application of elastic coating in anti-icing.
