Application of 1.1 material theory in anticorrosion adhesive

1）選擇（zé）原材料的原則

1) the principle of selecting raw materials

基料分子要有（yǒu）極性較強的化學鍵（jiàn），即分子末端具備有活潑性基團，如羥基、羧基、酚基、醚鍵等（děng）；基料具有複合性能（包括化學性（xìng）能和物理性能）。

The base material has a strong chemical bond, that is, the end of the molecule has active groups, such as hydroxyl, carboxyl, phenolic, ether bond, etc., and the base material has composite properties (including chemical and physical properties).

2）技術方法（fǎ）及成效

2) technical methods and effects

首先采用表麵物理包覆方法均勻分散納米材料具體應用如（rú）下：為（wéi）了充分發揮納米材料的優異性能，首先要（yào）確保其能在高分子溶液中有良好的分散性。我們在研究中（zhōng）發現，可以借助穩定的分散（sàn）助劑，通過高速攪拌使高分子吸附（fù）在納米粒子（zǐ）表麵上（shàng），從而減少範德（dé）華（huá）力（lì），而且產生一種新的空間位阻斥力，對粒子間的各（gè）種締合力起到減弱（ruò）或屏蔽作用，粒子間再發（fā）生團聚將十分困（kùn）難，最終得到穩定的分散效果。其次提（tí）高防（fáng）腐膠的機械性（xìng）能（néng）（如圖1所示）添加一定粒徑一定量n-SiO2，複旦大學武利民等在《n-SiO2在高固體分聚氨酯塗料中的應用》[1]一文中介紹了納米n-SiO2時，對塗（tú）層（céng）拉伸強度和（hé）斷裂伸長（zhǎng）率的影響。再次提高（gāo）防腐膠儲存性與施工性。再有需要提高抗老化性能。n- SiO2具有極強的紫外反射能力，對波長400nm以內的紫外反射率達70%以上，因此是一種好的抗老化的添加劑；n- SiO2對紫外線（xiàn）的屏蔽是以吸收和散射為主（zhǔ），經紫外分光廣度儀檢測，它對（duì）200nm以上（shàng）的紫外光線的屏蔽率高達99.99%，因此我們可以填充一定量的納米材料到防腐膠（jiāo）中提（tí）高防腐膠的抗老化能力（lì），以便適應海洋重（chóng）防腐的（de）要（yào）求。

Firstly, the surface physics coating method is used to evenly disperse nano materials. The specific applications are as follows: in order to give full play to the excellent properties of nanomaterials, it is necessary to ensure that it has good dispersion in polymer solution. In our study we found that with dispersant stability, through high speed stirring to polymer adsorption on the surface of nanoparticles, thereby reducing the Fan Dehua force, and create a kind of new steric repulsion to weaken or shielding effect to the various association between particles together, then agglomerate particles will be very difficult, and ultimately to get stable dispersion effect. Secondly, improve the mechanical properties of anticorrosive glue (as shown in Figure 1) to add a certain particle size of a certain amount of n-SiO2 and Wu Limin of Fudan University in "n-SiO2 in high solid polyurethane coatings application" [1] is introduced in this paper, nano n-SiO2, coating effect on the tensile strength and elongation at break. Improve the storage and construction of anticorrosive adhesive again. There is a need to improve aging resistance. N- SiO2 has a strong ability of UV reflection, UV reflectance on the wavelength less than 400nm is more than 70%, so it is an excellent anti-aging additives; shielding n- SiO2 on ultraviolet by absorption and scattering, the UV shielding of breadth instrument, it more than 200nm UV light rate as high as 99.99%, improve the anti-aging ability of anticorrosive glue so we can be filled with a certain amount of nano materials to the anticorrosive glue, so as to adapt to the requirements of heavy duty anticorrosion.
