Application of 1.1 material theory in anticorrosion adhesive
1) the principle of selecting raw materials
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) technical methods and effects
首先采用表面物理包覆方法均匀分散纳米材料具体应用如下：为了充分发挥纳米材料的优异性能，首先要确保其能在高分子溶液中有良好的分散性。大家在研究中发现，可以借助稳定的分散助剂，通过高速搅拌使高分子吸附在纳米粒子表面上，从而减少范德华力，而且产生一种新的空间位阻斥力，对粒子间的各种缔合力起到减弱或屏蔽作用，粒子间再发生团聚将十分困难，最终得到稳定的分散效果。其次提高防腐胶的机械性能（如图1所示）添加一定粒径一定量n-SiO2，复旦大学武利民等在《n-SiO2在高固体分聚氨酯涂料中的应用》一文中先容了纳米n-SiO2时，对涂层拉伸强度和断裂伸长率的影响。再次提高防腐胶储存性与施工性。再有需要提高抗老化性能。n- SiO2具有极强的紫外反射能力，对波长400nm以内的紫外反射率达70%以上，因此是一种好的抗老化的添加剂；n- SiO2对紫外线的屏蔽是以吸取和散射为主，经紫外分光广度仪检测，它对200nm以上的紫外光线的屏蔽率高达99.99%，因此大家可以填充一定量的纳米材料到防腐胶中提高防腐胶的抗老化能力，以便适应海洋重防腐的要求。
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"  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.
