環氧地坪漆顏填料主要是鈦白粉、氧化鐵紅、石英粉等,它們的比重比較大,在儲存一段時間后往往就會沉到油漆桶底部了。分散劑是將添加在南京環氧地坪漆內的顏料、填料潤濕和分散,以保持顏料、填料在環氧地坪漆內的穩定性。分散劑的存在對環氧地坪漆非常重要,否在,環氧地坪漆材料在存儲過程中就會發生沉淀,影響環氧地坪材料的正常使用。分散劑如何提高環氧地坪漆的穩定性:
Epoxy floor paint fillers are mainly titanium dioxide, iron oxide red, quartz powder, etc. Their proportion is relatively large, after storage for a period of time, they often sink to the bottom of the paint barrel. The dispersant is to wet and disperse the pigments and fillers added in the epoxy floor paint to maintain the stability of the pigments and fillers in the floor paint. The existence of dispersant is very important for epoxy floor paint. Whether the epoxy floor paint material will precipitate in the storage process will affect the normal use of the floor paint material. How to improve the stability of epoxy floor paint with dispersants:
1、保持填料粒子懸浮;
1. Keep the filler particles suspended.
分散劑通過結構內的活性基團,將細小的填料和溶劑吸附在一起,形成吸附層,依靠熵斥力,使填料粒子在地坪漆內長時間處于分散懸浮狀態太。
The dispersant adsorbs fine fillers and solvents together through the active groups in the structure to form an adsorption layer. Depending on the entropy repulsion force, the filler particles stay in the dispersed suspension state for a long time in the floor paint.
2、提高各組分親和力;
2. Enhance the affinity of each component.
鏈接涂料和填料粒子,提高涂料內各組分間的親和力,降低涂料地體的表面張力,一方面能提高地坪漆在分散和儲存過程中的穩定性,一方面還能改善地坪漆涂膜流平性的性能,并對浮色發光,色澤遮蓋方面提高強化。
Linking coatings and filler particles can improve the affinity of each component in the paint and reduce the surface tension of the paint floor. On the one hand, it can improve the stability of the floor paint in the process of dispersion and storage, on the other hand, it can improve the leveling performance of the floor paint film, and enhance the float luminescence and color covering.
3、平衡外力。
3. Balance external forces.
外力一方面有空氣氣壓,一方面有重力,會導致地坪漆內的各種粒子下沉,最終形成沉淀。而分散劑可以對細小粒子產生穩定作用
On the one hand, the external force has air pressure, on the other hand, there is gravity, which will cause various particles in the floor paint to sink and eventually form precipitation. Dispersants can stabilize fine particles.
分散劑在環氧地坪漆材料中的作用:
The role of dispersants in epoxy floor paint materials:
1、提升光澤,增加流平效果。即一定的平整度即可.
1. Improve gloss and leveling effect. That is to say, a certain smoothness is enough.
2、防止浮色發花.
2. Prevent float and blossom.
3、提高著色力注意著色力在自動調色系統中并非越高越好.
3. Improving the attention of shading is not the better in the automatic shading system.
4、降低粘度,增加顏料載入量.
4. Reduce the viscosity and increase the loading of pigments.
5、減少絮凝是這樣的,但越細粒子表面能越高,需要越高吸附強度的分散劑,但吸附強度太高的分散劑可能造成對涂膜性能的不利.
5. Reducing flocculation is like this, but the finer the surface energy of the particles is, the higher the dispersant of adsorption strength is needed, but the dispersant with too high adsorption strength may cause disadvantage to the performance of the film.
6、增加貯藏穩定性其實原因和上相似,一旦分散劑穩定強度不夠,反而貯藏穩定性變差。
6. The reasons for increasing storage stability are similar to those above. Once the stability strength of dispersant is insufficient, the storage stability becomes worse.
7、增加展色性,增加顏色飽和度、增加透明度(有機顏料)或遮蓋力(無機顏料).
7. Increase color development, color saturation, transparency (organic pigments) or covering power (inorganic pigments).
