对防静电地坪而言,首先要考虑到涂层的防静电指标;其次,还有抗压强度、抗拉强度和耐磨性,以及通常的耐化学品性能。因此,在配方设计时基本上选用环氧树脂作为基料,添加导电物质、填料、溶剂及助剂,制成防静电地坪涂料。下面我们一起了解一下环氧树脂的特性以及地坪施工
For anti-static floor, the anti-static index of coating should be considered firstly; secondly, compressive strength, tensile strength and wear resistance, as well as the usual chemical resistance. Therefore, in the formulation design, epoxy resin is basically used as binder, conductive materials, fillers, solvents and additives are added to make anti-static floor coatings. Now let's have a look at the properties of epoxy resin and floor construction.

环氧树脂的特性
Properties of epoxy resin
1、 形式多样。各种树脂、固化剂、改性剂体系几乎可以适应各种应用对形式提出的要求,其范围可以从极低的粘度到高熔点固体,固化方便。选用各种不同的固化剂,环氧树脂体系几乎可以在0~180℃温度范围内固化。
1, various forms. Various resins, curing agents, modifiers can almost meet the requirements of various applications on the form, its range can be from very low viscosity to high melting point solid, easy curing. With various curing agents, the epoxy resin system can almost solidify within 0~180 C temperature range.
2、 耐霉菌。固化的环氧树脂体系耐大多数霉菌,可以在苛刻的热带条件下使用。
2, mould resistance. The cured epoxy system is resistant to most molds and can be used in harsh tropical conditions.
3、 粘附力强。环氧树脂分子链中固有的极性羟基和醚键的存在,使其对各种物质具有很高的粘附力。环氧树脂固化时的收缩性低,产生的内应力小,这也有助于提高粘附强度,尺寸稳定性。上述的许多性能的综合,使环氧树脂体系具有突出的尺寸稳定性和耐久性
3. Strong adhesion. The existence of polar hydroxyl and ether bonds in the molecular chain of epoxy resin makes it have high adhesion to various substances. The shrinkage of epoxy resin curing is low and the internal stress is small, which also helps to improve the adhesion strength and dimensional stability. The synthesis of many of the above properties makes the epoxy system have outstanding dimensional stability and durability.
4、 化学稳定性。通常,固化后的环氧树脂体系具有优良的耐碱性、耐酸性和耐溶剂性。像固化环氧体系的其它性能一样,化学稳定性也取决于所选用的树脂和固化剂。适当地选用环氧树脂和固化剂,可以使其具有特殊的化学稳定性能。
4, chemical stability. Generally, the cured epoxy system has excellent alkali resistance, acid resistance and solvent resistance. Like other properties of cured epoxy systems, chemical stability depends on the resin and curing agent chosen. Proper choice of epoxy and curing agents can give them special chemical stability.
5、 收缩性低。环氧树脂和所用的固化剂的反应是通过直接加成反应或树脂分子中环氧基的开环聚合反应来进行的,没有水或其它挥发性副产物放出。它们和不饱和聚酯树脂、酚醛树脂相比,在固化过程中显示出很低的收缩性(小于2%)。
5, low shrinkage. The reaction between epoxy resin and curing agent is carried out by direct addition reaction or ring opening polymerization of epoxy group in resin molecule. No water or other volatile by-products are released. Compared with unsaturated polyester resin and phenolic resin, they exhibit very low shrinkage (less than 2%) during curing.
6、 力学性能。固化后的环氧树脂体系具有优良的力学性能,电性能。固化后的环氧树脂体系是一种具有高介电性能、耐表面漏电、耐电弧的优良绝缘材料。
6. Mechanical properties. The cured epoxy resin system has excellent mechanical and electrical properties. The cured epoxy resin system is an excellent insulating material with high dielectric properties, surface leakage resistance and arc resistance.
