    环氧地坪漆的使用效果与哪些因素有关

    环氧地坪漆产品粘度较高,存在诱导期,与环氧树脂的相容性差,固化热稳定性低,粘结性好,强度和韧性好,主要用于高固体分涂料、密封剂、电缆连接剂、粘合剂、酯.环胺环状脂肪族酯,即环胺低粘度.寻找固化光,光泽好,保色性好,与聚酰胺相比,耐化学性好,油漆不白,不需要诱导期,但韧性差,固化活性低,固化后需要加热能力,仅在加入促进剂或改性条件后才能进行.室温固化.

    Epoxy floor paint products have high viscosity, induction period, poor compatibility with epoxy resin, low curing thermal stability, good adhesion, strength and toughness, mainly used in high solid paint, sealant, cable connector, adhesive, ester, cyclic amine aliphatic ester, that is, cyclic amine low viscosity. Compared with polyamide, it has good chemical resistance, non-white paint, no induction period, but poor toughness, low curing activity, need heating ability after curing, and can be cured at room temperature only after adding accelerator or modification conditions.

    耐腐蚀涂料用芳香族胺与间苯二胺,这种固化剂除了具有苯系二甲胺具有部分脂肪族结构的液体特性外,其它都是常温固体,所以与树脂混合,一般要加热固化,使用MILL.Y用于加热固化过程中,涂料也可作为改性胺类固化剂的原料.

    Aromatic amines and m-phenylenediamine are used in corrosion-resistant coatings. Apart from phenylene dimethylamine which has some aliphatic structure, the curing agent is a normal temperature solid. Therefore, when mixed with resin, it is usually cured by heating. MILL.Y is used in the curing process, and the coating can also be used as the raw material of modified amine curing agent.

    一般来说,单一的多胺小分子量、挥发性、毒性、交联密度大,反应后与环氧树脂固化脆性大,耐冲击性强,一般不是单一的多胺,特别是脂肪族单分子量小、易挥发、毒性大、反应快.环氧树脂交联密度大,地板漆固化严重的白色涂料.

    Generally speaking, a single polyamine has small molecular weight, volatility, toxicity and high cross-linking density. After reaction, it is cured with epoxy resin with high brittleness and impact resistance. Generally, it is not a single polyamine, especially aliphatic monoamine with small molecular weight, volatility, high toxicity and fast reaction.

    减少未反应的多胺的量可吸收空气中的水分,涂层表面出汗,使单胺作为环氧树脂固化剂的缺点,限制了其在涂料层中的应用,以克服脆性胺固化剂、有机硅高-耐温漆耐冲击性差、耐候性差、毒性大,必须进一步改性为胺类固化剂,以达到无毒或低毒.

    Reducing the amount of unreacted polyamines can absorb moisture in the air and sweat the surface of the coating, which limits the application of monoamines as curing agents for epoxy resins. In order to overcome the shortcomings of brittle amine curing agents and silicone high-temperature-resistant paints, such as poor impact resistance, poor weatherability and high toxicity, it is necessary to further modify monoamines as curing agents. To achieve non-toxic or low toxicity.

    在温室固化条件下,环氧固化剂的环氧富锌底漆一般由于反应过度,产生加合物分子量大,沸点和助剂、粘度增加,皮肤和粘膜的刺激性大大降低,由于TH的缘故.E加合物固化一般固化反应较快,醇酸漆固化物的力学性能由原来的多胺化学性质差一点.

    Under the greenhouse curing condition, the epoxy zinc-rich primer with epoxy curing agent usually has high molecular weight, high boiling point, auxiliaries and viscosities due to excessive reaction, and the irritation of skin and mucous membrane is greatly reduced. Because of TH, the curing reaction of E-adduct is usually fast, and the mechanical properties of alkyd paint cured are changed from the original polyamination. The nature of learning is a bit different.
