助剂是环氧地坪涂料中不可欠缺的成分,惯用来改良涂料表观性能以及机器性能,或许赋予涂料特定的性能.在地坪涂料中惯用的助剂有分布剂、消泡剂、流平剂、流变剂,尚有防静电、防滑、消光性能性助剂.在地坪涂料中常见的毛病重点有缩孔、针孔、橘皮、失光、缩变以及失笑,由于分布不和而造成的发花以及浮色,色泽不均,由于未流平而造成表面不均等问题.

Auxiliaries are indispensable ingredients in epoxy floor coatings. They are used to improve the apparent and mechanical properties of the coatings, and may give the coatings specific properties. The focus of the disease is shrinkage, pinholes, orange peel, loss of light, shrinkage and laughter, due to the distribution of inconsistent flowers and float, uneven color, uneven surface due to uneven.

这些问题通常需求适度的助剂来铲除.,地坪涂料助剂重点包含--润泽分布剂:高分子润泽分布剂大多是聚氨酯、聚丙烯酸酯、聚酯等嵌段聚合物或接枝聚合物,分子带有多个吸附基团结构以及溶剂化链段结构,在颜料表面造成较厚且较安稳的吸附层,空间位阻以及熵斥力大、分布系统安稳性好.

These problems usually need moderate additives to eradicate. Floor coatings additives include - wetting distributors: polymer wetting distributors are mostly polyurethane, polyacrylate, polyester and other block polymers or graft polymers, the molecules with multiple adsorption groups and solvation chain structure, resulting in a thicker and thicker surface of the pigment. The more stable adsorption layer, the steric hindrance and entropy repulsion, and the stability of the distribution system are good.

消泡剂:在涂料配方中有不少对泡沫造成及其安稳的要素,且参与的多种助剂不少属于表面活性剂,对气泡起安稳作用,防泡以及消泡是涂料制作以及施工过程中不可轻视的问题,溶剂型涂料中消泡问题毋宁水性涂料要紧、但也需求造成充足的看重.

Defoamers: there are many factors that cause bubbles and their stability in the formulation of coatings. Many of the auxiliaries are surfactants, which play an important role in stabilizing bubbles. Antifoaming and defoaming are problems that can not be ignored in paints production and construction. Enough attention is paid to it.

流平剂:对地坪涂料而言,涂料的流平性是一个很紧要的性能指标,流平性与系统的溶剂干系很大,流平性不和时不妨适度参与高沸点的溶剂来改良,不然过多的高沸点长久间残留在漆膜里,要紧下降漆膜的机器强度.

Leveling agent: For floor coatings, the leveling of the coating is a very important performance index, leveling and the system of solvent is very large, leveling and may be moderately involved in high boiling point solvent to improve, or excessive high boiling point resides in the film for a long time, to reduce the mechanical strength of the film.

流变助剂:料的制作、施工以及成膜对系统剪切速度的要求差异,平常要求涂料拥有肯定的触变性,对地坪涂料而言,流变助剂的作用重点是预防涂料在储备时颜料沉除召集,并改良涂刷性.

Rheological auxiliaries: the production of materials, construction and film forming requirements for the shear rate of the system are different, usually required to have a positive thixotropy coating, floor coating, rheological auxiliaries, the role of the focus is to prevent the coating in reserve when the pigments sink, and improve the brushability.

由于环氧地坪涂料拥有优异的性能以及装束功效,被平凡使用在工场、病院、私塾、办公室及大型公共场合等方面.

Epoxy floor coatings are used in factories, hospitals, private schools, offices and large public places because of their excellent performance and dressing efficiency.
