水溶剂型
Water Solvent Form
在这类涂料中，作为主要成膜物质的高分子溶解于有机溶剂中，成为溶液。高分子材料以分子状态存在于溶液（涂料）中。该类涂料具有以下特性：
In this kind of coatings, the polymer as the main film-forming substance dissolves in organic solvents and becomes a solution. Polymer materials exist in solution (paint) in molecular state. The coatings have the following characteristics:
① 通过溶剂挥发，经过高分子物质分子链接触、搭接等过程而结膜；
(1) The conjunctiva is formed by solvent evaporation, molecular linking, contact and lapping of macromolecule substances.
② 涂料干燥快结膜较薄而致密；
(2) Coatings dry fast conjunctiva is thinner and denser;
③ 生产工艺较简易，涂料贮存稳定性较好；
(3) The production process is simple and the storage stability of coatings is good.
④ 易燃、易爆、有毒，生产、贮运及使用时要注意安全；
4. Flammable, explosive and toxic. Safety should be paid attention to in production, storage, transportation and use.
⑤ 由于溶剂挥发，施工时对环境有一定污染。
Owing to the volatilization of solvents, the environment is polluted to a certain extent during construction.
⑵水乳型
(2) Emulsion type
这类涂料作为主要成膜物质的高分子材料以极微小的颗粒（而不是呈分子状态）稳定悬浮（而不是溶解）在水中，成为乳液状涂料。该类涂料具有以下特征：
These coatings, as the main polymer materials, are suspended in water (rather than dissolved) in tiny particles (rather than molecular states) and become emulsion like coatings in water. This kind of paint has the following characteristics:
① 通过水分蒸发，经过固体微粒接近、接触、变形等过程而结膜；
The conjunctiva is formed by evaporation of water, approaching, contacting and deforming of solid particles.
② 涂料干燥较慢，一次成膜的致密性较溶剂型涂料低，一般不宜在5℃以下施工；
(2) Coatings are dried slowly, and the density of one-time film formation is lower than that of solvent-based coatings. Generally, it is not suitable to construct under 5 C.
③ 贮存期一般不超过半年；
(3) The storage period generally does not exceed half a year;
④ 可在稍为潮湿的基层上施工；
It can be constructed on slightly damp foundation.
