The two-component polysulfide sealant is made of liquid polysulfide rubber, which is made of tackifier resin, vulcanizing agent, accelerator, reinforcing agent and so on. This kind of sealant has excellent properties such as fuel oil, hydraulic oil, water and various chemicals, as well as heat resistance and atmospheric aging resistance. Generally curable type. The components can be divided into two components (or three components) and one component type. The process of premixing grinding filling is adopted in the process. Two component polysulfide sealant is the most advanced waterproof material in the world and in china. In foreign developed countries, the high-rise building adopts polysulfide building paste wall joint sealing. Polysulfide sealing paste is suitable for long-term immersion building joint sealing, and concrete bonding performance, such as: underground waterproof joint, runway, water pollution, sewage pool, underground engineering, large-scale water conservancy projects adopt polysulfide sealant, it has anti-aging, durability, air tightness and water resistance good adhesion, high elongation rubber shape with high elasticity, has been in the domestic part of large reservoir, storage tank, sewage tank, underground engineering, has been using this product by engineering and technical personnel.

1.双组份聚氨酯建筑密封胶属双组份反应固化型，有A、B两组份组成。A组分为乳白色或浅黄色粘稠状聚氨酯预聚体，B组分为固化剂与助剂等混合脱水而成的黑色膏状体或液体，固化后具有一定的弹性及粘结性，（A组份：B组份=10：0.8～1.2）。

1. two-component polyurethane building sealant is a two component reactive curing type, which consists of two components of A and B. The A component is milky white or light yellow viscous polyurethane prepolymer, and group B as curing agent and additives mixed dehydration black paste or liquid, after curing with elasticity and adhesion of the (A group: B group =10:0.8 ~ 1.2).

2.双组份聚氨酯建筑密封胶原理：双组份聚氨酯密封胶基层处理，被粘面必须进行整齐处理（可用手提切割机，砂轮，刚刷等），使涂胶面露出牢固的结构层。接缝表面必须保证完全干燥、清洁、无霜。表面所有灰尘和水泥稀浆必须清刷处理干净。金属表面的锈层及保护漆也需除去。如构筑物不干，可用喷灯烘干。多孔表面涂胶前需先涂底涂料，底涂料只需刷涂一薄层，待其表面不粘手后方可涂密封胶嵌缝。

2. double component polyurethane sealant for building principle: a two-component polyurethane sealant base processing, must be neat with sticky surface (available portable cutting machine, grinding wheel, etc., just brush the glue) with solid structure layer. The joint surface must be completely dry, clean and frost free. All dust and cement slurry on the surface must be cleaned and cleaned. Rust and protective paint on metal surface also need to be removed. Such structures do not use torch drying. Before the first coating porous surface coating primer, primer only need to brush a thin layer, the surface is not sticky rear can be coated with sealant.

3.双组份聚氨酯建筑密封胶特点：

Characteristics of 3. two-component polyurethane building sealant:

双组份聚氨酯密封胶具备优良的耐磨性、低温柔软性，性能可调节范围较广，机械强度大，粘接性好，弹性好，具有优良的复原性，可适合动态接缝和变形缝、伸缩缝。耐候性好，耐油性优良，耐生物老化且价格低廉。聚氨酯密封胶也有一些缺点。如：不能长期耐热，浅色配方容易受紫外光老化，单组分胶贮存稳定性受包装及外界影响较大，通常固化较慢，高温热环境下可能产生气泡和裂纹，许多场合需要底涂。同时双组份聚氨酯密封胶耐水性也较差，特别是耐碱水性欠佳。

Two component polyurethane sealant has excellent abrasion resistance, low temperature flexibility, performance can be adjusted in a wide range, high mechanical strength, good adhesion, good elasticity, has excellent resilience, suitable for dynamic deformation joints, expansion joints and seams. Good weather resistance, good oil resistance, aging resistance and low price. Polyurethane sealant also has some disadvantages. Such as: not long-term heat, light formula is vulnerable to UV aging, single component storage stability by packaging and external influence, usually curing slower, may produce bubbles and cracks of high temperature heat environment, many occasions need primer. At the same time, two component polyurethane sealant is poor in water resistance, especially alkaline water resistance.
