高模量聚氨酯密封膏密度

聚氨酯建筑密封膏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）。

Polyurethane building sealant is a two component reaction solidification type, consisting 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).
原理
principle
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。
Base treatment: the sticky surface must be handled neatly (portable cutting machine, grinding wheel, brush, etc.), so that the surface of the coating is exposed to a solid structure layer.
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。
The joint surface must be completely dry, clean and frost free. All dust and cement on the surface must be cleaned and treated cleanly. Rust and protective paint on the metal surface must also be removed. Such structures do not use torch drying.

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.（本公司有配套的各种底涂料供给）。

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. (the company is supporting the various bottom paint supply).
特点
Characteristic
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。
The utility model has the advantages of good abrasion resistance, low softness, softness, wide range of performance adjustment, strong mechanical strength, good adhesive property, good elasticity, excellent resilience, and can be suitable for dynamic seams and deformation joints and expansion joints. Good weather resistance, good oil resistance, aging resistance and low price.
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。同时聚氨酯密封胶耐水性也较差，特别是耐碱水性欠佳。
Polyurethane sealants also have some disadvantages. Such as: not long-term heat; light formula vulnerable to UV aging; single component storage stability by packaging and external influence, usually curing slowly; may produce bubbles and cracks under high temperature environment; many occasions need primer. At the same time, polyurethane sealant is poor in water resistance, especially alkali resistance, poor water quality.
适用范围
Scope of application
该产品使用于土木建筑业、交通运输业、混凝土预制件等建材的连接及施工缝的填充密封。高级道路、桥梁、飞机跑道、地下管道、接头处的连接密封以及隧道和建筑物的伸缩缝与变形缝。
The product is used in the construction of civil engineering, transportation, precast concrete and other construction materials and sealing of construction joints. Connections and seals for advanced roads, bridges, runways, underground pipes, joints, and expansion and deformation joints of tunnels and structures.
注意事项
Matters needing attention
一、建筑物必须保持干燥、干净、无油污。
First, the building must be kept dry, clean and free from oil pollution.
二、在施工前应先将底涂液涂于表面，待表面干燥后把缝隙的两边10mm处贴上50mm宽的防护胶带，以防施工中多余的聚硫胶把构筑物表面弄脏。
Two, before construction, should be applied to the surface of the bottom coating liquid, to dry the surface after the gap on both sides of the 10mm affixed to the 50mm wide protective tape, in case the construction of excess polysulfide glue to the surface of the structure of pollution.
三、把箱内1桶白色聚硫胶（A组份）与1袋黑色固化剂（B组份）充分搅拌均匀，直到无色差为止。
Three, the box 1 barrels of white polysulfide glue (A component) and 1 bags of black curing agent (B component) fully mixing, until there is no color difference so far.
(注：因气候不同B组份应冬季多、夏季少）A：B=10：0.8-1.2，用前应先做小试。
(Note: due to different climate, B group should be more winter, Xia Jishao) A:B=10:0.8-1.2, should be tested before use.
四、把搅拌好的聚硫密封胶用灰刀或挤胶枪填入缝内压实填满，再用≥10cm宽腻子刀把胶刮平。

Four, the polysulfide sealant with grey knife or glue gun to fill the slot fill the well mixed and compacted, more than 10cm wide rubber scraping putty knife.
