1.1 MCT喷涂高分子橡胶沥青防水涂料施工与卷材防水、传统涂膜防水相比的技术优点：

It has innovated the construction technology and construction method of the traditional waterproof materials, and opened the new era of the transition from the "coil era" to the "liquid rubber age".

MCT喷涂速凝防水材料是一种集防水、防渗、防腐、防护于一体的多功能防水涂料.它采用超细悬浮微乳型阴离子改性乳化沥青和合成高分子聚合物（A组份）与特种固化剂（B组份）混合后生成高弹性防水、防腐涂膜的防水涂料。施工采取冷制冷喷技术，在工程现场采用专用设备直接喷涂。A、B双组分材料在喷枪口外扇形交叉、雾化并高速混合后，到达基面时瞬间破乳、迅速固化，形成致密、连续、完整、类似橡胶的涂膜，真正实现“皮肤式”橡胶防水涂层。该材料以其具有高延展性、抗冲击性、耐腐蚀、耐老化，能够有效地起到抗混凝土开裂，特别适用于异型结构、复杂结构和易发生变形的地下、屋面、隧道、河道防水节点部位.

MCT sprayed fast condensate waterproof material is a multifunctional waterproof coating, which integrates waterproof, anti-corrosion, anticorrosion and protection. It uses superfine suspended microemulsion anionic modified emulsified bitumen and synthetic polymer (A component) and special curing agent (B component) to produce waterproof and anticorrosive coating. Cold and cold spray technology is adopted in the construction, and the special equipment is directly sprayed on the project site. When the A and B double component materials are crossed, atomized and mixed at high speed outside the spray gun, when they arrive at the base surface, they instantly break down and solidify quickly to form a dense, continuous, complete and similar rubber coating, which truly realizes the "skin type" rubber waterproof coating. The material can effectively resist concrete cracking because of its high ductility, impact resistance, corrosion resistance and aging resistance. It is especially suitable for the parts of underground, roof, tunnel and river waterproofing joints with abnormal structure, complex structure and easy deformation.

1.2 合成高分子液体橡胶的特性.

1.2 the properties of synthetic polymer liquid rubber.

1.2.1 超高弹性

1.2.1 super high elasticity

防水涂料的弹性涂膜伸长率可达1200%以上.恢复率达90%以上，能够有效解决各种构筑物因应力变形、膨胀开裂、穿刺或连接不牢等造成的渗漏、锈蚀等问题。

The elastic coating elongation of the waterproof coating can reach more than 1200% and the recovery rate is above 90%. It can effectively solve the problems of leakage and rust caused by the stress and deformation, the expansion and cracking, the puncture or the poor connection.

1.2.2 超高的耐候性

High weatherability of 1.2.2

高分子液体橡胶成膜后不受气温影响.在-40℃寒冷气候条件下也不会脆断，在150℃高温条件下不流淌。

Polymer liquid rubber is not affected by air temperature after film forming. It will not brittle fracture at -40 C and cold climate, and it will not flow at 150 C high temperature.

1.2.3 卓越的附着性

1.2.3 excellent adhesion

可以依附在混凝土、土工布、钢铁、木材、金属等多种材料表面，不起层，不剥离，不脱落，对基层起到良好的保护作用。

It can be attached to the surface of concrete, geotextile, steel, wood, metal and other materials. It does not rise, does not peel off, and does not fall off. It has a good protective effect on the base.

1.2.4 蠕变抗裂性

1.2.4 creep cracking resistance

高分子液体橡胶通过自身柔性的蠕变，消除基层应力对防水层的影响。当基层变形涂层受到拉伸时，粘结层的蠕变可以使受到的应力得以释放.不会使防水层因基层变形而出现开裂。同时，也不会因长期处于高应力的作用下而加速老化。

Polymer liquid rubber eliminates the influence of base stress on waterproof layer through its own flexible creep. When the base deformation coating is stretched, the creep of the bonding layer can release the stress. It will not cause cracks in the waterproof layer due to the deformation of the base. At the same time, it will not accelerate aging due to long-term high stress.

1.2.5 自愈合性

1.2.5 self healing

高分子液体橡胶防水层与基面结合处出现裂纹、破损或被外物穿刺后，胶膜层会往裂纹或孔洞处蠕动，以消除胶膜层在孔洞处的内应力，并堵住缺陷处，阻止水分通过，防止“窜水”现象产生，提高防水的可靠度。

After the crack, breakage or puncture of the surface of the polymer liquid rubber waterproof layer and the base surface, the adhesive film will creep in the crack or hole to eliminate the internal stress of the diaphragm in the hole, stop the defect, prevent the water passing through, prevent the "water channeling" and improve the reliability of the waterproof.

1.2.6 防窜水性

Anti channeling resistance of 1.2.6

防止窜水需要通过满粘来解决。由于施工基面微观结构不平整.普通防水卷材施工其粘结料只能粘住基面的凸出部位.虽然表面看起来粘结得较为牢固，实际上基面上大大小小的凹坑都是窜水的通道.而通过喷涂施工的高分子液体橡胶防水层，完全可以与基面达到满粘效果。

The prevention of water channeling should be solved through full viscosity. As the microstructure of the base surface of the construction is not smooth, the common waterproof roll material can only stick to the protruding part of the base surface. Although the surface seems to be firmly bonded, the large and small pits on the base surface are all the channels of water channeling. And the polymer liquid rubber waterproof layer by spraying construction can be completely with the base surface. It's full of sticky effect.
