The average annual growth rate of major waterproof materials will remain increase at the rate of over 10 %, and the output of major waterproof materials is expected to reach 1,600 million square meters by 2015 to meet the ballooning waterproof market demand.
In 2012, production of Chinese waterproof building materials reached 1,356 million square meters, rose by 12.70% compared with 2011, in which new waterproof materials accounted for 90% , and the share will continuously increases.
A fast detection method for such materials should be set up as soon as possible

Experimental Materials.
The PUs thermal stability for a series of MDI based materials has been also investigated.
Shown in Fig. 2 are example TGA curves for three polyether PPG materials with different HS.
But the aging process of the materials is more complicated.

In order to lighten road dilapidation efficiently, basecourse material must have better anti-freezing performance.
However, Lime-soil and Lime-Flyash-Soil are popular basecourse materials with good anti-freezing property, and they are suitable for cold climate in northeast, so, for the index of freezing, compound consolidated soil can satisfy the application in seasonal freezing area, Conclusions From the study, the following conclusions can be got
(3) The antifreeze performance of compound consolidated soil base materials is significantly better than the limestone soil and lime-flyash composite consolidated soil road base materials under indoor freeze-thaw cycle test, so it is very suitable for the areas of seasonal frozen .

However, its adhesion mechanism is different when the adhesive is bonding with polyester film, paper, fabric, metal and other materials.
Isocyanates are one of the most important raw materials, and they are divided into aliphatic isocyanates and aromatic isocyanates.
So there is a tendency to use aliphatic isocyanates as raw materials.
It also has stronger adhesion strength to polar materials, higher cohesive energy strength and good thermal oxidation stability.
