The institute compared the differences between the current national standards and the relevant standards of Japan, South Korea, the European Union, the United States, Australia and other countries and regions, and summarized and compared the specific inspection items and technical indicators of the standards, repeatedly demonstrated and found gaps.

The comparison found that compared with foreign standards, my country's current standards still need to be improved.
On the one hand, although the key performance of the products of leading enterprises in the province has reached the international first-class level, the proportion of high-quality products is still low, and the market share of high-quality products is mainly domestic, and the degree of internationalization is very low.
On the other hand, due to low industry entry barriers, market competition is fierce and product homogeneity is serious.
In order to survive, some manufacturers have launched low-cost and low-quality products, which hinders the improvement of industry quality.

According to reports, the key indicators of the group's standard are higher than the national standard.
First, the requirements for tensile performance have increased.
Under normal conditions at a temperature of 23 ℃, the mechanical tensile strength of the coating is 1.
8 MPa , which is 0.
6 MPa higher than the national standard type I , and the tensile strength retention rate after treatment under various degraded conditions is required to reach more than 90% , Higher than the index requirements of relevant foreign standards.
The second is a substantial increase in the standard level.
Absorbing the advantages of the Japanese and Australian standards, compared with the national standard, it has increased the tensile performance requirements of severe environmental conditions at -20 ℃ and 60 ℃, and the tensile performance requirements of the two degraded conditions of acid treatment and cleaning agent treatment.
The third is the increase in bond strength requirements.
In the national standard, after various deterioration conditions are treated, the bond strengths of Type I, Type II, and Type III are respectively 0.
5 , 0.
7 , 1.
0 , and the group standard is raised to 1.
0MPa .
The fourth is to highlight the advanced nature of standards.
Absorb the strengths of EU and American standards, increase the requirements for crack bridging performance and mildew resistance, and fill the gap in the national standard for this project.

In terms of the adaptability of the standard, the advanced nature of the group standard not only requires polymer cement waterproof coating products, but also suitable for base waterproofing under various severe conditions such as small cracks on the wall, large environmental temperature difference between cold and hot, and mildew on the base.
It can also meet the waterproof requirements of interior decoration such as kitchens, bathrooms, and balconies.
With the implementation of this group standard, it will promote the transformation and upgrading of the waterproof coating industry, and strive to promote the quality of polymer cement waterproof coatings to reach the international advanced level.
