Problems solved by technology

[0007] The test method of the present invention mixes a certain amount of natural colored sand with a definite particle size into the existing high-strength adhesive, so that the natural colored sand is blocked between the test piece to be tested and the upper clamp for stretching, forming a definite Standardize the thickness of the gap, so that the bonding thickness of the bonding strength is constant, which improves the existing national standards and industry standards in the bonding strength test of building putty and building waterproof coatings caused by irregular bonding thickness. The problem of low success rate and the large fluctuation of experimental results due to the existence of human error improves the success rate of the experiment and achieves the purpose of standardizing the bond thickness in the bond strength test

Embodiment 1

[0055] To test the bonding strength of Kuaitubao flexible waterproof slurry, the method is as follows:

[0056] 1) For the Kuaitubao flexible waterproof slurry to be tested, prepare 10 standard test pieces according to the method of 7.6.2.1-7.6.2.2 in the national standard GB / T23445-2009 of the People's Republic of China and maintain them as required. Good standard test pieces are randomly marked as samples 1-1, 1-2, 1-3, 1-4, 1-5, 1-6, 1-7, 1-8, 1-9, 1-10, 1-11, 1-12, 1-13, 1-14, 1-15;

[0057] 2) Take 20g of NPEL-128 epoxy resin, 10g of BSA-3859 curing agent and 3g of 120-180 purpose natural colored sand respectively, and mix them evenly to obtain a high-strength adhesive;

[0058] 3) Apply the high-strength adhesive obtained by stirring evenly in step 2) quickly and evenly on the standard test piece samples 1-1, 1-2, 1-3, 1-4 and 1- 5 on the coated film surface, according to the method of 7.6.3.1 in the national standard GB / T 23445-2009 of the People's Republic of China, ...

Embodiment 2

[0073] To test the bonding strength of Kuaitubao classic general-purpose waterproof coating, the method is as follows:

[0074] 1) Repeat step 1) of Example 1, the difference is that the Kuaitubao flexible waterproof slurry in step 1) is replaced with Kuaitubao classic general-purpose waterproof coating, and the cured standard test pieces are randomly marked as samples 2- 1, 2-2, 2-3, 2-4, 2-5, 2-6, 2-7, 2-8, 2-9, 2-10, the rest of the conditions remain unchanged;

[0075] 2) Take 20g of NPEL-128 epoxy resin, 10g of BSA-3859 curing agent and 2g of 120-180 purpose natural colored sand respectively, and mix them evenly to obtain a high-strength adhesive;

[0076] 3) Apply the high-strength adhesive obtained by stirring evenly in step 2) quickly and evenly on the standard specimen samples 2-1, 2-2, 2-3, 2-4 and 2- 5 on the coating film surface, measure the viscosity by the method of embodiment 1 step 3).

Embodiment 3

[0086] To test the bond strength of a batch of Lebao Liangjia putty, the method is as follows:

[0087] 1) The batch of Lebao Liangjia putty to be tested is prepared according to the method of 6.12.1-6.12.2.1 in the construction industry standard JG / T 298-2010 of the People's Republic of China, and 10 standard test pieces are prepared and maintained according to the requirements. The cured standard specimens are randomly marked as samples 3-1, 3-2, 3-3, 3-4, 3-5, 3-6, 3-7, 3-8, 3-9, 3-10 , 3-11, 3-12, 3-13, 3-14, 3-15, 3-16, 3-17, 3-18;

[0088] 2) Take 20g of NPEL-128 epoxy resin, 10g of BSA-3859 curing agent and 3g of 120-180 purpose natural colored sand respectively, and mix them evenly to obtain a high-strength adhesive;

[0089] 3) Apply the high-strength adhesive obtained by stirring evenly in step 2) quickly and evenly on the standard test piece samples 3-1, 3-2, 3-3, 3-4, 3- On the coating surface of 5 and 3-6, measure and calculate the bonding strength according to ...

Abstract

The invention discloses a testing method for the binding strength of putty and a waterproof coating for a building. The method comprises the following steps that 1, the putty or waterproof coating test piece with the binding strength to be tested is prepared and maintained according requirements; 2, epoxy resin, a curing agent and spherical particulate matter are mixed according to the mass ratio of 2:1:(0.2-0.4), the mixture is stirred to be uniform, and a high-strength adhesive is obtained; 3, the surface of the test piece which is well maintained in the step 1 is immediately and evenly coated with the high-strength adhesive obtained in the step 2 through uniform stirring, and the binding strength of the test piece is obtained through testing. The method is easy to operate and low in cost, a standard method is slightly improved, and the standard property and accuracy of tests are not affected. The invention further discloses high-strength binding agent for testing of the binding strength of the putty and waterproof coating for the building and application.

Description
