Introduction
In the design adhesive joints, it is necessary to know the exact value of the mechanical properties of the adhesive, it is possible to calculate the stress distribution in the joint loading and correct
Set Adhesive damage allowable value. Use adhesive joints in the form of a sample to test the performance of the above-mentioned method is not ideal. Because the standard sample
The layer thickness on the size of the strain and the thickness value is generally small (typically < 1mm), so the value of the test strain not allowed. Moreover, a plastic
Joints destruction of the sample is usually due to stress caused by the multiple, the main factors are. the geometry of the glued joints, adherend
Performance and size and geometry of the fillet. Although the destruction of data samples can provide information for the design of adhesive joints, but also need eligible
When too many single state of stress (such as shear and uniaxial tensile) deformation and destruction of data.
Use the appropriate sample size of the body, through the application of engineering standards is a measure of the mechanical properties under different loads and environmental conditions,
Such testing more accurate and low cost.
By sample preparation methods specified below can be obtained joint structure and properties of the sample and the corresponding bonding. Sticky adhesive and the adherend
Received performance-related information needed by the relevant test adhesive joints obtained.

Part 1. two component systems
1 Scope
This section GB/T 22376 describes the preparation of bulk adhesive sample.
Preparation method described in this section applies to a two-component adhesive, such as epoxy, polyurethane, acrylate.
This method does not apply to prepared adhesive bulk sample gas released volatile solvent escape or cured. While not applicable
Those in single-component adhesives to be used in a bonding surface of the initiator. In addition, this method is not suitable for operating time is very short glue
Sticky agent, because there is not enough time to mix rubber, plastic injection and mold.

3 Definitions
The purposes of this section, according to GB/T 2035 stipulates that references the following terms.
3.1
It refers to the preparation of adhesives or resins after to maintain its performance in the time available.
4 Die
4.1 Overview
The mold should comprise two plates separated by restrictions block, U-frame or continuous box (see Figure 1) between the two plates.
a) limit block b) U-shaped frame c) continuous box
Example 1 Model
4.2 Tablet
Preparation of 5mm thick metal plate using at least said two plates. This facilitates heat transfer adhesive curing process, but also to avoid sample preparation
