Foreword

GB/T 22376 "Adhesive bulk sample preparation method" is divided into two parts.

--- Part 1. Two-component system;

--- Part 2. Hot curing one-component system.

This section GB/T Part 122 376, equivalent using ISO 15166-1:1998 "body sample preparation Adhesive Part 1. The two-component system "(in English).

This section is equivalent translation ISO 15166-1:1998, part of the normative references replaced by the national standards with international standards, the reference standard Associate content with international standards there is no difference.

For ease of use, this standard to the following editorial changes.

a) "this International Standard" be replaced by "this standard";

b) Remove the preface to the international standards.

This part is proposed by the China Petroleum and Chemical Industry Association.

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 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.
