Introduction
Building sealing materials are a type of functional building materials that can withstand joint displacement to achieve airtight and watertight purposes and are embedded in building joints.
It is of great significance to improve the sealing, energy saving, waterproof, sound insulation, dustproof and other functions of buildings. In response to the country's priority development of new defense
The planning outline of water sealing materials, standardize product quality, and guide the healthy and orderly development of the product market. From the 1980s to the present, my country has gradually
A relatively complete standard system for building sealing materials has been established. GB/T 13477 is an important component of the standard system for building sealing materials.
Based on the international standard system documents corresponding to ISO /TC59/SC8, 23 parts have been released and implemented.
GB/T 13477 is a basic and general test method standard to guide the performance testing of building sealant products in my country.
Provide technical support for product standard setters, producers, and developers. GB/T 13477 is divided into 5 categories, classification and some structures that have been published and implemented
into the following.
---Test conditions (Part 1), specifying conditions such as test substrates;
---Construction performance category (Part 3~Part 6, Part 22), specifying the extrudability, pot life, surface dry time, flow of the product
Determination methods of properties, curing properties, etc.;
---Physical/mechanical properties (Part 2, Part 7, Part 16, Part 17, Part 19), specifying the density of the product,
Determination methods for low temperature flexibility, compression properties, elastic recovery rate, mass and volume changes, etc.;
---Adhesive properties with the base material (Part 8~Part 14, Part 18), specifying the tensile adhesion and constant elongation adhesion of the product
Determining methods of adhesion, adhesion after water immersion, adhesion after tension-compression, peel adhesion, adhesion after high/low temperature treatment, etc.;
---Durability/Aesthetics (Part 15, Part 20, Part 21, Part 23), specifying the artificial weathering resistance of the product
Determination methods such as property, pollution property, dust accumulating property, appearance change, etc.
This document is the 22nd part of GB/T 13477, which belongs to the category of construction performance, and specifies the determination method for the curing properties of sealants.
It provides a reliable basis for selecting and evaluating the curing characteristics of sealants, which is conducive to eliminating technical barriers to trade and better promoting trade, communication and technology.

3 Terms and Definitions
The terms and definitions defined in GB/T 14682 apply to this document.
4 principles
Place the sealant to be tested in a curing environment to prepare a test piece, and record the time when the curing depth reaches 2.0mm with a single-component sealant.
During the period, the multi-component sealant records the time when its hardness reaches 33% of the final hardness, which characterizes the curing characteristics of the sealant.
