国际标准化组织 23169-2020 “油漆和清漆内墙涂料质量评估的现场试验方法”

介绍
A typical interior wall coating system (见图 1) consists of a thick filler, a coating primer, and two finishes. 因此, the final quality of the interior wall depends on the entire paint system from the filler to the primer to the top coat. 此外, the quality of the coating conditions, such as film thickness and paint water dilution rate, has a significant impact on the final wall coating system.

数字 1 — Typical interior wall coating system

1 基质 (wall)
2 包装
3 Primer (1 coat)
4 Top coat (2 coats)
There is no standardized field test method in the market to check the performance of the entire system. 现在, so-called “field testing methods” rely on visual testing, nail scrubbing and touch. These methods are subjective, as the results may vary from person to person, even for the same wall coating system, and the results are not repeatable. 所以, this document provides standardized test methods for on-site wall paint evaluation. Using these standardized test methods can help distinguish between high quality and low quality interior wall paints.

1 范围
This document specifies two field test methods (field cleanliness [stain removal] and field resistance to wet scrubbing) for assessing the quality of interior wall coatings.

These tests are applicable to white coatings and light coatings where the tri stimulus value Y10 is greater than 25 measured on samples consisting of coatings coated on a black substrate.

The cleanability test can differentiate paint quality into 18% pigment volume concentration (PVC) and critical pigment volume concentration (CPVC). Field test methods for wet scrubbing resistance can differentiate coating quality when PVC is almost equal to or above CPVC.

3 术语和定义
就本文件而言, ISO 中给出的术语和定义 4618 并且以下文章适用.

3.1 Paint to water dilution ratio

The ratio of water to paint, expressed as a percentage of mass

3.2 Light Color Coating

Coatings with a tristimulus value of Y10 greater than 25 were measured by spectrophotometer on a sample consisting of coatings coated on a black substrate

笔记 1: The tests shall comply with ISO 6504-3.

3.3 清洁度

The dry coating film is able to withstand the penetration of the dirt agent and is released from it through the cleaning process without removing more than the specified film thickness

[来源: 国际标准化组织 11998:2006, 3.1]

3.4 Site wet scrubbing resistance

Ability of the dry film to withstand an average loss of less than the specified oil film thickness within a specified area when exposed to a specified wet scrub cycle (3.5)

笔记 1: In ISO 11998, resistance to wet scrubbing is based on laboratory tests of 200 wet scrubbing cycles.
