Problems solved by technology

[0006] (1) The hazardous components of leaks are limited, only focus on hazardous substances related to national standards or industry standards, and are limited to target hazardous substances in detection methods;
[0007] (2) The existing method is to obtain the toxic and harmful substance data of the product by means of detection. For the same product, the size of the harmful substance will be determined according to the detection and analysis method, the experimenter, the product source (batch, production process), and the experimental environment. and other factors change;
[0008] (3) Only harmful substances and their content can be informed, and consumers cannot directly obtain the types of health hazards and the magnitude of each hazard in the product

Embodiment 1

[0060] The component evaluation method for health hazards of building material products includes the following steps:

[0061] S1. From the perspective of air contact, according to the "General Rules for Classification of Chemicals and Hazard Publicity", select the types of hazards that pose certain risks to human health from the air exposure route; and according to the grading standards for different health hazards (GB30000.18- 2013~GB 30000.26-2013), generate a summary table of health hazard classification and classification of chemicals;

[0062] S2. According to the health hazard degree and classification and grading summary table of chemicals, and refer to the chemical database and / or chemical safety data sheet (MSDS) by color marking, formulate the health hazard label calibration guidelines of chemicals;

[0063] S3. Obtain the component names and content information of each component of the building material product, including raw materials, chemical reaction products, ...

Embodiment 2

[0069] This specific example discloses the classification category of the chemicals in Example 1.

[0070] The types of hazards that pose risks to human health from the air exposure route are carcinogenicity, reproductive toxicity, germ cell mutagenicity, acute toxicity, serious eye damage / eye irritation, skin corrosion / irritation, respiratory / skin allergy, specific target organ toxicity (single exposure), specific target organ toxicity (repeated exposure).

[0071] In this example, according to GB 13690-2009 "General Rules for Classification and Hazard Communication of Chemicals", the health hazards of chemicals are divided into 10 categories, namely: carcinogenicity, reproductive toxicity, germ cell mutagenicity, acute toxicity, Serious eye damage / eye irritation, skin corrosion / irritation, respiratory / skin sensitization, specific target organ toxicity (single exposure), specific target organ toxicity (repeated exposure), aspiration risk.

[0072] Among them, according to th...

Embodiment 3

[0128] This specific embodiment discloses in step S3 in embodiment 1:

[0129] Starting from the air exposure route, screen the components of building material products that need to be assessed for health hazards, and determine the components that need to be evaluated, including raw materials, chemical reaction products, etc.

Abstract

The invention discloses a component evaluating method for health hazard of a building material product. The method comprises the following steps of S1, gathering hazard kinds which have risks to humanbody health in an air exposure route and grading information for generating a health hazard classification and grading total gathering table of a chemical; S2, according to the health hazard classification and grading total gathering table of the chemical and a chemical database and/or chemical safety technical specification, making a health hazard label marking criteria in a color identificationmanner; S3, acquiring component names of the building material product and content information of each component; and S4, acquiring the health hazard classification and grading information of the component from the chemical database and/or the chemical safety technical specification and/or the health hazard classification and grading calculating rule of a mixture, and performing color identification of the health hazard of the component according to the health hazard label marking criteria of the chemical, and making the health hazard label of the component.

Description

technical field [0001] The invention relates to the technical field of detection or characterization of harmful substances in building material products, in particular to a component evaluation method for health hazards of building material products. Background technique [0002] At present, my country's real estate industry is developing rapidly, and the evaluation of indoor air quality is becoming one of the focus issues that people pay attention to. [0003] Since the 1970s, with the widespread use of organic synthetic materials in interior decoration, it has directly led to a large amount of volatile organic compounds (VOC) in residential buildings, especially newly-built residential buildings, in the interior space of buildings, which has greatly Deteriorated building indoor air quality. In addition, in order to save energy, the airtightness of modern buildings is getting stronger and stronger, which has caused great obstacles to the exchange and circulation of indoor ...
