20℃ Phase Change Microcapsules Can Be Added To Building Materials Such As Interior Wall Paints


Composition and structure:

• It usually consists of a capsule wall and a capsule core.
• The cyst wall is generally a polymer material with good chemical stability and mechanical strength, which can effectively wrap and protect the cyst core substance. The capsule core is a phase change material that occurs when the temperature reaches 20°C.
• At temperatures below 20°C, the core is in a relatively stable physical state (e.g., solid), while when the temperature rises to 20°C and above, the core transitions to another state (e.g., liquid).

Performance characteristics:
1.Temperature response characteristics

• When the ambient temperature is close to or reaches 20°C, the phase change material of the capsule core begins to absorb heat and undergoes a phase transformation, which can absorb a large amount of heat, so as to effectively maintain the relative stability of the surrounding ambient temperature at about 20°C.
• For example, in some storage environments with specific temperature requirements, when the temperature tends to rise, the phase change microcapsules prevent the temperature from rising too quickly by absorbing heat.
• When the temperature drops, the core will change from liquid state to solid state, releasing the previously stored heat, which plays a certain role in heat preservation and helps to maintain the ambient temperature from plummeting.

2.Good stability

• The existence of the cyst wall makes the cyst core material relatively isolated from the external environment, which reduces the possibility of chemical reaction between the cyst core and the outside world, and ensures the stability of the microcapsule during storage and use.
• Even after multiple phase change cycles, the microcapsules are able to maintain good performance.

3.The size is small

• Microcapsules generally have a micron size, which allows them to disperse well in a variety of substrate materials, such as coatings, plastics, etc., without significantly adversely affecting the performance and appearance of the matrix.
• At the same time, the small size is also conducive to increasing the contact area between the microcapsule and the surrounding environment and improving the heat exchange efficiency.

4.Adjustability

• By selecting different capsule wall and core materials and adjusting the preparation process parameters, the phase change temperature and latent heat of phase change of microcapsules can be adjusted to meet the needs of different application scenarios.

Fields of application:
1.Cold chain transportation

• When transporting temperature-sensitive goods such as fresh food and medicines, 20°C phase change microcapsules can be used to make thermal insulation packaging materials. When the ambient temperature rises close to 20°C, the microcapsules absorb heat and prevent the goods from deteriorating.
• When the temperature drops, the microcapsules release heat to maintain the relative stability of the ambient temperature of the goods and ensure the quality and safety of the goods.

2.Intelligent temperature control textiles

• Add it to fiber or fabric to make garments with temperature regulation. When the temperature around the human body is close to 20°C, the microcapsules are able to absorb or release heat according to the temperature change, making the human body feel comfortable.
• It is especially suitable for some work clothes in special working environments that require temperature regulation, such as outdoor work clothes.

3.Electronic equipment protection

• Some electronic components are more sensitive to temperature, and their surface is coated with a heat dissipation material containing 20°C phase change microcapsules, when the electronic components work and heat up to close to 20°C, the microcapsules absorb heat, prevent the components from being damaged due to overheating, and improve the stability and service life of electronic equipment.

4.Indoor temperature regulation

• It can be added to building materials such as interior wall paints, etc.
• When the indoor temperature is close to 20°C, the microcapsules absorb or release heat through phase change, which plays a role in regulating the indoor temperature, reducing the frequency of use of air conditioning and other equipment, and achieving the purpose of energy saving.

First aid measures:

• In case of eye contact, rinse with plenty of water. Skin-to-skin contact: Remove contaminated clothing and shoes. Rinse with soap and water for 15 minutes. Accidental ingestion: Rinse your mouth and send to the hospital as soon as possible.

Packaging and storage:
1. Packing method

• 25 kg/bag

2. Storage method

• Dry, cool and ventilated place without sharp objects.
