Embodiment Construction

[0013] A high-temperature-resistant antibacterial foam plastic, which contains a matrix, a foaming agent, a flame retardant, an antioxidant, a toughening agent, a dispersant, an antibacterial agent and other additives, and the content of each component is: 82-90% of the matrix , foaming agent 2~5%, flame retardant 0.7~1.1%, antioxidant 0.1~0.5%, toughening agent 3~6%, dispersant 0.8~1.2%, antibacterial agent 8~10%, other additives 1~2%.

[0014] The matrix is ​​one of polystyrene, polyurethane and phenolic resin.

[0015] The foaming agent is one of sodium lauryl sulfate and fatty alcohol polyoxyethylene ether sodium sulfate.

[0016] The flame retardant is selected from one of magnesium hydroxide and aluminum hydroxide among the inorganic flame retardants.

[0017] The antioxidant is 2,6-tertiary butyl-4-methylphenol, bis(3,5-tertiary butyl-4-hydroxyphenyl)sulfide, tetrakis[β-(3,5- At least one of tertiary butyl-4-hydroxyphenyl) propionate] pentaerythritol esters.

Abstract

The invention belongs to the technical field of antibacterial foamed plastic and discloses high-temperature-resistant antibacterial foamed plastic which is contains, by content, 82-90% of matrix, 2-5% of foaming agent, 0.7-1.1% of fire retardant, 0.1-0.5% of antioxidant, 3-6% of flexibilizer, 0.8-1.2% of dispersant, 8-10% of antibacterial agent and 1-2% of other auxiliaries. Raw materials of components are easy to get and low in price, tourmaline can release anions which can adjust ion balance of human bodies, relax body and mind, activate cells, improve self-healing rate, inhibit oxidation of bodies, eradicate odors and the like; silver ions have functions of radiation protection, sterilization and disinfection; and nano silicon dioxide and nano titanium dioxide can emit infrared rays to function in healthcare.

Description

technical field [0001] The invention relates to a high-temperature resistant antibacterial foam plastic, which belongs to the technical field of antibacterial plastic. Background technique [0002] Foam insulation is widely used in buildings, whether on walls or floors, because of its low thermal conductivity, it can keep the temperature inside the building warm in winter and cool in summer. With the wide application of plastic products, people have higher and higher performance requirements for plastic products. Negative ions are a kind of negatively charged gas ions in the air. Negative ions can not only promote the synthesis and storage of vitamins in the human body, strengthen and activate the physiological activities of the human body, but also have a very important impact on the activities of the human body and other life, so it is called "air". Vitamins". Negative ions can gradually reduce acidity, oxidation, active oxygen, lactic acid and other factors that damage ...
