[0004] CN10129855B discloses a kind of nano anti-mildew neutral silicone sealant, its effective anti-mold agent component is nano-silver particles, which has the disadvantages of high cost, easy discoloration, and weak inhibitory effect on mold
[0006] CN102485823A discloses an anti-mildew silicone sealant. The anti-mold agent used in this invention patent is 2n acylisothiazolinone and benzisothiazolinone (BIT). After searching a large amount of data, it is found that its component 2n acylisothiazolinone The linone description is inaccurate
It is said that the anti-mold sealant of the invention has excellent anti-mold effect, but the pure organic anti-mold agent often migrates to the surface of the material too quickly, which is easy to cause loss, thus affecting the anti-mold durability of the material
[0007] CN102604586A discloses a production method of anti-mold silicone sealant for insulating glass. No anti-mold ingredients are added in the production process. It is said that it will never become moldy in wet places, but the actual operation is not necessarily the case. The silicon contained in its componen

Abstract

The invention relates to a long-acting antibacterial and mildew-proof silicone adhesive and a preparation method thereof. The preparation method comprises the steps: grinding an efficient and environment-friendly organic sterilizing and mildew-proof agent and an inorganic zinc loaded zeolite antibacterial agent with a porous structure at high speed in high-speed grinding equipment and thus organically combining the organic sterilizing and mildew-proof agent and the inorganic zinc loaded zeolite antibacterial agent by using a coupling agent on the basis of comprehensively researching and analyzing the characteristics of all antibacterial and mildew-proof agent systems to obtain a novel composite antibacterial and mildew-proof agent; then, adding the obtained composite antibacterial and mildew-proof agent into a silicone adhesive material by using the traditional silicone adhesive production equipment and a conventional adhesive preparation process to finish the preparation of the long-acting antibacterial and mildew-proof silicone adhesive. The antibacterial and mildew-proof silicone adhesive provided by the invention is low in raw material cost, simple in production process, free of three wastes and capable of meeting the requirement for environment friendliness. The long-acting antibacterial and mildew-proof silicone adhesive prepared by the invention is efficient and durable in antibacterial and mildew-proof performances and capable of meeting the technical requirement for use in fields such as buildings, electronic appliances, automobiles, boats and the like.

Description

technical field [0001] The invention relates to the field of sealants. More specifically, the present invention relates to a silicone glue with long-acting antibacterial and antimildew functions, and also relates to a preparation method of the antibacterial and antimildew silicone glue. Background technique [0002] One-component room temperature vulcanization (RTV-1) silicone glue is widely used in sanitary ware, countertops, walls, and furniture in kitchens, bathrooms, and toilets because of its excellent aging resistance, good elasticity, and outstanding waterproof performance. Waterproof sealing of indirect joints, and the amount is increasing. However, because these places are relatively humid all year round, silicone rubber is easily attacked by bacteria, molds and other microorganisms, resulting in moldy, discolored, falling off, and loss of sealing and waterproof functions. These harmful bacteria will also infect various diseases if they come into contact with the h...
