Embodiment Construction

[0015] A kind of manufacturing process of neutral mildew-proof adhesive glue, comprises the following steps:

[0016] Step (1): Add pre-dried nano-calcium carbonate, vulcanized silicone rubber and methyl silicone oil into the stirring tank, start the mixer at a speed of 20 rpm, and stir for not less than 40 minutes;

[0017] Step (2): Raise the temperature to 40°C, add methyl mixed ketoximosilane and vinyl tributylketoximosilane; continue stirring for no less than 40 minutes, then add Γ-aminopropyltriethoxy Silane, N-Β-aminoethyl-Γ-aminopropyltrimethoxysilane and dibutyltin dilaurate, continue to stir for not less than 20 minutes, after stirring evenly, pack and obtain the finished product.

[0018] The structural adhesive includes the following components by weight: 44 parts of vulcanized silicone rubber, 10 parts of dimethyl silicone oil, 40 parts of nano calcium carbonate, 1 part of vinyl tributylketoxime silane, 4 parts of methyl mixed ketoxime silane 0.6 parts of Γ-amino...

Abstract

The invention discloses a manufacturing process of neutral mildew-proof adhesive, which comprises the following steps: adding calcium carbonate, silicone rubber, a mildew preventive and methyl silicone oil into a stirring kettle together, starting a stirrer at a rotating speed of 20 revolutions per minute, and conducting stirring for 40 minutes; adding methyl mixed ketoxime silane and vinyl tributyl ketoxime silane at a temperature of 40 DEG C; conducting stirring for 40 minutes, and then adding gamma-aminopropyltriethoxysilane and N-[3-(trimethoxysilyl)propyl]ethylenediamine and dibutyltin dilaurate, conducting continuous stirring for 20 minutes, conducting uniform stirring, and conducting packaging to obtain a finished product. Compared with the prior art, the preparation method is simple in process and convenient to operate, and the product is mould-proof and corrosion-free; and the adhesive has the characteristics of high strength, high flexibility, high cohesiveness, no need of using a primer when being bonded with most building materials and the like, and also has excellent high- and low-temperature resistance and weather aging resistance, and has excellent bonding strength within 40-150 DEG C after cured.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a manufacturing process of a neutral mildew-proof adhesive glue. Background technique [0002] Glass glue is a material for bonding glass to glass or glass to other substrates. At present, there are many types of glass glue on the market, mainly including acid glass glue, acid structural glue, acid glass slab glue, neutral weather-resistant glue, silicone Stone glue, bathroom anti-mold special glue, etc. [0003] Silicone glue is a part of silicone products. It has strong adhesive force and high tensile strength. It also has the characteristics of weather resistance, shock resistance, moisture resistance, odor resistance and adaptability to large changes in cold and heat. Coupled with its wider applicability, it can realize the bonding between most building materials, so its application value is very large. Acidic silicone glass glue will corrode or fail to bond coppe...
