Description

Instant sealing silicone sealant and preparation method thereof
Technical Field
The invention belongs to the technical field of high polymer materials and preparation thereof, and particularly relates to an instant sealing silicone sealant and a preparation method thereof.
Background
The single-component silicone sealant is a pasty high polymer material and can be cured into a tough rubber solid when contacting with moisture in the air. The silicone adhesive has the characteristics of strong bonding force, good sealing performance, weather resistance, vibration resistance, moisture resistance, odor resistance and large adaptability to cold and heat changes. In addition, the wide applicability can realize the sealing of most engineering mechanical parts and the bonding between building material products, so the application value is very high
The silicone sealant does not flow under its own weight and can be used over a seam in a roof or sidewall without sagging, slumping or running off. It is mainly used for bonding and sealing of dry and clean metal and glass, most of grease-free wood, silicone resin, vulcanized silicone rubber, ceramics, natural and synthetic fibers, and many painted plastic surfaces. The high-quality silicone adhesive can not be extruded and the physical properties can not be changed when used at the temperature below zero ℃. The fully cured silicone glass adhesive can maintain the strength continuously and effectively when used at 210 ℃.
The silicone adhesive is required to have initial strength and bear certain sealing pressure after being coated for about 30 minutes in the using process, particularly in the flow line operation process in some mechanical fields. Generally, silica gel cannot be rapidly cured in a short time after being coated with glue and has initial strength, and a mechanical assembly line needs to be continuously stopped and intermitted to wait for the curing process of the glue when in use. Therefore, the production continuity is seriously influenced, and the production assembly efficiency of mechanical parts is reduced.
Disclosure of Invention
In order to overcome the defects of the prior art, the invention provides the silicone adhesive which can be quickly cured and can be immediately sealed and the preparation method thereof.
An instant sealing silicone adhesive is composed of the following components in percentage by weight: 28-32% of hydroxyl-terminated polydimethylsiloxane (viscosity 20000cp), 20-24% of hydroxyl-terminated polydimethylsiloxane (viscosity 3000cp), 35-40% of nano calcium carbonate, 4.0-6.0% of methyl tributyrinoxime silane, 1.0-2.0% of vinyl tributyrinoxime silane, 3.0-5.0% of fumed silica, 0.03-0.06% of hexamethyldisilazane, 0.03-0.06% of dibutyltin dilaurate and 0.03-0.06% of N- (beta-aminoethyl) -gamma-aminopropyltrimethoxysilane.
Preferably, the instant sealing silicone adhesive consists of the following components in percentage by weight: 29.5% hydroxy-terminated polydimethylsiloxane (20000 cp viscosity), 21% hydroxy-terminated polydimethylsiloxane (3000cp viscosity), 38.5% nano calcium carbonate, 5.4% methyltributanonoximosilane, 1.0% vinyltributonoximosilane, 4.45% fumed silica, 0.05% hexamethyldisilazane, 0.05% dibutyltin dilaurate and 0.05% N- (beta-aminoethyl) -gamma-aminopropyltrimethoxysilane.

The structure has excellent high and low temperature resistance, and can be used for a long time at-60 to +250 ℃. Excellent dielectric property, hydrophobic, moisture-proof, ageing-resistant and electric insulating property.
The nano calcium carbonate is a novel superfine solid powder material, and the granularity of the nano calcium carbonate is between 0.01 and 0.1 mu m. Because of the superfine nano calcium carbonate particles, the crystal structure and the surface electronic structure of the nano calcium carbonate particles are changed, and the quantum size effect, the small size effect, the surface effect and the macroscopic quantum effect which are not possessed by the common calcium carbonate are generated. The nano calcium carbonate is applied to the sealant material, has good affinity with a rubber material, can accelerate the crosslinking reaction of the rubber, greatly improves the thixotropy of a system, enhances the dimensional stability, improves the mechanical property of the rubber, and achieves the dual functions of filling and reinforcing. Meanwhile, the surface of the sizing material can be bright and fine.
Methyl tributyrinoxime silane and vinyl tributyrinoxime silane belong to ketoxime group coupling agents. When used as a crosslinking agent, they may be used in different mildness degrees in the reaction. The cross-linking reaction of the cross-linking agent is ensured to occur in time and the cross-linking agent is ensured to be effective and durable in use by matching.
Dibutyltin dilaurate has excellent light stability and transparency, and can be used as stabilizer for polyvinyl chloride, mainly for soft and semi-soft polyvinyl chloride products, such as transparent film, pipe, artificial leather, etc., and can be used as polyurethane catalyst.
The preparation method of the instant sealing silicone adhesive comprises the following steps of based on the total weight percentage of the instant sealing silicone adhesive to be prepared:
