Description
Technical field
It is specifically a kind of to improve the silicone adhesive aqueous bottom Nian Jie with wood substrate the present invention relates to technical field of aqueous paint
Paint and preparation method.
Background technique
The vulcanization reaction of single-component room-temperature-vulsilicone silicone rubber (RTV-1) is by having an effect and vulcanizing with the moisture content in air
Elastomer-forming.It does not absorb heat when single-component room-temperature-vulsilicone silicone rubber (RTV-1) solidification, not heat release, solidification post-shrinkage ratio is small, to material
Cementability it is good.The formula of many single-component silicon rubber bonding agents is shown to multiple material such as most metals, glass, ceramics
With the automatic adhesive performance on coagulation, but to wooden, plastics isopolarity organic substrate cementability is all very poor.To improve one-component room
The cementability of temperature vulcanizable silicone rubber and different substrate materials, often uses silane coupling agent.So-called silane coupling agent refers to exist in silicone adhesive uncoated
Precoating treatment agent before on substrate, is surface-treated substrate, meanwhile, which has good phase with glue and Nian Jie substrate
Capacitive and binding force, so that enhancing base materials are bonding with silicone adhesive.
Timber is a kind of limited swellable colloid of capillary porous, difficult because wood surface cannot be completely wet by silicon rubber
Therefore to be applied dedicated silane coupling agent with silicone glue sticking by surface treatment, wood surface can be greatly enhanced with silicone adhesive
Cementability, and inorganic agent characteristic determines glue to wood surface adhesive strength.Epoxy resin is a kind of common wood surface
One of material of silane coupling agent.Epoxy resin has many advantages, such as that adhesive force is high, chemical stability is good, cure shrinkage is small, extensive
Applied to fields such as coating, adhesives.Most of common epoxy resin is sticky liquid or solid, is insoluble in water, only molten
In organic solvent.Organic solvent volatilization can cause to seriously endanger to environment and human body.Therefore, exploitation water-soluble epoxy resin is big
Gesture is become.There is also the disadvantages of hard crisp, wear-resisting, heat-resisting and water-fast poor for the aqueous epoxy resins developed at present, through water-soluble
Flexibility, wear-resisting, heat resistance and the water resistance of aqueous epoxy resins etc. after property is nano-silicon dioxide modified are all changed comprehensively
It is kind.The present invention passes through chemic modified method first, be made excellent in stability aqueous epoxy resin emulsion, then by its with through silane
Coupling agent modified silicon sol solution is compound, prepares a kind of environmentally protective high-performance silicone adhesive silane coupling agent, is specially suitable for mentioning
The cementability of high timber and silicone adhesive.
Chinese patent CN1303896A discloses a kind of water epoxy priming coating agent and preparation method, by aqueous epoxy resins；
Acrylic emulsion；Alkyl phenol polyoxyethylene ether；Formaldehyde and water composition；The product is to constructed surface of wall or need to bond cement system
The humidity of product can be used without particular/special requirement, new and old wall.The silane coupling agent odorlessness, it is pollution-free, it is easy for construction, it is at low cost.It should
Although silane coupling agent uses aqueous epoxy resins, accomplish odorlessness, pollution-free, but do not illustrate its whether be used for silicone adhesive with it is wooden
On substrate, also aqueous epoxy resins are not modified with modified silicasol, modified waterborne epoxy in this patent cannot be reached

After being ground on ball mill after being mixed with organic solvent, carbon black, stannous octoate, polyethylene polyamine, triethylamine is added and continues to grind
0.5~1.0 hour, after addition organic solvent diluting is uniform, primary coat was arrived when test isocyanide acid content is 0.1%~0.3%
Agent.The silane coupling agent can effectively improve it is bonding between glazing compound (polyurethane sealant) and windshield substrate, but
The technique the problem is that: (1) during preparing silane coupling agent, need first to prepare performed polymer, then prepare silane coupling agent, and
And prepare and repeatedly to measure isocyano-content during performed polymer and silane coupling agent, process is tedious；(2) due to toxic organic solvents
Application, which not environmentally, is harmful to the human body.
Chinese patent CN103113789A discloses the silane coupling agent and preparation method of a kind of difficult viscous material, by chlorination third
Alkene, organosilicon polymer, acrylic acid esters co-polymer, titanate coupling agent, benzene kind solvent, quinoline and stabilizer mixing, in 77-
Solid content is adjusted at 110 DEG C, silane coupling agent is made, can effectively improve the adhesive strength of the difficult viscous material such as polyethylene, polypropylene, but should
With the presence of quinoline, foul smelling and the big disadvantage of toxicity.
Silicone adhesive silane coupling agent in the prior art mostly be make diluent with organic toxic solvent, although improve silicone adhesive with
The adhesive strength of various materials such as wood substrate and polar organic material, but extremely pollute environment, it is difficult to realize industrialized production.
