Description
Technical Field
The invention relates to the technical field of organic silicon bonding and pouring sealant, and relates to an adhesive addition type organic silicon composition.
Background
The addition curing type organic silicon has the characteristics of high and low temperature resistance, aging resistance, low shrinkage, deep curing, excellent electrical insulation and the like, and is widely applied to the fields of moisture protection, insulation sealing, shock prevention and isolation and the like of electronic components and industrial equipment.
However, the cured product thereof has low molecular polarity and poor adhesion to other materials, and when damaged by external force, it is almost completely peeled from the substrate, which affects the use thereof. Therefore, the industry has been improving the adhesion by improving the formulation, so that the application is more stable and reliable.
The improvement method is mainly to add a plurality of polar group-containing organic silicon tackifiers in the formula so as to improve the bonding performance. However, the effect of thickening is very limited by simply adding different types of low-molecular coupling agents to the formulation in a physical mixture. The preferred method is to add a self-synthesized adhesion promoter with a specific molecular structure to the formulation. The molecular structure of the tackifier comprises double bonds or hydrosilyl on one hand, and can participate in addition reaction to form chemical bonds with the main chain of the silicone rubber molecule; on the other hand, one or more of polar groups such as epoxy group, amino group, (meth) acryloxy group, isocyanate group, borate group, alkoxy group and the like can form chemical bonds or hydrogen bonds with the base material directly or after reaction. Thus, firm chemical crosslinking is formed between the cured silicone rubber main chain and the base material through the tackifier, so that the adhesion and the sealing performance are greatly improved. Meanwhile, the tackifier is still an organic silicon material, has good compatibility with a formula system, is stable to store, and does not bring other adverse effects.
For a long time, a plurality of tackifiers are synthesized by the technicians in the field and added into the formula of addition type organic silica gel or encapsulation materials so as to improve the adhesion and the sealing property of materials such as metal, plastic and the like and obtain certain effect. Such as: CN102898972A and CN102994004A are prepared by heating and non-aqueous condensing monomers such as hydroxyl-containing acrylate or hydroxyl-containing allyl ether and the like and alkoxy silane coupling agents such as epoxy group, acryloxy group and the like under the catalysis of titanate, and purifying by dealcoholization under reduced pressure to prepare the tackifier; CN108239284A is prepared by performing hydrolytic condensation on vinyl alkoxy silane and coupling agents such as epoxy group and acryloxy alkoxy silane in a solvent/water mixture under the catalysis of acid, and then performing purification steps such as neutralization, liquid separation, water washing, drying, reduced pressure reduction and low pressure reduction to prepare a tackifier; CN107674608A and CN111484620A are prepared by reacting dihydric alcohol acrylate containing carbon-carbon double bond, vinyl coupling agent and/or allyl glycidyl ether with hydrogen-containing silicone oil or D4 H Performing catalytic addition by a platinum complex, adsorbing to remove platinum, and performing reduced pressure reduction and purification to obtain the tackifier; CN104531003A is to perform ester exchange between boric acid ester and active hydroxyl compound containing unsaturated bond, remove low and purify to obtain the tackifier containing boron and unsaturated bond.
The molecular structure of the tackifier contains one or more polar groups except alkoxy, such as epoxy group, (methyl) acryloxy group and the like, besides unsaturated bonds or silicon-hydrogen bonds which can participate in main chain addition reaction, and plays a certain role in improving the adhesiveness and the sealing property of the addition type silicone rubber on the surfaces of different metals and plastics. However, the synthesis process of the tackifiers is still complex, waste water and waste gas are generated, and certain environmental protection and safety problems exist.
Therefore, the development of the adhesive addition type organic silicon composition which has simple synthesis process, low cost and environment-friendly and safe preparation process is of great practical significance.

Examples 2 to 4 and comparative examples 1 to 2

TABLE 1
The adhesion tests were carried out on the products obtained in the above examples and comparative examples, as follows:
cutting the material used in the test into a test piece of 100mm 25mm 2mm, uniformly mixing a first component and a second component according to the mass ratio of =1:
and (3) optimization: failure interfaces were all cohesive failure
