The present application relates to the low temperature curing high-strength benzoxazine type silicone adhesive formula and use method, the formula includes the benzoxazine group containing organic silicon compound and organic alkali compound, the mass ratio of benzoxazine group containing organic silicon compound, organic alkali compound is 100:0.1-20.The adhesive of the present application is based on the cooperation between the benzoxazine group containing organic silicon compound and the basic catalyst, can be cured at low temperature, realize the higher strength bonding.The benzoxazine type silicone adhesive formula provided by the present application can be directly used as adhesive, and the bonding strength is high;It can also be used as a basic formula, used as an adhesive after adding other fillers, to meet the different needs of various special occasions.

This utility model discloses an adjustable coating width roller coating machine, including a mounting frame. A connecting plate is fixedly connected to one side of the mounting frame. Two sets of mounting plates are fixedly connected to the upper side of the mounting frame and the connecting plate. A power shaft is rotatably connected between the mounting plates. A motor is fixedly connected to the outer side of one of the mounting plates. The power end of the motor is fixedly connected to the power shaft. A fixed roller is fixedly connected to the outer side of one side of the power shaft. Several sets of connecting rollers are slidably connected to the outer side of the power shaft. An insertion groove is opened on one side of the fixed roller and the connecting roller. Four sets of follower grooves communicating with the insertion groove are opened on one side of the fixed roller and the connecting roller. An insertion shaft that matches the insertion groove is fixedly connected to the other side of the connecting roller. Four sets of follower blocks that match the follower groove are fixedly connected to the other side of the insertion shaft. By changing the width of the coating roller, the amount of paint used can be changed according to the width of the object being coated, thereby reducing paint waste.

This invention discloses an organofluorosilicone emulsion deepening agent, which is made from the following raw materials in parts by weight: 3-9 parts of hexamethylcyclotrisiloxane, 2-4 parts of trifluoropropylmethylcyclotrisiloxane, 1-3 parts of hexamethyldisiloxane, 3-9 parts of vinyldisiloxane, 1-3 parts of emulsifier, 0.1-0.6 parts of catalyst, and 2-6 parts of acrylate monomer. The organofluorosilicone monomer is prepared by ring-opening reaction of hexamethylcyclotrisiloxane, trifluoropropylmethylcyclotrisiloxane, and hexamethyldisiloxane under the action of trifluoromethanesulfonic acid catalyst. Then, the emulsifier is used to emulsify the monomer to obtain organofluorosilicone emulsion I. This invention has a simple preparation method, can reduce dye affinity, and inhibit dye migration. Furthermore, by changing the amount of emulsifier, the particle size of the emulsion can be adjusted, and emulsions of different particle sizes can be mixed together to form a film with different roughness, thus achieving a deepening effect.
