Problems solved by technology

[0002] During the assembly process of engine components, bonding and sealing treatment is often required on the joint surfaces. Usually, some existing commercially available liquid sealants are used, but some of them have poor oil resistance, and some are inconvenient to use in the component assembly environment. , difficult to remove; some bonding and sealing effects are not good, and some have great pollution to the human body and the environment during use, which limits the design and material selection of some components

Embodiment 1

[0018] First weigh 40g of shellac flakes with a balance, crush them and put them into a clean container, add 52g of absolute ethanol, cover the container tightly and leave it for 24 hours. After it is completely dissolved, add 2g of castor oil and stir evenly, then add 5g of colloidal graphite powder and stir Evenly, then add 1g of aluminum powder slurry and stir thoroughly (first dilute the aluminum powder slurry with a small amount of absolute ethanol) to form a uniform mixed glue.

Embodiment 2

[0020] First weigh 45g of shellac flakes with a balance, crush them and put them into a clean container, add 52g of absolute ethanol, cover the container tightly and leave it for 24 hours, after it is completely dissolved, add 3g of castor oil and stir evenly, then add 6g of colloidal graphite powder and stir Evenly, then add 1.5g of aluminum powder slurry and stir thoroughly (first dilute the aluminum powder slurry with a small amount of absolute ethanol) to form a uniform mixed glue.

Embodiment 3

[0022] First weigh 40g of shellac flakes with a balance, crush them and put them into a clean container, add 50g of absolute ethanol, cover the container tightly and leave it for 24 hours, after it is completely dissolved, add 3g of castor oil and stir evenly, then add 5g of colloidal graphite powder and stir Evenly, then add 2g of aluminum powder slurry and stir thoroughly (first dilute the aluminum powder slurry with a small amount of absolute ethanol) to form a uniform mixed glue.

Abstract

The invention aims to provide a dry sealing adhesive and a preparation method thereof. The dry sealing adhesive comprises the components of, by weight, 40-52 parts of anhydrous ethanol, 40-48 parts of shellac, 4-8 parts of colloidal graphite powder, 2-4 parts of castor oil and 1-2 parts of aluminum paste. The liquid sealing adhesive can be used for faying surfaces of components, plays a bonding and sealing effect, and can be used for sealing component systems of gas, lubricating oil and the like. When being in use, the drysealing adhesive is applied on the mutually connecting parts of the components. The dry sealing adhesive is convenient for use; and the adhesive layer is easy to remove. The dry sealing adhesive has little pollution to both human body and the environment, and is simple and convenient in construction process, so that quality and production efficiency of the produce can be increased. The dry sealing adhesive provides an excellent material for the design of product components.

Description

technical field [0001] The invention relates to a dry sealing glue, and in particular provides a viscous dry sealing glue and a preparation method thereof. Background technique [0002] During the assembly process of engine components, bonding and sealing treatment is often required on the joint surfaces. Usually, some existing commercially available liquid sealants are used, but some of them have poor oil resistance, and some are inconvenient to use in the component assembly environment. , It is difficult to remove; some bonding and sealing effects are not good, and some have great pollution to the human body and the environment during use, which limits the design and material selection of certain components. Contents of the invention [0003] The purpose of the present invention is to provide a dry sealing glue and its preparation method. The liquid sealing glue can be widely used on the joint surface of parts and components to play the role of bonding and sealing, and c...
