Description

A kind of silicone oil-free conductive strip and manufacturing process

technical field

The invention relates to a silicone oil-free conductive strip and a manufacturing process, and belongs to the technical field of silicone conductive strips.

Background technique

Traditional conductive strips contain silicone oil and are consumables. Conductive strips containing silicone oil will accumulate silicone oil, which requires operators to perform manual wiping operations; especially after 24 hours of use, the accumulation of silicone oil will become more and more. The more serious it is, it is difficult to wipe clean. The silicone oil-containing oil should be wiped with acetone every two hours, which can only be used for one day; frequent wiping greatly reduces the production efficiency, and frequent replacement will lead to an increase in production costs.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide a silicone oil-free conductive strip and a manufacturing process, thereby overcoming the deficiencies in the prior art.

The technical scheme of the present invention is that it comprises a silica gel foam layer and a conductive layer, the silica gel foam layer is filled between the conductive layers, and the conductive layer is wrapped in the silica gel foam layer;

The silicone foam layer includes two side walls and a filling section arranged between the N conductive layers;

The conductive layers are arranged on both sides of the filling section, and both ends are sandwiched and wrapped by the side walls.

The present invention comprises the following desiliconization steps:

Step 1, bake the conductive strip including the silicone foam layer and the conductive layer in a high temperature environment of 60°C for 1 hour;

Step 2, soak in kerosene for 12 hours;

Step 3, soak in alcohol for 2 hours;

Step 4, drying for 1 hour, and then drying at 40° C. for 20 minutes to generate a finished product.

The silicone foam layer does not contain silicone oil.

The beneficial effect of the invention is that there is no oil accumulation phenomenon of silicone oil, which reduces the production cost, the preparation process of the method provided by the invention is simple and easy to realize, and the production efficiency is improved; the conductive strip containing silicone oil should be wiped with acetone every two hours, only It can be used for one day, and the conductive strip after removing the silicone oil does not need to be wiped, and can be used for 5 to 7 days, which prolongs the service life of the conductive strip.

Detailed ways

The preferred embodiments of the present invention are further described below in conjunction with accompanying drawings 1 to 2, including a silicone foam layer 1 and a conductive layer 2, the silicone foam layer 1 is filled between the conductive layers 2, and the conductive layer 2 is wrapped in the silicone foam layer 1;

The silicone foam layer 1 includes two side walls 11 and a filling section 12 arranged between the N conductive layers 2;

The conductive layers 2 are arranged on both sides of the filling section 12 , and both ends are sandwiched and wrapped by the side walls 11 .

The present invention comprises the following desiliconization steps:

Step 1, baking the conductive strip including the silicone foam layer 1 and the conductive layer 2 in a high temperature environment of 60° C. for 1 hour;

Step 2, soak in kerosene for 12 hours;

Step 3, soak in alcohol for 2 hours;

Step 4, drying for 1 hour, and then drying at 40° C. for 20 minutes to generate a finished product.

The silicone foam layer 1 does not contain silicone oil, thereby prolonging the life. The conductive strips containing silicone oil should be wiped with acetone every two hours and can only be used for one day;
