Abstract

This invention discloses a production method for super large silica gel rollers including: matching sizing materials, smelting the sizing material, processing to the rolling core, extruding and winding it with gel, sulfurizing,lathing and grinding, in which, the product is processed by sizing materials of high intensity, anti-avulsion and anti-high temperature and applies special bond to brush on a roll core especially processed to agglutinate the sizing and the core tightly, which greatly prolongs the life time of rollers.

Description

The production method of superlarge silica gel roller

One, technical field

The present invention relates to the production process of a kind of production method of silica gel roller, particularly superlarge silica gel roller.

Two, background technology

Superlarge silica gel roller is mainly used on the BOPP production line, and the BOPP production line is an automatic assembly line of producing the 0.03mm thickness thin film.At present, the production of this product mainly concentrates on countries such as U.S., moral, day abroad, and technology, technology all maintain the leading position.And the BOPP film that China needs mainly solves by import.The twentieth century end, China is successively from 120 BOPP production lines of external introduction, and large-scale silica gel roller (4-6 rice) has only minority producer such as Shanghai to produce, and superlarge silica gel roller (length is more than 8 meters) does not also have a family can produce, domestic so far still is blank.

Three, summary of the invention

The production method that the purpose of this invention is to provide a kind of superlarge silica gel roller prolongs rubber roll service life, and makes the superlarge silica gel roller production domesticization.

Technical scheme of the present invention is:

A, rubber mass compounding, component content such as table 1:

Table 1

The raw material title	％
The raw material title	％	Methyl vinyl silicone rubber	51.8-66.7
The white carbon black of high reinforcement	20.0-31.2	Methyl vinyl silicone rubber	51.8-66.7
The white carbon black of high reinforcement	20.0-31.2	Di-iron trioxide	2.0-2.6
Hydroxy silicon oil	5.3-6.3	Di-iron trioxide	2.0-2.6
Hydroxy silicon oil	5.3-6.3	Silazane	5.3-7.3
Cumyl peroxide	0.6-0.9	Silazane	5.3-7.3

% represents percetage by weight in the table.

B, sizing material are mixing: above-mentioned various raw materials are required to add in the rubber mixing machine in proportion mixing, following sheet is stand-by.

C, roller core are handled: roller core is gone up lathe, thread turning in accordance with regulations earlier.Through the quartz sand blasting treatment, make the metallic roll wicking surface produce a new surface.After the sandblast, use 120# gasoline cleaning roller wicking surface again.Dry back brush adhesive, dry stipulated time.

D, film is wound on the roller core with full-automatic Wrapping formed machine, reach length, external diameter requirement after, be wrapped with water cloth, rope pressurization again, advance sulfurizing pot vulcanization, vulcanize laggard driving mill and handle, can pack.

Product of the present invention adopts high strength, tear-resistant, resistant to elevated temperatures sizing material to make, and adopts extraordinary adhesive to be brushed on the metal roller core of specially treated, makes sizing material and roller core reach firm bonding.Product is durable in use, has prolonged the service life of rubber roll greatly.

Four, description of drawings

Accompanying drawing is technological process of production figure of the present invention.

Five, the specific embodiment

Sizing compound formula such as table 2:

Table 2

The raw material title	a(g)	b(g)	c(g)
The raw material title	a(g)	b(g)	c(g)	Methyl vinyl silicone rubber	100	100	100
The white carbon black of high reinforcement	30	50	60	Methyl vinyl silicone rubber	100	100	100
The white carbon black of high reinforcement	30	50	60	Di-iron trioxide	3	4	5
Hydroxy silicon oil	8	10	12	Di-iron trioxide	3	4	5
Hydroxy silicon oil	8	10	12	Silazane	8	12	14
Cumyl peroxide	1	1.5	1.7	Silazane	8	12	14

Table 2 provides the embodiment of a, b, three kinds of different sizing material proportionings of c, and g is the unit of weight gram.

Sizing material is mixing: sizing material carries out pressing with 16 o'clock rubber mixing machines, earlier with rubber pressing 4-5 minute, adds di-iron trioxide again, hydroxy silicon oil, silazane pressing 5-6 minute.Add white carbon again, add cumyl peroxide after pressing 8-10 minute, pressing 2-3 minute, use 1mm roll spacing thin-pass 5 times at last, following sheet is stand-by.

Roller core is handled: roller core is gone up lathe, thread turning in accordance with regulations earlier.Through the quartz sand blasting treatment, make the metal roller core produce a new surface.After the sandblast, use 120# gasoline cleaning roller wicking surface again, dry back brush vinyl three tertiary butyl peroxy-silane adhesives, dry 30 minutes.

Roller core twines glue: with automatically extruding Wrapping formed machine, film is wrapped with film by one positive one anti-trend, external diameter reaches the size of regulation.

Twine water cloth: wrap water cloth having twined on the rubber roll of film, overlap joint 1/2.

Rope woolding: twined the rubber roll of water cloth, be wrapped with the rope pressurization again, rope is wanted solid matter.

Sulfuration: behind the rope woolding silica gel roller advanced in the vulcanizing tank and vulcanize 150 ℃ * 10 hours.

Machined into: silica gel roller cooling back is gone up lathe and carried out turning, and is with the emery wheel polishing, qualified on inspection behind the car, can pack.

Claims

A kind of production method of superlarge silica gel roller, it is characterized in that: a, sizing material component and percentage by weight thereof are: methyl vinyl silicone rubber 51.8-66.7, high-reinforcement white carbon black 20.0-31.2, di-iron trioxide 2.0-2.6, hydroxy silicon oil 5.3-6.3, silazane 5.3-7.3, cumyl peroxide 0.6-0.9;

B, sizing material are mixing: above-mentioned various raw materials are required to add in the rubber mixing machine in proportion mixing, following sheet is stand-by;

C, roller core are handled: roller core is gone up lathe earlier, and thread turning in accordance with regulations through the quartz sand blasting treatment, makes the metal roller core produce a new surface, uses 120# gasoline cleaning roller wicking surface again, dry back brush adhesive, dry stipulated time;
