Problems solved by technology

[0003] Although PVC itself has good flame retardant properties, a large amount of plasticizers are added to existing PVC products, which makes PVC products extremely flammable, and PVC products will generate a lot of smoke when burned. The application number for this problem is 201410192430.8 Referring to a flame-retardant PVC artificial leather and its preparation process, it is found through analysis that it still has the following deficiencies: 1. The plasticizer DOP itself has played a great role in promoting the combustion of PVC. In this formula, the plasticizer DOP , The amount of DBP is set at 45~75 parts, and the amount of plasticizer is too much, so a large amount of flame retardant modifier must be added to make up for this defect; 2. The processing temperature of PVC powder with a polymerization degree of 1800 is relatively high, which is not suitable for the processing of foamed products , in actual production, if the temperature is too high, it is easy to foam in advance, and there is a big safety hazard; 3. Add a large amount of flame retardant modifier, the total amount added has exceeded the amount of PVC, and the cost is high; 4. Mixed with a variety of flame retardants Combustible ingredients, and the dosage is large, these ingredients are not as compatible with PVC as calcium carbonate, the processing is very difficult, the product gelling, the dispersion uniformity of each raw material, and the appearance quality of the product surface are difficult to guarantee; 5. Flame retardant modifier A large amount will seriously affect the physical strength of PVC products and limit its scope of use; 6. Add 20 to 30 parts of antimony trioxide to its formula, and some studies believe that when the amount of antimony trioxide exceeds 8PHR, it will be flame retardant The effect will reach saturation, and increasing the dosage will basically not have too much flame retardant effect, on the contrary, it will lead to an increase in smoke generation; 7. The combination of zinc borate, phosphate ester and aluminum hydroxide can effectively flame retardant and smoke suppression, but the actual dosage reaches About 20 parts will cause color change during the processing of PVC products, and the processability will be unstable

preparation example Construction

[0021] The preparation method of the flame-retardant adhesive tape for ships comprises the following steps:

[0022] a. According to parts by mass, put the raw materials into the mixer in the order of polyvinyl chloride resin→liquid stabilizer→epoxidized soybean oil→plasticizer→calcium carbonate→metal hydroxide smoke suppressant→metal antimony flame retardant , within 30s of the feeding process, the slow speed mixing is carried out first, the mixing speed is 400~500r / min, and the high speed mixing is carried out after the feeding is completed, the mixing speed is 900~1000r / min, the current of the mixer is constant with the uniformity of the mixing and the temperature of the material. Change, the initial current will gradually increase by 300A, with the improvement of mixing effect, the current will gradually decrease to 260~280A, the overall mixing time is 300~320s, and the material temperature is 100~120℃;

[0023] b. Automatically discharge the mixed material in step a into ...

Abstract

The invention discloses a flame-retardant adhesive tape for a ship and a preparation method of the flame-retardant adhesive tape. The flame-retardant adhesive tape is prepared from the following raw materials by weight: 100 phr of polyvinyl chloride resin, 20-30 phr of a plasticizer, 4-6 phr of a liquid stabilizer, 3-5 phr of epoxidized soybean oil, 20-30 phr of calcium carbonate, 5-15 phr of a metal hydroxide antismoking agent and 5-15 phr of a metallic antimony series flame retardant. By adjustment to a formula and a processing technology, the flame-retardant adhesive tape for the ship is uniform in plastifying, excellent in flame retardant property and low in flame spreading speed.

Description

technical field [0001] The invention relates to a PVC tape, in particular to a flame-retardant tape for ships and a preparation method thereof. Background technique [0002] With the rise of China's shipbuilding industry, the new technology for interior compartment decoration of ships is to use PVC decorative film composite steel plates. However, once a fire breaks out on a ship, it is very difficult to escape, so SOLAS <<International Convention for the Safety of Life at Sea>> requires The flame retardant performance of PVC film must meet the requirements of low flame propagation, and its flame retardant test must pass the Part5 test of the International Maritime Organization <<2010 International Fire Test Application Rules>>. [0003] Although PVC itself has good flame retardant properties, a large amount of plasticizers are added to existing PVC products, which makes PVC products extremely flammable, and PVC products will generate a lot of smoke wh...
