Embodiment 1

[0066] 1. Ingredients: Accurately weigh the required raw materials according to the formula requirements of the above-mentioned flexible foam rubber and plastic insulation products.

[0067] 2. Internal mixing and open refining: the raw materials are separately internally mixed and opened, and rolled into raw material films for later use.

[0068] (1) Weigh NBR: 8.4kg, talcum powder: 6.4kg and PEG: 0.5kg, 4020: 0.2kg, CLP: 20kg, paraffin: 0.9kg, ADDA: 1kg, RD: 0.1kg, C: 0.4kg, PVC : 9kg, zinc borate: 4kg, Sb 2 o 3 : 2kg, Al(OH) 3 : 16kg, CPVC: 10kg, put it into the internal mixing room of the internal mixer and discharge the material after internal mixing. After mixing and slicing through the open mill, it is the No. 1 material. The temperature in the internal mixing room of the internal mixer is 140°C and the material is discharged. The thickness of the film is 10mm, the width is 600mm, and the length is 800mm, and it is stacked after cooling.

[0069] (2) Weigh DOP: 1....

Embodiment 2

[0078] The method of Example 1 was used to prepare flexible foam rubber and plastic thermal insulation products, the difference being that:

[0079] (1) In step 1, weigh the raw materials according to the formula in Table 3, in step 2, banburying and refining 2 o 3 : 2kg, Al(OH) 3 : 15.5kg, CPVC: 9kg.

[0080] (2) Step 2: Mixing and refining (3) The step is: ZnO: 0.5kg, S: 0.7kg, DPG: 0.6kg, ZDMC: 0.9kg and DOP: 1kg, NBR: 2.25kg 1. Talc powder: 0.9 kg is made into a vulcanization accelerator film through banburying and rolling, which is the No. 3 material for subsequent use.

[0081] The obtained product is a flexible foam rubber and plastic insulation product, and the test data of the product are listed in Table 4.

Embodiment 3

[0083] The method of Example 1 was used to prepare flexible foam rubber and plastic thermal insulation products, the difference being that:

[0084] (1) In step 1, weigh the raw materials according to the formula in Table 3, in step 2 banburying and refining, the proportion of flame retardant in step 1 is: zinc borate: 3kg, 2 o 3 : 3kg, Al(OH) 3 : 17kg, CPVC: 8kg.

[0085] (2) Step 2: Mixing and refining (3) The step is: ZnO: 0.6kg, S: 0.6kg, DPTT: 0.3kg, ZDMC: 1.4kg and DOP: 1.5kg, NBR: 2.1 kg, talcum powder: 0.9 kg is made into a vulcanization accelerator film by banburying and rolling, which is used as the No. 3 material for later use.

[0086] The obtained product is a flexible foam rubber and plastic insulation product, and the test data of the product are listed in Table 4.

Abstract

The invention provides a high flame retardancy type soft foam plastic insulation product and a preparation method thereof. The product comprises the following components in parts by weight: 12 to 15 parts of nitrile rubber, 8 to 10 parts of talcum powder, 0.5 to 0.8 parts of polyethylene glycol, 0.2 to 0.4 parts of antiager 4020, 15 to 20 parts of chlorinated paraffin, 0.6 to 0.9 parts of paraffin, 1 to 2 parts of epoxidized soybean oil, 0.1 to 0.3 parts of antiager RD, 0.4 to 0.7 parts of carbon black, 7 to 10 parts of polrvinyl chloride, 26 to 36 parts of fire retardant based on the total amount, 2 to 5 parts of dioctyl ester, 8 to 12 parts of azodicarbonamide, 0.2 to 0.5 parts of stearic acid, 0.4 to 0.7 parts of zinc oxide, 0.4 to 0.7 parts of sulphur, and 1.3 to 1.8 parts of accelerant based on the total amount. By adopting the high flame retardancy type soft foam plastic insulation product, the technical problem that the oxygen index and the smoke density are mutually conflicted in the technological manufacture is solved, and the bottleneck due to mutual limitation is broken through.

Description

technical field [0001] The invention relates to the application field of thermal insulation materials, in particular to application sites for thermal insulation of people's livelihood and public facilities with high requirements for flame retardant effect and good fire safety. Background technique [0002] With the increasing awareness of energy conservation and environmental protection in the society, more and more rubber and plastic thermal insulation materials are used in the fields of people's livelihood and public facilities. However, the flame retardant performance of flexible foam rubber and plastic insulation products is affected by the oxygen index and smoke density index, and the two indexes are contradictory during the product manufacturing process, that is, the oxygen index is generally required to be as high as possible, and the smoke density index is as low as possible. Therefore, most products in the prior art have low oxygen index and poor flame retardancy, w...
