Embodiment 1

[0033] (1) Preparation of carboxyl-containing chlorinated paraffin 42: Dissolve 20 g of chlorinated paraffin 42 in 200 mL of acetone, stir to dissolve, add 20 g of p-hydroxybenzoic acid and 30 g of potassium carbonate, and react at 55° C. for 30 h under nitrogen protection. After the reaction, the pH was adjusted to 3.0 with hydrochloric acid, and then extracted with ethanol, and the product was vacuum-dried at 100° C. for 5 h to obtain carboxyl-containing chlorinated paraffin 42.

[0034] (2) Preparation of chlorinated paraffin 42 containing acid chloride: add 70 mol of chlorinated paraffin 42 containing carboxyl to the reaction kettle, dropwise add 120 mol of thionyl chloride, stir and heat up to reflux, and react for 6 hours to obtain chlorinated paraffin 42 containing acid chloride .

[0035] (3) Preparation of hydroxyl-terminated phosphorus-containing chlorinated paraffin 42: add 100mol [(6-oxo-6H-dibenzo[C,E][1,2]oxaphosphorinane-6- Base) methyl] butanediol and an appro...

Abstract

The invention discloses a heat-resistant and flame-retardant polyvinyl chloride leather material, which comprises a novel flame retardant. A preparation method of the flame retardant comprises the following steps of: reacting chlorinated paraffin with p-hydroxybenzoic acid to prepare carboxyl-containing chlorinated paraffin, acylating the carboxyl-containing chlorinated paraffin to obtain acyl chloride-containing chlorinated paraffin, carrying out esterification reaction on the acyl chloride-containing chlorinated paraffin and [(6-oxo-6H-dibenzo [C, E] [1, 2] oxophosphahexylhexane-6-yl) methyl] butanediol to obtain hydroxyl-terminated phosphorus-containing chlorinated paraffin, acylating the hydroxyl-terminated phosphorus-containing chlorinated paraffin, and reacting the acylated hydroxyl-terminated phosphorus-containing chlorinated paraffin with tris (2-ethoxyl) isocyanurate and tetrafluoroterephthaloyl dichloride to obtain the novel flame retardant. When the flame retardant is used for preparing the heat-resistant and flame-retardant polyvinyl chloride leather material, it is ensured that the material has good mechanical properties, processability and high-temperature resistance, also has very good flame retardancy and is low in cost.

Description

technical field [0001] The invention relates to a heat-resistant and flame-retardant polyvinyl chloride leather material and a preparation method thereof, belonging to the technical field of heat-resistant and flame-retardant polymer materials. Background technique [0002] Imitation leather is made of various PVC and PU foams or films on a textile or non-woven fabric base. It can be customized according to different strengths, abrasion resistance, cold resistance, color, gloss, Patterns and patterns are required to be processed. It has the characteristics of a wide variety of designs and colors, good waterproof performance, neat edges, high utilization rate and relatively cheap price compared with real leather. It is a kind of material that has been very popular in the early days until now, and is widely used to make various leather products, or some genuine leather materials. Because its surface is very delicate, it can be flawless, and it is relatively durable, so it is ...
