Problems solved by technology

The disadvantage of this method is: the flame retardant effect is not ideal
The disadvantage of this method is: the loss of flame retardant is more serious
[0014] 1. The amount of flame retardant added is large, the flame retardant effect of paper is poor, the weight gain is obvious, and it is easy to return halogen and absorb moisture;
[0015] 2. Some flame retardants (such as decabromine, organic phosphine and halogenated hydrocarbons, etc.) have certain toxicity. When these flame retardants are heated, they will produce toxic gases or substances, and their environmental protection performance is poor;
[0016] 3. Some flame retardants are unstable. These flame retardants undergo chemical changes under the action of heat and light, which reduces the flame retardant effect

Abstract

The invention provides a flame retardant for the filter paper of a filter and a preparation method and application thereof. The flame retardant comprises, by weight, 50 to 60 parts of ammonium polyphosphate, 40 to 45 parts of tritolyl phosphate, 20 to 30 parts of melamine, 60 to 65 parts of glycol and 180 to 220 parts of water. The flame retardant has the advantages of economic composition, a good flame retardation effect and long-lasting action. The preparation method is a traditional mixing and heated stirring method and has the advantages of simple process and a small amount of used equipment. The application of the flame retardant is as follows: three traditional methods consisting of electrostatic spraying, dip-coating and brush coating are utilized for coating the flame retardant on the surface of the filter paper of the filter so as to form a layer of flame retardant membrane, process temperature is 110 to 120 DEG C, and process time is 10 to 30 s. The membrane enables the filter paper of the filter to have good flame resistance and the service life of the filter to be prolonged accordingly.

Description

technical field [0001] The present invention relates to a treatment agent, more specifically, the present invention relates to a filter paper flame retardant treatment agent, at the same time, the present invention also relates to a preparation method and application of the filter filter paper flame retardant treatment agent . Background technique [0002] Paper is generally made of plant fibers, and plant fibers are mainly glucose condensation products, which are flammable. The flammability of plant fibers determines the flammability of paper. From a safety point of view, the flammability of paper determines the limitations of its use in some special occasions. [0003] The crankshaft and camshaft of the automobile engine have a high rotational speed, which makes the circulation temperature of the combustion medium inside the engine relatively high. For the safety of the automobile, higher requirements are put forward for the flame retardancy of the automobile filter pape...
