Abstract
The invention discloses a flame-proof and electrostatic resistant unsaturated polyester resin for manufacturing glass reinforced plastic gas pipes of coal mines, which comprises the following ingredients (by weight portions): unsaturated polyester resin 100 parts, decabromodiphenyl oxide 22-26 parts, antimony trioxide 3-6 parts, and acetylene carbon black 1.5-3 parts.
Description
Technical field
The invention belongs to the macromolecule chemical industry field, especially relate to a kind of fire-retardant, antistatic unsaturated polyester resin that additive preparation becomes that add, be applicable to and make underground mine use glass reinforced plastic gas pipe.
Background technology
Fire-retardant, antistatic unsaturated polyester resin is a main raw material(s) of making underground mine use glass reinforced plastic gas pipe, and fire-retardant, the antistatic property of glass reinforced plastic gas pipe all fire-retardant, the antistatic unsaturated polyester resin after solidify obtains.At present, the producer of domestic production glass reinforced plastic gas pipe is a lot, but the glass reinforced plastic gas pipe of producing all has the shortcoming of poor mechanical property mostly, the gas pipe poor mechanical property is because make the fire-retardant of gas pipe, the mechanical properties decrease of antistatic unsaturated polyester resin causes, because unsaturated polyester resin itself does not have fire-retardant, anlistatig performance, so, generally all adopt and add fire retardant, it is fire-retardant that the method for static inhibitor obtains unsaturated polyester resin, antistatic property, but the mechanical property of its unsaturated polyester resin goods has descended greatly when additive adds.The reason of mechanical properties decrease mainly is: 1, in order to satisfy the requirement of coal-mining industry ministerial standard " underground mine use plastics tubing safety performance inspection specification " (MT 181-88) regulation, the addition of fire retardant, static inhibitor is bigger, has influenced the mechanical and physical performance of glass fiber reinforced plastics product; 2, some fire retardants, static inhibitor have certain inhibition, make the degree of cure of unsaturated polyester resin be difficult to reach requirement, have influenced the mechanical property of glass fiber reinforced plastics product.The decline of goods mechanical property, cause the underground mine use fiber reinforced plastic pipe in use to cause accident to take place easily, as because glass reinforced plastic gas releasing pipe bears the negative pressure ability drop and destroys structural pipe wall easily, cause serious consequences such as pipeline breaking, damage, influenced the effect of gas drainage.
Summary of the invention
The purpose of this invention is to provide a kind of fire-retardant, antistatic unsaturated polyester resin prescription, when unsaturated polyester resin obtains fire-retardant, antistatic property, make its goods have higher mechanical property.
The object of the present invention is achieved like this:
A kind of fire-retardant, antistatic unsaturated polyester resin, formed by following compositions in weight portion:
100 parts of unsaturated polyester resins
Decabromodiphenyl oxide 22-26 part
Antimonous oxide 3-6 part
Shawinigan black 1.5-3 part
Prescription is preferably:
100 parts of unsaturated polyester resins
Decabromodiphenyl oxide 23-26 part
Antimonous oxide 4-5 part
Shawinigan black 1.5-3 part
Best prescription is:
100 parts of unsaturated polyester resins
25 parts of decabromodiphenyl oxides
5 parts of antimonous oxides
3 parts of Shawinigan blacks.
Production method of the present invention is very simple, is about to each component and takes by weighing by described weight ratio, adds decabromodiphenyl oxide, antimonous oxide, Shawinigan black successively in unsaturated polyester resin, and stirring by stirrer gets final product.
After this prescription process our company test of many times, on the basis of great number tested data, finally determined optimum formula.This prescription has following characteristics:
The one, decabromodiphenyl oxide is a kind of addition type efficient flame-retarding agent, the high brominated amount of tool, Heat stability is good, the characteristics that addition is little.The decabromodiphenyl oxide physicochemical characteristic is as follows:
