Abstract

The invention discloses high-temperature-resistant resin, comprising the following components in percent by weight: 45-60 percent of unsaturated polyester, 10-20 percent of rock wool, 5-8 percent of copper naphthenate, 2-5 percent of cobalt isooctanoate, 20-30 percent of calcium carbonate, 1-5 percent of talc powder and 8-12 percent of silicon dioxide. Due to low viscosity and good wetting property, the high-temperature-resistant resin provided by the invention has good penetration property, adjustable viscosity and long life cycle, can be widely used for processes such as mechanical winding, casting, hand lay-up and die pressing and has a wide market value and large market potential.

Description

Fire resistant resin

Technical field

The present invention relates to technical field of polymer materials, more particularly, it is a kind of fire resistant resin.

Background technology

Along with the continuous development of corrosion and protection and the raising of industrialization degree, the Application Areas of matrix material is also more and more wider, applying working condition, and medium becomes increasingly complex, and use temperature is also increasingly high, and market is also increasingly high to its performance demands.

At present, the field adopts the high-property resin composite material material more single both at home and abroad, be main with unsaturated polyester, vinyl ester resin, tough epoxy resin material mainly, but all there is weak point in various degree in these materials.Like unsaturated polyester, fragility is big, and use temperature is low, and bonding strength is low; Though vinyl ester resin has good toughness, bonding strength is good, solidify advantages such as back toxicity is little, there are shortcomings such as use temperature is low; Epoxy resin though have good toughness, bonding strength advantages of higher, exists weathering resistance poor; Be prone to efflorescence, viscosity is big, and wettability is poor; Under comparatively high temps, to bear than strong corrosive medium as relatively poor than the ability of strong acid, alkali and solvent etc., curing system toxicity is big; Curing cycle is long, shortcomings such as post-treatment expense height.Therefore, traditional matrix material far can not satisfy market to the increasingly high requirement of its performance.

Summary of the invention

For overcoming the weak point that prior art exists, it is good, normal temperature solidified to the purpose of this invention is to provide a kind of heat-resistant fireproof, corrosion-resistant, HS, performance of technical process, solidifies nontoxicity, the fire resistant resin that bonding strength is high.

For achieving the above object; The technical scheme that the present invention taked is: a kind of fire resistant resin, each component and weight percent content thereof are respectively: unsaturated polyester resin 45-60%, rock wool 10-20%, copper naphthenate 5-8%, cobalt iso-octoate 2-5%, lime carbonate 20-30%, talcum powder 1-5%, silicon-dioxide 8-12%.

Fire resistant resin provided by the invention compared with prior art; It is good, normal temperature solidified to have heat-resistant fireproof, corrosion-resistant, HS, performance of technical process, solidifies nontoxicity, characteristics such as bonding strength height; Not only technical process is simple, with short production cycle; And in the resin building-up process, make full use of the heat that chemical reaction produces, the energy-conservation energy and do not have the three wastes and produce.Fire resistant resin provided by the present invention is because viscosity is little, wettability good; Therefore various fibre products had good penetration property; And viscosity adjustable; But life cycle is long, can be widely used in technologies such as mechanical winding, casting, hand paste, mold pressing, has marketable value and huge market potential widely.

Embodiment

Below in conjunction with embodiment the present invention is done further detailed description:

Embodiment 1: a kind of fire resistant resin of the present invention takes by weighing each feed composition by following weight proportion: unsaturated polyester resin 50%, rock wool 10%, copper naphthenate 5%, cobalt iso-octoate 2%, lime carbonate 20%, talcum powder 5%, silicon-dioxide 8%.

The preparation method of this fire resistant resin, its concrete steps are following:

1, gets 50% unsaturated polyester resin and add in the bucket, add 10% rock wool, 5% copper naphthenate, 2% cobalt iso-octoate, 20% lime carbonate, 5% talcum powder and 8% silicon-dioxide more respectively;

2, with stirrer to above-mentioned raw materials stir 30 minutes even fully to raw material; Fire resistant resin promptly can be made into.

Embodiment 2: a kind of fire resistant resin of the present invention takes by weighing each feed composition by following weight proportion: unsaturated polyester resin 45%, rock wool 11%, copper naphthenate 7%, cobalt iso-octoate 4%, lime carbonate 22%, talcum powder 2%, silicon-dioxide 9%.

Can obtain fire resistant resin according to above-mentioned preparation method.

Like the prescription of above-mentioned embodiment, adopt other fire resistant resins that obtained with the same or similar prescription of this embodiment, all within protection domain of the present invention.

Claims

1. fire resistant resin, it is characterized in that: each component and weight percent content thereof are respectively: unsaturated polyester resin 45-60%, rock wool 10-20%, copper naphthenate 5-8%, cobalt iso-octoate 2-5%, lime carbonate 20-30%, talcum powder 1-5%, silicon-dioxide 8-12%.
