Abstract
The invention relates to polyurethane flame-retardant resilient foam. The polyurethane flame-retardant resilient foam has good resilience mechanical properties. The polyurethane flame-retardant resilient foam has uniform pores. A rolling experiment proves that compared with the traditional resilient foam, the polyurethane flame-retardant resilient foam has a longer service life and a faster rebound rate. The polyurethane flame-retardant resilient foam comprises 6-12 parts of silica nanopowder and overcomes the defect of no ultraviolet absorption component in the traditional resilient foam. When being used outside, the polyurethane flame-retardant resilient foam is not fast aged under UV. The polyurethane flame-retardant resilient foam saves a protective sleeve cost and widens a resilient foam application range.
Description
Technical field
The present invention relates to a kind of polyurethane flame-proof rebound foam, belong to Material Field.
Background technology
Urethane foam is a kind of important synthetic materials, has that porousness, relative density are little, specific tenacity high, according to the variation of raw materials used difference and formula, can be made into common soft bubble, high rebound foam and hard bubbles etc.Urethane foam is carried out chemical reaction in the short period of time at the utmost point by plurality of raw materials, and by liquid, become colloid and become superpolymer again, is experiencing the complex processes such as foaming, gel therebetween.Therefore, must rely on suds-stabilizing agent to play regulatory role, just can make uniform in foaming, foam stabilization, make the uniform foams of abscess.Silicon foams stablizer, as a kind of tensio-active agent, can significantly reduce the surface tension of foaming system, is widely used.
Therefore the organic silicon surfactant that application has a special performance is developed stablizer for polyurethane foamed material because its effect is remarkable, has brought the innovation of polyurethane foamed material moulding process, makes polyurethane industrial obtain tremendous development.In recent years, the foam applications of high resilience is extensive, but general high rebound foam does not have fire retardancy, and the high resilience with the foam of fire retardancy can be not ideal enough.
Summary of the invention
The technical problem to be solved in the present invention is: propose a kind ofly have compared with high flame retardant ability, anti-ultraviolet ageing and have the polyurethane flame-proof rebound foam of learning performance compared with high resilience; this polyurethane flame-proof rebound foam can effectively be avoided the aging of ultraviolet so can exposedly use when routine use; do not need coated protecting materials, reduced cost.
The present invention is that the technical scheme that solves the problems of the technologies described above proposition is: a kind of polyurethane flame-proof rebound foam, is comprised of the component mixed foaming of following mass parts:
Surplus is PVC plastics micelle aggregate, and the particle diameter of described PVC plastics micelle is 8～12mm.
Further, wherein said vinylformic acid is as linking agent, and described dibutyl tin laurate is as tin catalyst, and described diethanolamine is as amine catalyst, and described dimethyl siloxane is as suds-stabilizing agent.
Further, the mass parts of silica nanometer powder is 8.
Further, described PVC plastics micelle aggregate is pulverized and is made by pulverizer.
The invention has the beneficial effects as follows:
Polyurethane flame-proof rebound foam provided by the invention has following advantage:
1), the polyurethane flame-proof rebound foam in the present invention has preferably resilience mechanical property, in the present invention, the pore of polyurethane flame-proof rebound foam is even, through roller compaction, verifies that the relatively traditional rebound foam of polyurethane flame-proof rebound foam in real the present invention has longer work-ing life and rebound velocity faster;
2) polyurethane flame-proof rebound foam, in the present invention has also comprised the silica nanometer powder of 6-12 part, has made up the defect of not inhaling purple composition in traditional rebound foam, when the present invention is during in outdoor application, has avoided quick UV aging; In addition, also saved the cost of protective sleeve, made the use range of rebound foam more extensive.
3), the present invention is by adopting described vinylformic acid as linking agent, described dibutyl tin laurate is as tin catalyst, described diethanolamine is as amine catalyst, described dimethyl siloxane is as suds-stabilizing agent, raw material easily obtains, with low cost.
