Abstract
The invention discloses a composite foaming agent for sponge rubber. The agent consists of the following raw materials by weight: 6-12 parts of modified 4,4 '-oxydibenzenesulfonyl hydrazide, 4- 8 parts of azo barium dioctyl phthalate, 2-5 parts of 1,4-disulphohydrazide benzene, 1-2 parts of 2-mercaptobenzothiazole, 4-8 parts of ammonium carbonate, 20-30 parts of ethylene glycol, 5-8 parts of triethanolamine, 2-5 parts of boric acid, 1-2 parts of zinc stearate and 1-2 parts of nanometer zinc oxide. The foaming agent provided by the invention has excellent foaming capacity, high foaming rate and process stability; and the produced foam has good temperature adaptability, dispersion uniformity, low cost and easy usage. The sponge rubber material prepared from the foaming agent provided by the invention has uniform and beautiful appearance, good mechanical properties, low density and fine and uniformly dispersed micropores.
Description
Technical field
The present invention relates to a kind of whipping agent, be specifically related to a kind of rubber sponge composite foamable agent.
Background technology
Rubber sponge is the general name with various rubber of cell structure, makes after generally adopting chemical foam blowing agent.Because microvoid structure is with the typical characteristics of solid and gas, the rubber sponge quality that therefore has microvoid structure is little, heat insulation, sound insulation, performance and mechanical damping characteristic are good.Rubber sponge is mainly for the manufacture of the weather strip of automobile, cushion rubber bumper, the construction work goods such as thermal insulation material, cushioning material, simple diving clothes and rubber overshoes with gasket seal, light current parts.And whipping agent is most important a kind of auxiliary agent in the rubber sponge, and the kind of whipping agent, quantity have a direct impact the physical and mechanical properties of foam, foam density, temperature tolerance etc.There are problems such as expansion ratio is lower, less stable in the whipping agent of rubber sponge use at present, directly has influence on the performance of rubber item, causes product strength low, the quality instability, and general technical quality level is low.Therefore, it is very necessary and urgent conducting a research at the existing problem of whipping agent.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, the rubber sponge composite foamable agent of a kind of expansion ratio height, good processing stability is provided.
The technical solution used in the present invention is as follows:
A kind of rubber sponge composite foamable agent, formed by the raw material of following weight part:
Preferably, a kind of rubber sponge composite foamable agent, formed by the raw material of following weight part:
Described modification 4,4 '-OBSH is made by following method:
(1) take by weighing 10-15 part mesoporous silicon dioxide micro-sphere and join in 100 parts of aqueous ethanolic solutions, wherein the volume ratio of second alcohol and water is 9:1, behind the ultrasonic 20-30min, adds 1-2 part silane coupling agent KH-570 again, stirs 10-12h, filters, and suction filtration becomes wet cake stand-by;
(2) take by weighing 4 of 5-8 part, 4 '-OBSH is dissolved into extremely clarification in 40-50 part acetone, adds the wet cake that step (1) makes, and stirs 2-3h, and is dry under room temperature behind the suction filtration, namely gets modification 4,4 '-OBSH.
Beneficial effect of the present invention:
The whipping agent that the present invention produces has good foaming power, the expansion ratio height, and processing stability, the foam of generation has good thermal adaptability and dispersing uniformity, and low cost is easy to use.The rubber sponge texture material that adopts whipping agent of the present invention preparation is attractive in appearance, good mechanical properties evenly, and density is little, and micropore is fine and closely woven to be uniformly dispersed.
Embodiment
The present invention is further illustrated below in conjunction with embodiment.
