Abstract
The invention discloses a high-weather-resistance modified plastic. The high-weather-resistance modified plastic is prepared from polyvinyl chloride, phenolic resin, aluminum powder, silica powder, a dispersing agent, a heat stabilizer and a plasticizing agent. Due to the fact that modified phenolic resin is added into the plastic and combined with silica powder and nano-aluminum particles, the structural property of the plastic can be improved, and the weather resistance of the plastic can be greatly improved. The production technology is simple and low in cost, and the prepared plastic has excellent heat stability.
Description
Technical field
The present invention relates to plastic production field, particularly relate to a kind of modified plastics of high-weatherability.
Background technology
General igelite on market, the degree of branching is less, relative density about 1.4, second-order transition temperature 77 ~ 90 DEG C, about 170 DEG C start to decompose, to the poor stability of light and heat, more than 100 DEG C or through long-time exposure in sunshine, will decompose and produce hydrogenchloride, and autocatalytically is decomposed further, cause variable color, physical and mechanical properties also declines rapidly, the comparatively large and shock resistance of fragility, weathering resistance are poor, and these deficiencies make its application be restricted.
Summary of the invention
The object of this invention is to provide a kind of modified plastics of high-weatherability, be achieved through the following technical solutions:
A modified plastics for high-weatherability, is made up of following composition: polyvinyl chloride 40 parts, 30 parts, resol, aluminium powder 8 parts, silica flour 6 parts, dispersion agent 3 parts, thermo-stabilizer 2 parts, 2 parts, softening agent by weight.
Further, described aluminium powder adopts the heating in water bath process of 60-65 DEG C after 1-1.5 hour, dry.
Further, described dispersion agent is glyceryl monostearate.
Further, described thermo-stabilizer is calcium stearate.
Further, described softening agent is citrate.
Further, described resol is through modification: the dodecyltrimethoxysilane Homogeneous phase mixing under alkaline environment by resol and weight part being 5 parts, initial heating temperature to 300 DEG C, continue after 20 minutes, add the boric acid that weight part is 3 parts, continue slowly to heat, in 2 hours, temperature is increased to till 500 DEG C, start Slow cooling, when being cooled to 187 DEG C, keeping after 20 minutes, continuing to be cooled to 132 DEG C, keep 20 minutes, till last cool to room temperature.
Further, the resol through modification is heated to together with silica flour can Homogeneous phase mixing to together, then add the nano aluminum particle that weight part is 4 parts, mix; The granularity of described nano aluminum particle is 15-18nm.
The invention has the beneficial effects as follows: the present invention is directed to prior art above shortcomings, the present invention is by adding the resol through modification in the plastic and being combined with silica flour, nano aluminum granule by modified resol, the textural property of plastics can be improved, improve the weathering resistance of plastics greatly; Production technique of the present invention is simple, and cost is low, and the plastics of making have excellent thermostability.
Embodiment

A modified plastics for high-weatherability, comprising:
1) take respectively by weight, polyvinyl chloride 40 parts, 30 parts, resol, aluminium powder 8 parts, silica flour 6 parts, dispersion agent 3 parts, thermo-stabilizer 2 parts, 2 parts, softening agent.
2) by polyvinyl chloride, resol, aluminium powder, silica flour mixing, uniform stirring is after 30 minutes, remix dispersion agent, thermo-stabilizer and softening agent, add in forcing machine, extruding plasticizing and uniformly plastic grain, the processing condition extruding process are: a district temperature 210-220 DEG C, two district temperature 220-240 DEG C, three district temperature 240-260 DEG C, four district temperature 260-270 DEG C, the residence time is 2 minutes.
The performance parameters of plastics of the present invention:
| Density g/cm3 | Elongation at break % | Dielectric strength MV/m | Low-temperature impact embrittlement temperature DEG C | |
| Plastics of the present invention | 1.42 | 287.4 | 18.6 | ≤-20 |
Table 1
Modified plastics performance test of the present invention:
Table 2
As can be seen from Table 2, plastics of the present invention are much more superior than general igelite in performance.
