Description

Polystyrene micro-foaming material with high strength, low thermal expansion and high and low temperature resistance
Technical Field
The invention belongs to the technical field of foaming materials, and particularly relates to a polystyrene micro-foaming material with high strength, low thermal expansion and high and low temperature resistance, and a preparation method of the foaming material.
Background
Compared with wood plastic products, the polystyrene micro-foaming material has the advantages of low cost, good long-term water resistance, light weight, no mildew, good application durability and the like, so the application is wider, such as patent documents CN201110222462.4 and CN20110205050554. X, but the general-purpose polystyrene resin material is not suitable for members with larger temperature difference and bearing function because a large amount of impact-resistant polystyrene is used in the formula, the bending strength and tensile strength of the final section bar are further reduced, the bending strength and the tensile strength are lower, the strength is generally lower than 20Mpa, the strength is lower than that of the wood plastic products, the material is easy to deform, the thermal expansion and contraction are obvious, the linear thermal expansion coefficient is larger, the high and low temperature resistance is poor, and the application of the polystyrene foaming material in the related fields is limited to a large extent.
Other patent documents such as CN111138773A, CN110128759A, CN110105683a and the like focus on solving the light weight, flexibility, flame retardance and other performances of polystyrene foam materials, and at present, there are few patent documents or journal documents related to polystyrene foam materials which solve the problems of foam material strength, linear thermal expansion and high and low temperature resistance at the same time.
In view of the fact that the foamed material cannot simultaneously satisfy the above-mentioned high strength, low thermal expansion and high and low temperature resistance, in the practical construction process, a material having the above-mentioned properties is needed to be suitable for applications in different environments, and therefore, improvement is needed to overcome the above-mentioned drawbacks, and a polystyrene micro-foamed material having high strength, low thermal expansion and high and low temperature resistance is invented.
Disclosure of Invention
In order to solve the technical problems, the invention provides a polystyrene micro-foaming material which is suitable for the environment with larger outdoor temperature difference, has high strength, low thermal expansion and high and low temperature resistance.
In the invention, the general-grade polystyrene is matched with the methyl methacrylate-butadiene-styrene terpolymer and the styrene-maleic anhydride copolymer to be used as the styrene base resin, the impact-resistant polystyrene with low bending resistance and tensile strength is not used, and under the condition that the rigidity matching of the general-grade polystyrene is utilized to obtain the methyl methacrylate-butadiene-styrene terpolymer which meets the basic requirements on strength and toughness, the active carboxyl in the styrene-maleic anhydride copolymer, the E-44 epoxy resin, the triglycidyl isocyanurate and the epoxidized soybean oil are utilized to be cured in the molding process, so that the high strength (bending strength and tensile strength), the lower low linear thermal expansion coefficient and the excellent high and low temperature resistance are obtained.
The three base resins are polystyrene or copolymer of polystyrene, the compatibility is good, and the used compatilizer is epoxy soybean oil, which not only plays roles in lubricating and increasing the compatibility of each component in the melt mixing stage, but also contains epoxy groups, and can participate in curing with carboxyl in the styrene-maleic anhydride copolymer in the later stage, so that the product with high bending strength, high tensile strength and excellent high and low temperature resistance is finally obtained.

table 1 amounts (parts) of raw materials used in the examples
In Table 1, the foaming agent is selected from sodium bicarbonate or ammonium bicarbonate, and the foaming effects of the two are hardly different, and one of the two is selected;
the ultraviolet absorbent is 2, 4-dihydroxybenzophenone;
the compatilizer is epoxidized soybean oil;
the antioxidant is 1010.
Comparative example 1
Styrene-maleic anhydride copolymer (SMA) was not used, the remainder being the same as in example 1;
comparative example 2
Triglycidyl isocyanurate was not used, and the rest was the same as in example 1;
comparative example 3
E-44 epoxy resin was not used, and the rest was the same as in example 1;
comparative example 4
The product of example 1 in cn201102060554. X was used as comparative example 4.
Example 9
The composite materials prepared in the examples and the comparative examples are subjected to performance detection of tensile strength according to the method of the 4.24 th part in GB/T17657-2013 standard; flexural strength test was carried out according to the method of GB/T1696-2001; the linear thermal expansion coefficient is detected according to the method of GB/T29418-2012, and the temperature range is: -30 ℃ to 40 ℃; the high and low temperature resistance test is carried out according to section 6.5.9 of GB/T24508-2009.
The test results are shown in table 2 below.
Table 2 comparison of the properties of the foaming materials in examples and comparative examples
As can be seen from Table 2, the foaming materials in examples 1 to 8 of the present invention have high flexural strength and tensile strength, and relatively low thermal expansion coefficient, and particularly, after high and low temperature resistance test (-30 ℃ to 40 ℃), the surface of the foaming materials is substantially crack-free, and the dimensional change is less than 0.5mm, so that the foaming materials can be used in areas with large temperature difference on load-bearing supports.
In comparative example 1, since the styrene-maleic anhydride copolymer is not used, the E-44 epoxy resin and triglycidyl isocyanurate cannot be cured and crosslinked, so that the whole system becomes a complete thermoplastic system, the strength is obviously reduced, the linear thermal expansion coefficient is higher, and the dimensional change is larger after the high-low temperature resistance performance test.
In comparative examples 2 and 3, the E-44 epoxy resin and triglycidyl isocyanurate were not used, which resulted in insufficient crosslinking density after molding and curing, and the material strength after curing and molding was reduced to some extent, and the linear thermal expansion coefficient was also increased, and the dimensional change after high and low temperature resistance test was also large due to insufficient crosslinking degree.
In comparative example 4, the product of example 1 of patent document 201102060554. X was used, and the product was a fully foamed product prepared mainly from general-purpose styrene and impact-resistant styrene, and therefore, the product was low in strength, high in linear thermal expansion coefficient, and significant in cracks due to excessive deformation in high and low temperature performance test, and large in dimensional change, and could not be used in a region where the temperature difference was large.
Through the analysis and comparison, the foaming material has the characteristics of high strength, low thermal expansion and excellent high and low temperature resistance, has basically no crack on the surface even in the temperature range of-30 ℃ to 40 ℃, has the size change of less than 0.5mm, is suitable for being used as a member with a bearing function in an environment with a larger temperature difference, and widens the application range compared with similar products.
