Embodiment 1

[0026] A kind of manufacture technology of organosilicon modified Ms pavement wall building material, concrete steps are as follows:

[0027] 1. HCH obtained from organic silicon industry low-quality materials and photovoltaic industry low-quality materials 3 SiCl 2 Carry out esterification alcoholysis:

[0028]

[0029] HCH 3 Si(OC 2 h 5 ) 2 +2HCl+2OH - →HCH 3 Si(OC 2 h 5 ) 2 +2H 2 O+2Cl - ②

[0030] The substance obtained in reaction ② is separated to obtain HCH 3 Si(OC 2 h 5 ) 2 substance.

[0031] In this example, the organic silicon industry waste and the photovoltaic industry low waste refer to the waste generated in the industrial production process, the waste is converted into organic silicon, and the obtained organic silicon is used as raw material to turn waste into treasure, and after the reaction The produced material can be recycled, no pollution, environmental protection and energy saving.

[0032] 2. Anhydrous tung oil and methyldiethoxysi...

Embodiment 2

[0046] In this example, the composition and content of the ingredients in the building material manufacturing process are the same as in Example 1, the difference is that the reaction conditions are changed: in step 2, the anhydrous tung oil is vacuumed at 50 ° C, dehydrated for 1 hour, and methyl diethoxy is added After silane, the temperature was raised to 55°C, and finally the reaction was refluxed at 80°C for 2h.

[0047] In step 3, the allyl polyether diol is vacuumed at 65°C for 1 hour, after adding methyldiethoxysilane, the temperature is raised to 70°C, and then the catalyst is added, and finally reacted at 75°C for 1 hour.

[0048] In step 4, the reactants obtained in step 2 and step 3 were uniformly mixed at 85°C, reacted for 1 hour, added epoxy resin, cooled to 45°C, and discharged to obtain the base material.

[0049] The base material obtained in this embodiment is light yellow liquid with high viscosity, good bonding strength, average elongation and easy coloring...

Embodiment 3

[0051] In this example, the composition and content of the ingredients in the building material manufacturing process are the same as in Example 1, the difference is that the reaction conditions are changed: in step 2, the anhydrous tung oil is vacuumed at 70 ° C, dehydrated for 1 hour, and methyl diethoxy is added After silane, the temperature was raised to 65°C, and finally the reaction was refluxed at 80°C for 2h.

[0052] In step 3, the allyl polyether diol is vacuumed at 55°C for 1 hour, and after adding methyldiethoxysilane, the temperature is raised to 60°C, then the catalyst is added, and finally reacted at 70°C for 1 hour.

[0053] In step 4, the reactants obtained in step 2 and step 3 were uniformly mixed at 80°C, reacted for 1 hour, added epoxy resin, cooled to 40°C and discharged to obtain the base material.

[0054] The base material obtained in this embodiment is a light yellow transparent liquid with high viscosity, average bonding strength, high elongation and ...

Abstract

The invention discloses a silicone modified Ms pavement and wall building material and a manufacturing process thereof, wherein the raw material component comprises anhydrous tung oil, silicone, allylpolyether diol, epoxy resin, catalyst, silane coupling agent. The manufacturing process includes the following steps: first, anhydrous tung oil and silicone undergo addition reaction to produce tungoil addition products under the action of catalyst; next, allyl polyether diol and silicone undergo addition reaction to produce polymer products under the action of catalyst; then by mixing the tungoil addition products and the polymer, and by adding epoxy resin to the mixture, base materials are produced; finally, the base materials are taken, silane coupling agent and catalyst are added to besubjected to reaction, and the mixture is uniformly stirred to obtain building materials. The silicone modified Ms pavement and wall building materials have the advantages of being strongly weather resistant, waterproof and anti-fouling, environmentally friendly and non-toxic, and of good adhesion, good air permeability, heat insulation and preservation, strong practicability, and ability to be widely promoted and used.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to an organosilicon-modified Ms pavement and wall building material and a manufacturing process. Background technique [0002] Building materials have a history of thousands of years, especially pavement and wall materials, which can be seen everywhere in people's daily life. Currently commonly used building materials include soil, lime, cement, asphalt, etc., but they all have defects in aesthetics and environmental protection. For the environmentally friendly, healthy and beautiful living environment pursued by modern people, the original building materials cannot satisfy. [0003] The main substance of some pavement building materials in the prior art is epoxy polyurethane, and epoxy polyurethane will release low-molecular isocyanate groups during the curing process, and the isocyanate groups will react with substances in the air to form isocyanates. Isocyanates are ...
