Description
Technical field
The present invention relates to a kind of electric porcelain insulator and produce materials, be specifically related to a kind of electroceramics cement glue composite material type formula.
Background technology
Along with the development of China's power construction, ultra-high voltage, large span, long distance power transmission obtain universal rapidly, and the electrotechnical porcelain product played an important role in project of transmitting and converting electricity is widely used.Electroceramics cement glue is the important component part of electrotechnical porcelain product, be mainly used in the electric porcelain insulator such as suspension type, line pole type, it plays forms holistic effect by porcelain piece and metal-ware, run because electric porcelain insulator hangs on high-tension bus-bar, electric porcelain insulator go wrong then whole circuit by power-off, huge numbers of families are by instantaneous power failure, very large on the life impact of people.In prior art, electrotechnical porcelain product also exists following problem in mucilage binding: after product mucilage binding, cementing agent early strength is less, has had a strong impact on production efficiency; In addition in order to ensure the intensity of mucilage binding, in traditional cement glue, the consumption of cement is very large, causes cement glue cost higher.
Summary of the invention
The technical problem to be solved in the present invention is to provide one can improve cementing agent early strength.
To achieve these goals, the invention provides a kind of electroceramics cement glue composite material type formula, mixed by the component of following mass parts and form: aluminosulfate cement: 100, mucilage binding quartz sand: 45 ~ 55, water: 27, admixture: 0.4 ~ 0.5, silicon powder: 2 ~ 3, glass fibre: 0.08 ~ 0.11;
Wherein, the fineness≤0.09mm of aluminosulfate cement 100% particle; The particle of mucilage binding quartz sand 0.3 ~ 1mm is greater than 80%; The pH value of water is 7.0 ~ 7.2, water temperature < 35 DEG C.
Wherein, mucilage binding quartz sand is a kind of quartz sand raw material through processing, and its chemical composition is Fe
2o
3be 0.4%, SiO
2be 95.8%, wherein mechanical iron level about 0.015%.
Nearly 30 batches of formula Physicochemical test have successively been carried out in application, and test method is undertaken by Xian Electrical Ceramics Research Institute " the electroceramics inspection of raw and process materials and technology controlling and process test method ".By Integrated comparative, have selected the electroceramics cement glue formula that cost performance is relatively best.Proportioning and the physicochemical property of formula are as follows:
(1) electroceramics cement glue composite material type formulation ratio:
| Aluminosulfate cement | Mucilage binding quartz sand | Water | Admixture | Silicon powder | Glass fibre |
| 100 | 50 | 27 | 0.4 | 2.6 | 0.09 |
(2) electroceramics cement glue composite material type formula moulding process:
Test pilot scale cement mixer and cement mortar shaking platform carry out.
(3) test block of electroceramics cement glue in the early strength performance of maintenance after seven days as following table:
| Test event | Test result | Tradition performance |
| Folding strength | 17.44MPa | 12.32MPa |
| Ultimate compression strength | 105.21MPa | 59.42MPa |
Can be drawn by upper table adopts the electroceramics cement glue composite material type of technique scheme formula tool to have the following advantages: 1) electroceramics cement glue early strength exceeds very many compared to traditional cementing agent; 2) interpolation of silicon powder and glass fibre, improves the resistance to compression of electroceramics cement glue, cracking resistance, freeze proof, anticorrosion and physical strength etc. aspect performance.
