Problems solved by technology

For shock-isolating rubber bearings with a pure rubber layer thickness of more than 100mm, the vulcanization time is usually 400-500 minutes, and for large-scale thick products, the vulcanization time can reach 1200 minutes, that is to say, the shock-isolating rubber bearings only use traditional flat plates The vulcanization efficiency of the vulcanizing machine is relatively low. It is common to produce 1-2 pieces of products in a single mold within 24 hours. This problem is common in all thick rubber products.

[0043] The invention provides a building shock-isolation rubber bearing, and the preparation method comprises the following steps:

[0044] a) Preparation of rubber compound: preparing and processing the rubber compound according to the formula;

[0045] b) Cut the steel plate according to the size requirements;

[0046] c) After the mixed rubber is rolled back and cut into pieces, the adhesive is bonded to the cut steel plate to form a semi-finished product to be molded;

[0047]d) Put the semi-finished product to be molded into the heating device for preheating. After the preheating process is raised to 75°C-85°C at a speed of 5°C / min, the holding time is longer than 4h; the preset temperature upper limit is 85°C, according to the rubber The shear elastic modulus G value of the rubber is different, and the preheating time is different, but the preheating time is not less than 4 hours;

[0048] After the preheating time is reached, measure the temperature of the center of t...

Abstract

The invention provides a preparation method of a building shock insulation rubber support and the building shock insulation rubber support product prepared by applying the same. The preparation methodcomprises the following steps that firstly, a rubber compound material is prepared, a steel plate is cut, and laminating and forming are carried out on the rubber compound material and the cut steelplate subjected to shot blasting to obtain a semi-finished product to be subjected to mold filling; the semi-finished product to be subjected to mold filling is placed into a heating device for preheating, and after the temperature rises to 75-85 DEG C at the speed of 5 DEG C / min in the preheating process, the temperature is kept for more than 4 hours; mold filling and vulcanizing are carried outon the preheated semi-finished product; and demolding and trimming are carried out to obtain the building shock insulation rubber support. By adding the preheating step, adjusting the formula and improving the process, the vulcanization uniformity and the vulcanization efficiency of the building shock insulation rubber support are effectively improved.

Description

technical field [0001] The invention relates to the technical field of preparation of building shock-isolation rubber bearings, in particular to a method for preparing building shock-isolation rubber bearings and products thereof. Background technique [0002] The traditional anti-seismic technology is to firmly connect the superstructure and the foundation of the building. In order to build a stronger house, thicker steel bars and more concrete are poured, but the anti-seismic effect is not ideal. The seismic isolation bearing is to add a seismic isolation layer between the upper structure and the foundation, and install a rubber seismic isolation bearing to play a role of soft connection with the ground. Through this technology, about 80% of the energy of the earthquake can be offset. The rubber shock-isolation bearing is a kind of shock-isolation bearing, which is composed of multiple layers of steel plates and rubber alternately laminated. It can not only reduce the hor...
