Problems solved by technology

[0003] Due to the special position function of road bridge beams (long-term exposure, load bearing, expansion and contraction), it is required to have better curing speed, special adhesive force and long-term thickness resistance. At present, the connecting expansion joints of domestic viaduct roads use Due to the poor weather resistance of natural rubber, after three years of use, there will be aging cracks, foreign matter and rainwater leakage. The road takes a long time, and generally requires unilateral road closure for ten days / km, resulting in high social utility costs

preparation example Construction

[0030] The invention discloses a method for preparing glue for road and bridge, which specifically comprises: first mixing a base material and a crosslinking agent uniformly according to a required ratio to obtain a premixed material, and then adding a silane additive and a catalyst and mixing uniformly.

[0031] The mixing is carried out under negative pressure.

[0032] The raw material composition of the base material also includes quartz powder and nano silicon dioxide, and the weight ratio of the quartz powder, nano silicon dioxide and 107 glue is 25~30:2~4:60;

[0033] The base material is prepared according to the following method:

[0034] First mix 107 glue, quartz powder, and nano silicon dioxide according to the required ratio, and then dehydrate at 110-130°C.

[0035] The raw material composition of the glue also includes carbon black, and its weight ratio to the base material is 25-35:1000;

[0036] When preparing the premix, the carbon black is mixed with the b...

Abstract

A kind of glue for road and bridge, its raw material composition and weight ratio include: base material 1000, crosslinking agent 40-50, catalyst 0.5-1, silane auxiliary agent 30-35, the raw material composition of base material includes 107 glue, The raw material composition and weight ratio of silane additives are: polyethylene propylene-methoxyethoxy multi-crosslinking point silane 15-20, T-shaped epoxy silane 4-6, polyepoxy silane 4-6 , aminomethyl silane 1~3, aminopropyl silane 1~3, amino multi-crosslinking point silane 1~3, when preparing, firstly mix the base material and crosslinking agent according to the required ratio to obtain the pre-prepared Mix the materials, then add silane additives and catalysts and mix evenly. This product not only has a wide range of bonding, excellent weather resistance, but also is convenient for construction.

Description

technical field [0001] The invention belongs to the field of material bonding, and in particular relates to an adhesive for road bridges and a preparation method thereof. Background technique [0002] Silicone rubber is a kind of ointment-like material that will solidify into a tough rubber-like solid when exposed to moisture in the air. It is mainly divided into dealcoholized, deacetic acid, deaminated and depropylated. Silicone glue is widely used in construction, industry, electronics industry and other fields due to its natural thickness resistance. [0003] Due to the special position function of road bridge beams (long-term exposure, load-bearing, expansion and contraction), it is required to have better curing speed, special adhesive force and long-term thickness resistance. At present, the connecting expansion joints of domestic viaduct roads use Due to the poor weather resistance of natural rubber, after three years of use, there will be aging cracks, foreign matte...
