Abstract
The present invention relates to a polyurethane rubber diaphragm. It is characterized by that its composition includes (by weight ratio) polyurethane raw rubber 100, stearic acid 0.4-0.8, carbon black 32-40 and accelerator 3.2-4.0. Said invention is applicable to various diaphragm pumps.
Description
Technical field
The present invention relates to the diaphragm that a kind of diaphragm pump is used, particularly a kind of rubber diaphragm of polyurethane.
Background technology
In thin pulp is carried, often use impeller pump or diaphragm pump.For example, in the mine ore dressing process, generally adopt impeller pump or reciprocation pump to carry the slag slurry, reciprocation pump and impeller pump compare, and the wearing and tearing of impeller pump are big, and work-ing life is short, and the wearing and tearing of reciprocation pump are little, long service life; Can improve operational throughput, save the maintenance number of times with reciprocation pump, significantly reduce and carry cost.Therefore, in the slag slurry in mine was carried, reciprocation pump was the product of the update of impeller pump.In reciprocation pump, diaphragm is a vitals, also is consumable accessory.This diaphragm shapes is simple, and its structure is to be embedded with hardware in sheet rubber.The problem that runs into when adopting reciprocation pump is that homemade reciprocation pump diaphragm-operated is on the low side work-ing life; Though this diaphragm life-span of external import is high, costs an arm and a leg, and is about a times of homemade diaphragm price.The general elastomeric material that adopts of import diaphragm is a chloroprene rubber, and generally be about 6000 hours work-ing life; And only be 2000 to 3000 hours diaphragm-operated work-ing life of domestic production.How improving the reciprocation pump diaphragm-operated life-span, reduce its production cost, is one of the important tackling key problem content in present technique field.
Summary of the invention
The purpose of this invention is to provide a kind of rubber diaphragm of polyurethane to solve low problem of homemade diaphragm life-span.Diaphragm of the present invention is concentrated on studies to test through the contriver and is finished for many years.In the diaphragm-operated prescription, adopt the main raw urethanes to replace chloroprene rubber, this product rubber diaphragm of polyurethane has the advantage that price is low, the life-span is high.
The objective of the invention is to realize by following technical scheme.Rubber diaphragm of polyurethane of the present invention is made of by weight proportion following component:
Urethane rubber 100
Stearic acid 0.4-0.8
Carbon black 32-40
Promotor 3.2-4.0.
Material mark in the above-mentioned prescription is:
Urethane rubber HA-5 100
Stearic acid SA 0.4-0.8
Carbon black SAGN110 32-40
TM monex TD 3.2-4.0.
The preparation method of described rubber diaphragm of polyurethane may further comprise the steps:
1) material in will filling a prescription is mixing on mixing roll,
2) mixing film is cut into the diaphragm blank,
3) in the diaphragm blank, bury metal connecting piece underground,
4) with after the preheating of film tool, the diaphragm blank is put into the film tool,
5) the film tool is closed, pressurization, heating, sulfuration,
6) the finished product diaphragm is taken out in the demoulding.
In sum, rubber diaphragm of polyurethane of the present invention adopts the urethanes unique formula, improves quality product significantly, is the rubber diaphragm of polyurethane that a kind of cost is low, the life-span is high.The present invention is applicable on the various diaphragm pumps and uses.
