Abstract
A high-molecular alloy brake block is prepared through cutting ethylene propylene rubber, backing, adding silica rubber, plasticizing, adding addition agent, pugging, adding short glass fibres and unsaturated polyester, pugging, and sulfurizing. It has high strength, elasticity and resistance to high temp and abrasing.
Description
Technical field
The present invention relates to a kind of preparation method of brake block, particularly relating to a kind of is that primary raw material, unsaturated polyester (UP) (DMC) are the preparation method of the composite material brake block of reinforcing agent with rubber.
Background technology
The brake block of using on the at present domestic and international automobile mainly divides two kinds: the one, and metal brake block; The 2nd, asbestos are mixed the brake block of metal powder.The higher relatively lightness that is unfavorable for automobile of metal brake block weight, and asbestos metal powder brake block intensity is lower, wears no resistance, and also poisonous.These two kinds of brake blocks hinder the auto industry develop rapidly.Therefore, scientist both domestic and external is seeking a kind of new traditional brake pad material of material substitution.
Summary of the invention
Technical problem to be solved by this invention provides a kind of preparation method of brake sheets made from macromolecule alloy, to remedy the deficiencies in the prior art and defective, meets the demands of production and living.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of preparation method of brake sheets made from macromolecule alloy comprises the steps: that (1) cut glue, dry for standby with EP rubbers (EPDM).(2) film that obtains of step (1) and silicon rubber are to plasticate 8～10 minutes in the mill of 0.5～1 millimeter of 40～50 ℃, roll spacing in the roller temperature, obtain broken-down rubber.(3) in broken-down rubber, add compounding ingredient, adjust the roller temperature and be 1～2 millimeter of 50～60 ℃, roll spacing, mixing 25～30 minutes, make elastomeric compound; Be in the mill of 1～2 millimeter of 50～60 ℃, roll spacing mixing 10～20 minutes in the roller temperature with elastomeric compound, the unsaturated polyester (UP) (DMC) of dosing staple glass fibre, the DMC/EPDM/ silicon rubber intermingling material that obtains mixing was parked 4～12 hours.Wherein, EP rubbers, silicon rubber and the mass ratio of dosing the unsaturated polyester (UP) of staple glass fibre are: 1: 2～5: 3～6.(4) intermingling material that step (3) is obtained vulcanized 20～30 minutes under 165～170 ℃, 8～12MPa condition.
As optimized technical scheme: described silicon rubber is methyl vinyl silicone rubber, technical grade;
Described compounding ingredient is the composition of carbon black, zinc oxide, vulcanization accelerator, vulcanizing agent, and its quality proportioning is: 40: 5: 0.8: 5;
Described vulcanization accelerator is a dibenzothiazyl disulfide;
Described vulcanizing agent is a kind of or its mixture in cumyl peroxide or the dibenzoyl peroxide;
The described unsaturated polyester (UP) of dosing staple glass fibre is the DMC that Harbin Insulation Material Factory produces;
Described EP rubbers is ethylene propylene diene rubber.
The invention has the beneficial effects as follows: preparation method's technology is simple, production efficiency is high, advantage such as the brake pad material of preparation is heat-resisting, wear-resisting, mechanical strength is high, nontoxic, good toughness.Enough pair of roller mill of described alloy material energy and vulcanizer carry out the one-shot forming preparation, have reduced the input of brake block equipment, have simplified its production technology.The prepared alloy material of the present invention can be in military fields such as automobile, space flight and aviations as framework material or case material.
