Abstract
An EVA elastic rubber brick and its production are disclosed. The process is carried out by crushing foaming waste EVA and waste rubber powder into solid grain, laying them into container proportionally, adding into polyurethane adhesion agent, anti-ageing agent and coloring agent, agitating to obtain mixtures, putting it into mold, and molding while vulcanization forming by vulcanizer at 1-5MPa and 80-100degree for 30-60mins. It costs low and has excellent elasticity.
Description
Technical field:
The present invention relates to a kind of brick.Especially relate to a kind of EVA elastic rubber brick and preparation method thereof.Be mainly used in athletic grounds such as physical culture that laying needs tool elasticity to require, body-building, can also be applicable to need have sound-absorbing, the installation of the metope of shock-absorbing requirement.
Background technology:
Before the present invention makes, generally adopt plastic cement to lay at present on athletic grounds such as physical culture, body-building, also there is the simple waste old brick of employing to lay.It is relatively poor that the former plastic cement is laid elasticity, and material cost is higher again; And the simple waste old brick laying of latter elasticity is relatively poor equally, and starting material are in short supply, and material cost is higher.
Summary of the invention:
The objective of the invention is to overcome above-mentioned deficiency, a kind of good springiness, the useless EVA elastic rubber brick that the cost of material is low and preparation method thereof are provided.
The object of the present invention is achieved like this: a kind of EVA elastic rubber brick, and it is to be main raw material with foam useless EVA particle and waste rubber grain, is equipped with urethane and makes tackiness agent, adds anti-aging agent and tinting material again, described each raw-material weight proportion is:
100 parts of the useless EVA particles of foaming
Waste rubber grain 10-30 part
Polyurethane adhesive 5-10 part
Anti-aging agent 1-3 part
Tinting material is an amount of.
EVA elastic rubber brick of the present invention, the Ethylene Propylene Terpolymer particle that also is equipped with 5-10 part in the described raw material is interspersed as colour.
EVA elastic rubber brick of the present invention, the useless EVA particle specification of described foaming is the 3-5 order, the waste rubber grain specification is the 5-15 order.
EVA elastic rubber brick of the present invention, described Ethylene Propylene Terpolymer particle 5-8 order.
The preparation method of EVA elastic rubber brick of the present invention, this method comprises following processing step:
Step 1, pulverizing
Foam useless EVA and waste Crumb rubber are broken into the solid granular of required specification;
Place in the stirred vessel by will foam useless EVA particle and waste rubber grain of proportioning, add polyurethane adhesive, anti-aging agent and tinting material, mix, make mixture;
Step 3, compression molding
The mixture that step 2 is made places in the mould, and with the moulding of vulcanizer molded vulcanization, curing temperature is controlled at 80-100 ℃, and pressure-controlling is at 1-5Mpa, and the time is controlled at 30-60min.
Because the present invention adopts the useless EVA particle of foaming to come part to replace waste rubber grain, is equipped with the Ethylene Propylene Terpolymer particle again and intersperses, and compares with simple waste rubber brick, has characteristics such as good springiness, raw material sources are wide, cost is low; Compare with common synthetic court, also have characteristics such as good springiness, cost are low, also having solved the pollution that the useless EVA of foaming brings to environment, and can recycle.
Description of drawings
Fig. 1 is the Facad structure synoptic diagram of EVA elastic rubber brick of the present invention.
Among the figure: the useless EVA particle 1 of foaming, waste rubber grain 2, Ethylene Propylene Terpolymer particle 3, polyurethane adhesive 4, polyurethane adhesive 5.
