A sealing composition of single component type is formulated from known sealing composition components and a novel acrylic copolymer comprising 68-96% by weight butyl acrylate and/or 2-ethylhexyl acrylate, 0-20% by weight methyl methacrylate and 4-12% by weight of an oxidative monomer having the general formula: <IMAGE> where R = H or CH3, and n = 1 or 0.
Description
SPECIFICATION
Novel polymers and sealing compositions containing same
This invention relates to a novel copolymer of acrylic type, and to sealing compositions of single component type formulated from said copolymer.
Known types of acrylic sealing composition are of a plastic character. An acrylic solvent polymer is thermoplastic as the polymer is dissolved in its own solvent. In order to obtain a usable viscosity, one is limited to controlling dryness and molecular weight.
If a di-functional or a tri-functional monomer is polymerized in a solvent polymer of the above type, the molecular weight increases and a certain elasticity is obtained, but even with a small quantity of di-functional monomer the viscosity becomes unusable.
The manufacture of elastic sealing compositions is by no means new. Silicon, polysulfide, and urethane compounds are examples of such sealing compounds. It has now been discovered that sealing compositions based on acrylate polymers and which have elastic characteristics after application can be produced. This means that during preparation and application, relatively low molecular weight and viscosity and hence very good handling qualities can be provided. Elasticity and increased molecular weight are obtained by means of an oxidative process.
The present invention provides a copolymer useful as the basic component of a sealing composition of single component type and comprising: 6896% by weight of butyl acrylate and/or 2-ethylhexyl acrylate, 412% by weight of an oxidative monomer having the general formula:
wherein R is hydrogen or methyl and n is O or 1, and 0-20% by weight of methyl methacrylate.
The novel copolymers may be prepared by polymerizing said butyl acrylate and/or 2-ethylhexyl acrylate with said oxidative monomer and optionally said methyl methacrylate in the presence of from 0.41.5% by weight of azoisobutyronitrile or benzoyl peroxide as an initiator, a solvent of xylene and/or toluene type, and optionally up to 1.2% by weight of tertiary dodecyl mercaptan and/or up to 0.3% by weight of monothioglyceryl as a chain-linker to regulate the molecular weight of the polymer and therefore its viscosity, said percentages being based on the dry weight of said monomers.
When formulated with a suitable solvent in amount of from 1025%, the present copolymers provide a polymer oxidative component for a sealing composition of single component type.
From the oxidative polymer basic component as described in this invention, plus conventional sealing composition components, a new sealing composition of single component type can be produced. This new sealing composition is elastic and adheres well to various surface materials. It is also strong and has good filling qualities, little shrinkage and temperature sensitivity and is age resistant and can be painted over.
The oxidative polymer basic component shall be included in the sealing composition as described in this invention in a quantity equivalent to 3070% by weight calculated on the dry weight of the sealing compound. Also included are conventional siccative substances, and optionally retardant and thixotropic substances as well as fillers such as chalk or talcum and a pigment if a coloured sealing composition is required.
Suitable siliccative substances are cobalt naphthenate, zirconium naphthenate or iron naphthenate or alternatively iron octoate. It can be generally assumed that the required quantity of siccative substance should be from 0.01 to 0.3% by weight calculated as the quantity of metal and based on the quantity of the polymer basic component. However, the quantities which are suitable vary with regard to the metal in question. The following values are assumed to be representative:
Co = 0.01--0.08, Zr = 0.05-0.3, and Fe = 0.030.3% by weight, all calculated as the quantity of metal to the quantity of the polymer basic component.
A suitable retardant is methyl ethyl ketoxime which should be included in a quantity equivalent up to 0.05% by weight calculated on the polymer basic component. However, a retardant can be omitted if there is a low siccative content and/or there are low storage resistance and rapid hardening requirements. Thixotropic substances which can be used are eg, silicon acid, volcanic ash and/or acrylonitrile fibres. A suitable quantity of thixotropic substance is generally from 530% by weight calculated on the basic component. This quantity varies however with the choice of thixotropic substance. For example, a more suitable quantity of silicon acid is 512% by weight.
The oxidative polymer basic component in accordance with the invention shall have a dryness of 7590% when it is added to the sealing composition. The remaining quantity i.e. 1 0-25%, consists of a suitable solvent, such as xylene or toluene. The sealing composition according to the invention receives its elasticity from the oxidative monomers contained in the basic polymer component. As noted, these monomers have the following general formula:
where R = H, alternatively CH3, and n = O or 1.
When R = CH3 and n = 1 the compound is named dicyclopentenyloxyethylmethacrylate.
When R = H and n = 0, the compound is named dicyclopentenylacrylate.
And when R = CH3 and n = 0 the compound is named dicyclopentenylmethacrylate.
Today these monomers are sold as polymerizable solvents. A monomer of this special type and certain other areas of use for the said monomer other than those applicable to this invention are described in the Swedish patent application 81.022964. The said patent application contains a description of this solvent polymerisation which includes the said monomer but with low dryness and a proportionally high oxidative monomer content. The said patent application gives the impression that it is intended for use in products for surface treating and consequently products which contain a high T.In contrast, for use in the sealing composition according to the invention, the present copolymers shall contain the oxidative monomer in a quantity of only 4-1 2% by weight In addition the present copolymers contain 6896% by weight butyl acrylate and/or 2-ethylhexylacrylate as a softening agent and 0-20% by weight methyl methacrylate as a hardening agent.
To regulate the molecular weight of the present copolymer, and consequently its viscosity, chain linkers such as tertiary dodecyl mercaptan and/or monothioglyceryl can be utilized and suitable quantities of these particular molecular weight control agents are 0-1.2% by weight and 0-0.3% by weight, respectively, calculated on the dry weight of the basic component. However, with low dryness and oxidative monomer quantities in the basic component the copolymers can be produced without a chain-linker.
Examples of suitable initiators for use when producing the present copolymers are azoisobutyronitrile and benzoyl peroxide, in quantities of 0.41.5% by weight calculated on the dry weight of the polymer.
In general, the copolymer according to the invention is advantageously produced by adding the entire quantity of solvent to a reactor and, while continually mixing, adding initiator, monomer mixture and chain-linker if required. The temperature in the reactor is suitably 85-1 400C and the total process time until the finished basic component is obtained is-suitably approximately 25 hours of which 4-8 hours are used for the addition of the relevant components which preferably are added in 6-1 5 portions whilst the remainder of the time is used for the post-reaction during which only initiator is added. By this process, the polymer oxidative component containing 1 0-25% of solvent, preferably of type xylene and/or toluene, can be directly produced for use in formulating a sealing composition of this invention.
When producing the finished sealing composition as described in this invention the basic component is mixed with the previously mentioned siccative, and optionally retardant thixotropic substance, filler and/or pigment.
The sealing composition according to the invention gives an elastic sealing after hardening which, due to marginal shrinkage and good adhesion to the neighbouring surfaces of the joint, fills the joint very well. The hardened sealing composition is also very resistant to weathering.
According to an alternative embodiment of the sealing composition of this invention, 50% by weight of the basic components can be replaced by an equivalent quantity of thermoplastic acrylate solvent polymer having a Tg of approximately --100C.
From the basic component according to the invention, transparent or semi-transparent sealing compositions can also be produced by (apart from siccative and optionally retardant) adding only a suitable thixotropic substance and avoiding coloured filler and pigment. In such a case the quantity of thixotropic substance suitably would be between 812% by weight calculated on the quantity of the basic component.
The invention is illustrated by the Examples which follow.
Producing the polymer basic component
The following method for producing the basic component was utilized in all the Examples.
To a reactor was added a mixture A consisting of a lesser quantity of the necessary initiator dissolved in the entire quantity of solvent. The mixture A was heated in the reactor to a temperature of approximately 700C. The other components, with the exception of a smaller quantity of initiator which was saved for the post-reaction, were prepared simultaneously as a mixture B which was then added to the reactor in several portions. As the polymerisation reaction is exothermic the temperature of the mixture increased with the addition of each portion of the mixture B to the reactor. By cooling the reactor the temperature of the polymerisation mixture was prevented from exceeding 1 10--1300C and immediately its temperature has spontaneously dropped to 96-980C the next portion of the mixture B was added.
When the temperature had spontaneously begun to drop after the final portion of the mixture B had been added, two portions of pure initiator were made up for the post-reaction. During the postreaction the temperature was maintained at approximately 800C.
The addition of mixture B was carried out in 1 0-20 portions. Each complete production of the basic component according to the invention required approximately 25 hours.
